Many years experience with various diesel heaters during a 22 year career in the trucking industry. Prevent the clogging/sooting by running on highest temp setting for 1 hour each week. Large trucking company maintenance shops and Thermo-King recommended. Keeps the system clean and running👍. Doesn’t hurt to run on high more often either if running for long periods of time

Always run the heater on the highest setting for 5min before you shut it down. Try not to run it on it's lowest setting (I.e. if you have say 1.3 to 5 Hertz pump settings try to stay above 1.6 or greater). If you never run it on high before shutting down you will have to dismantle it and clean the burn chamber and glow plug hole. Make sure the tiny hole next to the glow plug is clear. Finally if you still have problems change the glow plug and make sure your fuel line is feeding constantly up from your fuel pump to the heater. Air bubbles form in the pump and must be released evenly upward for proper combustion. My 2cents, take care 7.

Seven, I congratulate you on your acquired skills since purchasing your van. You've learned well and have grown your knowledge and abilities by leaps and bounds. Learning your tools and now becoming a tool maker of sorts. A similar tool with a slot is used to change oxygen sensors on vehicle exhaust systems on cars and trucks. You're learning. You've had that heater now for quite a while and it's worked well for you. When you finally do get it fixed you will have learned much. Good Luck and we're all rooting for your success. Thanks and we'll be waiting for your next informative video.

Excellent video Seven. Thanks for sharing a failure. As an RV owner who prefers to do his own upgrades and repairs I really enjoy these working through issues videos. They’re not always a rosy ending.... Also its awesome to see so many people in the comments who are willing to offer advice and tips.

Thanks for all the info Seven. We installed our diesel heater shortly after seeing you at skooliepalooza. So far ours has been working well. This is good info to have if we start to encounter problems! 👍

The black plastic tool is an installation tool not a removal tool. I would buy a few screens, they can be difficult to remove and install. I would also keep a glow plug on hand. You can get it with the socket included. Smoke is caused by poor ignition source. Glow plug could be bad or dirty. A small piece of emery cloth can clean it up. You also need to clean the hole where the screen is installed before reinstalling with the tool. You need to make sure it is installed completely so the glow plug does not damage it when installed.

Well heck the failure is a part of diagnosing the problem. Between your efforts and your subscribers I'm certain you will be up and running for the warmer weather. ;-) Remember your "failures" will be valuable lessons and posting this will help many!

I appreciate your honesty in trying to figure this out. you'll figure it out!

Wow very impressive 7 you're repairing something on your own. Wow very impressed 👍 awesome video. Jams Russel has the cure. You very close. There famous for glow plugs going bad. You will get it 👍👍👍🛠️🇨🇦🇨🇦

To clean the blast tube (when sooted up ) I use a propane torch and place in blast tube and cook for a while then I use compressed air while still hot to blast in it to super heat the ambers still in blast tube. I then wash it with some strong detergent and blow out. The other thing to look for is the disc in blast tube ...it is not secured and may have shifted in the tube so ck it also make sure it is all the way out and on the ridge stop in tube . I have also found that the fan is an issue with these heaters and the problem is the air gap to the hall effect magnets. I just take a hammer and tap the fan rotor in a little and usually solves the issue . Hope this helps someone .

I have a 2Kw heater installed in my car, I always run it at 1.0hz, rpm fan speed 1500. It’s been on 3 winters and its running fine, no smoke from a start up. I opened it now and found out that there was no soot or carbon build up. Now I change the glow plug and the screen atomizer.

Seven buddy glad to see you back. Been wondering with this virus thing. You have lots of info so I'm not gonna add to it. Glad you're on when you fix it please let us know. Rock on my friend.

Soot / carbon build up in heater. If you can't burn it out on High, which is unlikely, you'll have to take it apart and clean. Always run on high for a couple minutes before you turn it off when you use the heater.

Seven , The white smoke tells you , your grow pin is working, because the glow pin is heating up the burn chamber and the fuel pump is working because you can here it pulsing. Hover the Flash point is not being reached hence the white smoke, Carbon build up in the burn chamber obsorbes the heat from the glow pin and does not allow the chamber to get up to flash point tempture and fire up the heater. When you strip down the chamber pay good attention to the cleaning the carbon at the top end "the glow pin end". Stay safe Mick.

yo - 7 . good show . thanks for trying and sharing with us .

Seven, glad to see you in there fixing stuff, you've come a long way since back in the day when you purchased the SV. I'm going out on a limb here, you should've kept the buddy heater... The operate word is Chinese, that says it all. Brought to you from the people who brought you Covid-19

My new unit started cavitating the fuel in the fuel pump. I could see tiny bubbles exiting the pump but not entering the pump. Ordered a new pump on Amazon and installed. Heater fires right up and cleaned itself right up. When it was funning lean, there was enough soot building up inside the unit that my outlet temps dropped to 110 from 210 fahrenheit. All good now.

I am a little late to the party here but The Campulance Man had a very similar issue with the smoke, etc. He eventually found out that his was an elevation problem. He had to manually change the furnace settings for whatever elevation he was at. Hope that helps.

I know nothing... Hope you keep us informed Be safe. Many blessings

Hi Seven! Great to see ya! I've got 4 of these things in service between work trucks and bus. So after my first year, went to start using again similar issues. I bought the same stuff as you. Oh yes one had a fuel pump failure. Tried shopping for that, just bought another for spare. So seems like having an extra while I renovated the other. Also I don't have my note pad with me here, but I tried to write down all the error codes so when I'm not internet connected I'm not completely lost! LOL! My friends all tell me the same as someone else mentioned to execute that purge cycle before completely shutting down. I did keep trying on one unit that smoked and it eventually burned off I guess! John there from Australia video was very helpful. You just keep trying, but I just replaced with new, till I had time to execute the repairs, which left me with spare parts I could not have bought! I sometimes wondered how many would I buy before the point of just getting a Webasto, but looking at reviews on them, they have similair "maintenance" issues. Webasto's controller has better functions/algarthymes for air/fuel mix. Also High Altitude functions. So a lot has gone into it thus the cost. The controllers I've gotten with these Chinese copy diesel heaters and the controllers have been some perfect, some seem like only part of the program works! Such as the "shutdown" or purge cycle. I'm still very thankful someone made these at this price point, it has improved my comfort a lot! But you gotta expect to have to service them! LOL! [Thus two on the bus, so at least I'll have a back up".

Hope you get everything sorted out.

Mine does that when my deep cycle battery is low on charge. If i start my engine the extra amps make the glow plug hotter and it ignites! Thanks for the great vid.

The error code indicating low voltage may be the key here, these can also operate on 24v, you can check the voltage setting and adjust it via the main menu, which is accessed by a code which is available from other youtube videos.

I know you said you didn't have a voltage problem but when I first connected up my heater I connected it to my vans 12v wiring that connected to my battery.. the heater gave me the same error... The solution was to get the heater its own battery now it works everytime

Hi I was watching your video as I had problems with mine.. I noticed that you had placed the new gauze ... And just fitted the glowplug.. But what I do is check that the glowplug is right down in its recess and clear of this tiny inlet air hole which must not be blocked..

Carbon buildup is a big problem even with the higher end brands. It basically requires pulling the whole thing apart to clean. Glad you’re doing well my friend. Let me know if you head my direction.

Mine was doing same thing . Ended up putting a vacuum cleaner on the exhaust for a couple of seconds during initial startup and the heater fired up right away . Disclaimer : not sure if it pulled carbon from exhaust or just pulled oxygen into combustion chamber to help it fire. Heater has worked great ever since.

Thank you for the video. Have a blessed day.

Thanks for sharing, even failures teach. Like #26. I don't think it is the glow plug because you are getting smoke. Was the screen you replaced the EXACT same? Maybe it isn't properly placed.

They are called box spanners,. if you buy a glow plug off e-bay you get that little box spanner and gauze with it complete with slot on the side, don't forget to clean out the little hole on the side of the glow plug hole while the plug is out, otherwise you will have white smoke coming out because the fuel CANNOT mix with the air to ignite the fuel.

Have you tried easy start in the inlet cleans every thing in 1 hit

Best video yet,thank you .

you need to ramp up the heater to high prior to shutting it down or it will carbon up badly

I have a Webasto gas heater, and if I don't run it for a while it keeps shutting down on me until it gets gas then it starts up and runs perfect. I didn't start it for almost three months during the summer ( I know you're supposed to start it at least once a month and let it run full blast for at 30 minutes to clean it out) but it stopped on me 6 times then it started running. I don't recall if there was smoke though.

The not starting up/white smoke is an indicator that there is soot build-up near the glowplug, I figured out that there is a tiny 3mm hole next to the glowplug that let air in to help combustion/Ignition at startup. I cleaned mine 2 times but overlooked this tiny hole, and suprise surprise it still didn't work and wouldn't start up, after the third time I discovered the tiny hole, unclogged it and it would start right up without any smoke or delay. It was not the glowplug nor the little gasification screen inside the unit where the glowplug sits, just the tiny hole. You have to open the unit up to see the hole.

Does anyone know the btu conversion from kw for these?

Good video. Unfortunately everything doesn't work out like we want. I can't wait until the next video.

How many hours do you think you had on it?

Running it on 1 is not a complete burn, so run it on 3 for 15 minutes every few hours!

I had the same problem with mine very easy fix was pouring out white smoke and not firing all I did was disconnect the fuel line let it run till all the smoke goes away then took a syringe filled it with diesel and injected into the line so no air was in the line and it started running as supposed to hooked fuel line up right quick and has been running fine since then hope this works for you like it worked for me

if you cut the end of the special tool off I think it will work (I think that's why made that way), second thing try taking power away (letting it reset itself, it may clear the code)

I had a D1L eberspacher! It smoked all the time. It had no screen in the glow plug chamber. I’ve tried everything, and finally burned out the fourth dollar glow plug, so now it’s going in the garbage pile! I am getting a new Chinese one next week for the price of a couple of glow plugs. Hopefully I can give my lungs a break from the smoke

That tool 🔧 is Only for replacement of the Aspirator Gauze, if that much dirty soot, check for clean inside especially the hole near the air intake to that Aspirator Gauze, the outside pipe might be packed up with soot on the outlet, water 💧 in the Exhaust, but sorry to say you need to take the unit apart, buy the new seals two you will need, If you have been burning 🔥 used engine oil 🛢 yes 👍 you will need to dismantle the unit for a good clean up.

I would check and make sure the glow plug is functioning properly.

I bought a larger diesel heater with my second one, but now I leave it on the lowest setting and came across this problem. I knew the consequences but wasn't sure how certain the effects would be, sure enough just a couple moths of only running on the lowest setting clogged it up

Is your heater a 2kw?

Hello had the same problem. The smoke but mine shut down after 5 minutes and won't restart how ever many times you try it needs to rest all day and it will start next morning. I think it not enough electric power we will see

Been thinking of getting one of these. Hope you a re successful getting this fixed. Would be good to know what went wrong.

It looks like the glow plug is bad.

It is flooded with diesel. I had the same issue and was getting an E-10 code. What happens is if it doesn't fire up the first time then there is unburned fuel in there then when you try it again the pump comes on putting more fuel in further flooding it. Here is the fix : remove the retainer clip from the fuel pump wiring connector but do not unplug it just yet or you will get a fuel pump error, now start it as usual once you hear the pump start pumping unplug it, let the heater run, listen, you will eventually hear it fire wait another 10 seconds to let it burn off the excess fuel then plug the fuel pump back in. Run the heater on high for at least 10 minutes to clear out the soot. It should run normally now. If not you will have to repeat the process.

Blow air into the muffler. Sometimes it just needs a bit more oxygen to get started. Don't know why, but that can cause it to fire up.

I had the same problem, it ended up to be the power supply 12v battery although the multimeter and charger said ok, it wasn't. They draw about 15amps on start up. Worth checking

When you had it apart did you check the breathing orifice where the glow plug turns in.

I'm sure it's fixed by now, but I installed a genuine webasco glow plug in my Chinese heater, and tuned it lean, havnt had a problem since, have spare hq bearings on hand for next tear down.

Well that had to be frustrating. Your valiant effort has not yet paid off but hopefully it soon will. Here's to a toasty warm & safe home soon.nice to see you Seven!

So, we didn't hear any videos for a fix. Did you find the problem?

Hi and thanks for the video. My heater is brand new and just installed with exactly the same issue except mine blows huge clouds of white smoke and diesel drips out of the drainage hole in the exhaust muffler.. I sen a video of the issue to the supplier and they are sending me a new how plug and pump that they say will fix the issue?? I’m still waiting on the parts and wondering if you’ve finally fixed your heater

Wonder if it would help in the future to run an inline fuel filter. Possibly a small second tank using K1 kerosene because it burns much cleaner.

Ad a bit of starting fluid on the exhaust and that's it !

I’ve had this problem, it turned out there was a tiny air leak in the rubber fuel pipe connector. I readjusted this and it worked fine for about 3 months then it started blowing cold air. I replaced the temp sensor and it works fine now. I’ve brought back up temp sensor, mother board and rubber fuel line Incase I have the problem again. Also replace all the fuel line with the one they give you as it’s prone to leaking and splitting. Hope this helps someone?

In my bus i have a 30kw diesel heater when its start smoking. Its only sot on glass for fire checker.. Its get a lot sot so heater dont know if its started or not. Its smoks a alot when that happens

Where the mesh goes in the glowplug, you'll have a hole that needs to be clear. Sometimes it clogs up.

1. bad glow plug. 2. back pressure issues due to wind (i heard that back pressure issues can be caused by having the exhaust pipe angled such that water builds up in the pipe causing problems). you can disconnect the exhaust pipe from the unit and if starts ok then it probably something blocking the exhaust. 3. bad fuel or blocked fuel line or failing fuel pump. 4 bad voltage (possible that you have a weak battery where it will show 12 volts under no load but crashes to like 9 or 10 when under load). charge battery or replace battery

Seven - where are you? Haven't heard a thing in quite a while. Hope all is OK. I'll be here when you get back.

When my heater on my truck did that it was because the blower in blast camber got stuck it will also throw a voltage code.

I have no experience with a heater like this. I would be sure nothing has obstructed the air intake from outside. And I suspect the entire inside of the burn chamber is clogged with soot build up. Uninstall it and take it completely apart and clean the inside. If that is smoke, the glow plug is working. But shouldn’t there be more volume of air blowing from the exhaust? Broken fan or air clog somehow.

Does your glow plug indicator showing? Check all plugs in. Volts is important how do you have it connected? To the batteries directly? If not, do so. What size of fuel lines are you using? 4mm to 6mm only and hard lines, no soft lines. I’ve have been using these heater for a long time and never had one go bad on me or my customers. Let me know maybe I can help you solve this. How do have fuel on the pressure side of the van fuel lines?

Same issue with mine still not resolved!!

Hi you will have to strip the heater and clean out the carbon. I have to do this once a month 😢

On a diesel engine you test the glow plugs my measuring the resistance of the plug. Set your meter to ohms and measure across the two wires going to the glow plug. The service data should show the proper value, or you can measure a known good. I also really doubt that finger tight is what you are looking for either.

If you have Facebook there is a group called Chinese Diesel vehicle air heaters - Troubleshooting & Parts sales.

. I found my exhaust smokeing because I had air building up in the line raise unit higher than the pump . fuel will have to pump up hill. Not level ..All uphill from pump onwards . And start it up on the lowest Hz 1.0 for 5 minutes untill fully going hot .. With a really good battery start truck and give it 14 volts.... Voltage might be good untill you load up a crap battery with the glow plug and it fails to start.

Whats going on Seven? are you ok? haven't seen any follow up on the diesel heater. fix it?

Did the diesel heater get fixed?

That tool is for installing the new screen

I've had a similar problem. It ignites and it starts to ignite and then it goes out. Then every now and then it works. I'm about to go and investigate. I'm going to investigate my fuel supply I'm going to investigate the little screen on the intake of the pump. I had a former heater and I would add compressed air into the intake and then it would ignite and heat then eventually decrease and eventually it would die. I replace the heater with a new heater but did not replace any other parts. Now it seems to be doing similar things. I'm also going to add fresh fuel. The fuel I had was from last year. I suspect it is a fuel issue just maybe a voltage issue. I'm going to check my whole fuel line to make sure it's all airtight. And also the intake part of the fuel in the tank. I have cleaned the screen and breathing orifice multiple times previously on the previous heater. This new heater has not work properly yet just randomly it works

B4 I shut down my unit I turn it on high and run it for a few minutes to burn of anything and then start the shut down process

Surprised you didn't buy a glow plug, faulty plug likely cause of excessive soot, and failure to heat the fuel enough to burn correctly

haven't heard fr om you in a while. You ok?

Does this unit contain a fuel filter?You may have a clogged up fuel filter.

Mine keeps shutting off and smells strong.

👍👍👍

It's not getting fuel. The cap on the fuel tank has a plastic inner that creates a vacuum, take it off or make a hole in the cap.

7, That's not smoke, it's diesel fuel vapor. Your not getting ignition. For whatever reason the controller is telling you it does not have enough volts to spark the fuel with the fan & glow plug & controller all using power. Check the heater supply wiring. It may have corroded or is dislodged or.... !

It is not a tool for removing atomiser.

I use kerosene and run every month on high for half an hour never had a problem runs super clean on kerosene

Saw something about the fan not turning freely causing a higher current draw and dropping the voltage to about 10v. This would cause an error 6 code...

Probably need glow lug?

Great seeing you learning all the new skills and trouble shooting since you got the van. Good luck with the repairs. Enjoy all your videos .

That red heater is a pain comen to fail the grey ones don't do that

Mine was blowing cold air before shutting down.. got on my tits. I bought another for £100. Took the old one out. Put on a stand, connected and fired it up.. at the same time spraying Easy start into the air intake.. ooooww it loved it, fired up, blew a load of black shit out, then carried on for an hour, running very clean, great heat and no smoke. Job sorted. Tested again later, perfect running no faults. Think the glow plug must have been caked in sut.

I would guess your igniter is gone bad, needs replacing.

It’s a glow plug mate

Error Code E - 06 is actualy motor failure

Here's a great rebuild or repair video on that heater. kzfaq.info/get/bejne/ja2UityQz7DWk6c.html

Air in the fuel line gives out a lot of smoke tighten up all those rubber connectors from fuel tank to heater or try a bottle of kerosene on a separate line and run at full temp to burn out the rubbish

That's nearly 15 minutes of my like I cant get back ,what a waste of time!

bad glow plug

Buy a cheap Chinese heater and get what u paid for
