I've been a pressure washing contractor for 23 years. A few tips for your machine; Bypass the break tank under the unit and plumb it to a garden hose with an inline water filter. Put a male and female guick disconnect on the pressure hose so that you can easily remove the wand from the hose. The valves you pulled out are called check valves. They get clogged open usually not allowing the pump to build full pressure. Pick up a bag of viton o-rings for the QDs. They wear out regularly. Your burner should not come on unless the trigger is pulled open, if it does you have a bad flow switch and that dangerous (steam explosion)!. Always run water through the system before and after running the burner. The shrader valve is probably to blow the water out of the pump and coil, better to fill with antifreeze if it can freeze. The braided hose is a pressure bypass line. When you let off the trigger it recirculates the water through the pump head so it takes pressure of the coil, hose gun. After 2-3 minutes in recirc. the water will get hot and can damage the seals in the pump. Make sure you have the correct tips in the wand. According to the gpm of the machine. You will need a low pressure soap tip with a single lance wand, it uses the venturi effect to draw soap but its always best to have the draw hose after the coil so your not running chemicals through the pump or coil. You can run diesel or kerosene in the burner tank and your right about it being like a home oil furnace. Beckett makes most of them. Good luck and be careful.

I spent a few years repairing these, it must be set up so the burner only runs when water is flowing. Otherwise you quickly end up with a very large steam bomb. There is a vacuum switch i saw it on the unit but its not working right. I know its a video but before you run it again..please get that part fixed..id miss the sunday morning videos. Edit im 49 minutes in maybe you do fix it by end.

Another great fix without a manual , you have a very great sense of deductive reasoning , great intelligence and a pleasure to watch . Thanks for the video's you produce !

Might get a lot more pressure if you continue cleaning those valves in the pressure pump that were stuck closed. Probably a multistage pump that needs them all flowing to create max pressure.

Possibly the first-ever pressure washer that puts dirt onto the item you're trying to wash. :)

i used to work on these pumps and it looks like a interpump pump. when you seen the water dripping from under the pump from all 3 of the pistons it means the piston seals are worn and need replacing so you get the full pumping capacity, the pistons are ceramic and the seal acts similar to a regular piston ring but is located in the bore and not the piston

The Schrader valve is for blowing air into the coils so it doesn't freeze residue water in the coils in winter. I'm thinking the seals on the pump valve might need repacking.😊

Another demonstration of advanced diagnostics. There is not a chance I would ever dive into such a project; I guess that's why it's so fascinating to see someone who would. Amazing video, as-usual Mustie.

I found a Alkota hot water pressure washer at a metal recycler. 4000PSI @ 4GPM, with a 18HP Vanguard engine. After cleaning the rust out of the coil with acid and replacing the burner motor, igniter, unloader valve, muffer, and rebuilding the water pump, it works beautifully. Overall, I spent about $1000 for a unit that probably cost $12 - 14k new.

We used this kind of pressure washers at the family winery to wash out the fermentation containers. I fixed them all the time. We had hard water and the minerals would collect along every interior water passage, especially the heating coil. Clogged like crazy.

You need to make sure the burner doesn't run unless the water is flowing out of the gun. It has the potential to be a pressure vessel. The silver box you referred to as a pressure switch is a vacuum switch. It should be wired in series with the fuel solenoid so every time you let off of the trigger it stops solenoid from energizing.

Good score that one Mustie, the fuel filter is a baldwin B825 and the upper valves are the outlet valves so should not stick on you. The soap intake usually drops the pressure slightly so with it turned off you should get a better pressure, I always run the cleaner with the heat turned off until i can comfortably hold my hand on the steel part of the wand, this only takes a minute or two and cools the heating coil down enough to not cause any thermal shock if you run cold water into it

Always a good feeling when you fix something, and bring it back to life.

Awesome as always.Thanks for sharing and taking us along

That thing works great now! I build race engines and use a spray wash tank with heat, but I’ve always wanted to try the hot pressure washer for pre washing the nasty engines that come in for rebuilds. Good job and awesome find! I’ve been watching your videos for years and will continue watching!

Another nice win, I love to watch you figure out machines on the fly! Thanks for the fun.

Yet again, another in-depth education on something I didn't realize I needed an education on. NOW, I need one of those things! Thanks Mustie!

You had the best explanation of GFCI I've ever heard. Thanks for teaching me something new!

The lift at the end. I still remember you fixing that distributor. It was a brilliant video. Thank you.

Thanks for the shop time Mustie1! Great save on the washer! Steam cleaning is handy to have.

Definitely not a bad deal for just 3 stuck intake valves. Congrats! In case you don't know, look into getting one of those rotary tips with a fine point on it. They work amazingly well for cutting through grease and nasty stuff.

Those are nice machines! Can't wait to see what happens!... EDIT:... Nice save!! Definitely worth the time and effort. Thanks for bringing us along! J.W. in Mass.

Nice score and no personal injury getting it going!

Pretty serious machine ,and another great repair !

Yet another great job. I would have had no idea whatsoever where to start.

Uggg seeing that skid steer all covered in oil and a perfectly good cleaner, driving my OCD crazy, I must see it cleaned! Thanks for another great video.

You just have knack of bringing all kinds of things back to life there Darin. Very awesome video like always my friend.

The 90 degree angled nozzle looked home made. I hadn't seen that before. Thanks for the cool video.

We used to have an industrial Karcher diesel pressure washer at one place I worked at. Every now and then we had to run some descaling fluid through it on hot wash when the pressure began to drop noticeably. Also, try to get the thermostat sorted too, as it is its more of a paint stripper than a hot washer. Gr8 vid 👍

really pisses me off when people watch for 5mins then stop and start making comments,do this do that.If they would watch the whole thing first they would see he covers 99% of what they are telling what to look for

That was a great find at that price and lucky that it was just a few stuck valves. I'm currently looking at getting one myself, fingers crossed I get as good deal.

You are a man after my own heart, operating a steam Jenny with short pants. You the man.

For a little added security for your shop...park that forklift tight across the inside of the garage door! Will wake some thief up if they decide to ram the bottom of the door to get in.

I'm glad the pump wasn't roached! Fun to learn about a new kind of machine!!!

I have no idea what is going on in your world, but it is great to hear you laugh again. Keep up the good work.

The "tire valve" is for blowing the water out for winter storage. You need out flow for the pump to engage.

Thanks mustie another happy Sunday 😊😊😊😊

I have an alkota machine. I use the air chuck to blow the water from the coil so it doesn't freeze up in the winter.

That fork lift looks like incredible! powerful and sporty too!

Great find!

Awesome save on the ole steam cleaner...used one back in Auto Shop back in highschool and it always made quick work breaking down the old grease and grime. Like that for a small investment and a gamble..you got a machine that will serve you well. Bravo at bringing it back 😁🇺🇸🛠️😎

This turned into ASMR power washing at the end and I'm all for it, nice save!

Good afternoon everyone watching from Lincolnshire UK 🇬🇧

Mustie if you get tired of burning your hands on the wand do what I did back in the day, I took 2 1x2’s the full length of the wand and carved a groove 1/2 the diameter of the pipe in each and hose clamped them around the wand, I shaved corners off the boards for comfort, great video keep em comin

Mustie1, Excellenteeeee!!! Nice purchase and amazing fix. Thanks for the video!

Nice job. Thanks for sharing

👍👌👏 2) Great purchase again. Congratulations 🎉

I worked as a detailer in the late 1980s and used a kerosene powered pressure washer. It was a labor saver for sure.

Great resuscitation!

Used a Hotsy brand hot water pressure washer for years in a meat processing plant. It made cleaning up at the end of the day so much easier. You did well with this purchase.

Im sure many of us in the mechanical trade used these hot water washers, as it was usually the bottom rung of the ladder, as we learned our trade. Id say, [ without watching all the way through, ] that you don't have enough pressure, so the pump needs an overhaul. But i have fond memories of my early days, learning the ropes. Thanks for this one, brought back some happy memories.

I used one of these when I was working as a farm hand to pressure wash the tractors at the end of the year. Ours had a gas engine instead of electric but still used diesel for heating the water. They work really well when trying to remove grease and oils!

This was a fun adventure to watch, LOL! I bought a different brand at an auction and it had the same problems. Once we got the wiring put back together we discovered it had probably been used in the oil field in Oklahoma since the heating coil was completely plugged up with what seemed to be bentonite. We took a 3/4 drill and some 3/16 cable and used it to auger out all of the clay, rebuilt the pump, got it fired up and it worked great. I recommend Stabil Pump Protector when you're going to let it sit. It keeps the corrosion out of the pump and displaces the water for cold weather.

Mustie 1, I know absolutely nothing about these machines and I don't need one here in S.C. but, that was so cool to watch. God bless and stay safe.

The steam genny you purchased was a super bargain. I used them in the past in a Diesel engine repair facility. It would make the most greasy engine or surrounding frame squeaky clean and then a pleasure to work on. Nice video as usual.

I really enjoyed that. I've been finding a lot of use for my little Ryobi pressure washer but I dream of having a gnarly degreaser like the one you just repaired. I was super nervous when you put the impact gun on the valves.... Thanks for showing me how to do it.

Glad you bought this Darren. I bet the lady who sold it wished you worked for her.

FYI, burning kerosene, especially on a machine that sits quite a bit, is a much better plan. Unfortunately, it’s expensive and not as easy to find. I work on these things for a living and it’s extremely rare for a kerosene burner to need anything more than the most basic service. Additionally, make sure your nozzles are properly sized, otherwise, pump and unloader valve damage can occur. Hopefully I don’t feel stupid after watching the video and find out you already cover this stuff. Ha.

Wow! Fire, electricity, water and high pressure steam. You outdid yourself this time. Be careful!

nice score with the hot water pressure washer Mustie. they are worth their weight in gold. bit temperamental at times but once you get the hang of their quirks, they arent too bad. you are on right path - descaling the coils. oughta help get rid of the muck etc

You Scored big on this one... You're gonna love having that thing around

You got that machine for a steal nice you got it working, I bet that would come in handy for so many cleaning projects but especially for cleaning motors and oil of the bottom of vehicles.

Thanks for another amazing video.

i love your ramblings and bad jokes' keep it up mate.

Love your channel Bud ! Great variety....I like your other friend who saves REALLY rusted VW's He does NOT know the meaning of Give Up..Love that.Thanks for entertaining Me

The gamble pays off! Nice machine well worth investing a few dollars to make it a long term shop tool. This will bring clean up to the next level.

Awesome barn find. You now have a bargain steam geni. Congrats

You will get a lot of use out of that. The hot water makes a lot of difference when cleaning. Good video, thanks !! The one thing I saw is when you went to put the tip on with your finger on the end. You quickly moved it, which was a great idea. I've heard horror stories of guys injecting themselves with water, left over pressure in the hose.

Never sell it. It is incredible tool to have. It takes off mold from anything, Washes interior parts and seats . And for washing greasy engines , there is no comparrison with the simple preassure washers. We cleanesd the production floor of grease production facility with one of those , it is so good of a tool.

In high school my friend had a job cleaning a slaughterhouse every night after school from 3-6pm. He used a similar machine to clean every service in the slaughterhouse. They also added some kind of cleaner/sanitizer. It was a very hard job, but back then it paid twice as much as retail jobs the rest of us had.

Seems to work fine as the pressure goes. Amazon sells a pressure gauge that you can hook up to the hose fittings. 3/8 size is the hose and 1/4 is the fittings size. I just replaced a cracked ceramic tube in the pump on a pressure washer i got. Went ahead and rebuilt the pump while I was in it but yours is fine. They get dry and will leak. Ive also filled some up with oil where the water inlet is and let them soak for a week. Works good for winter storage as well. Great content Sir.

Good Morning Mustie! Another interesting video on another interesting machine!

great change of venue's thanks we all learn together

Id say that was a good purchase. Nice work on fixing the intake valves which was probably the main issue.

I would be cleaning everything with that! Great find!

I got one of these for free. I don't know if it works or not as I don't have 220 in my garage yet. I'm glad you found one so I can learn how to fix mine.

Looks like it was a easy fix and a great gift for your collection …..

My company, HOP Sales & Service was the original seller of this machine (blue & white decal on the side). This is a mid 1980s model. Great unit, though. We still carry all the parts for them. Nice work on the diag / repair.

That is an awesome looking hot water pressure washer.

I must admit I was a bit nervous for you as I watched you troubleshoot this unit . I worked for Alkota in the late 70s and years ālater I was a mechanic for an outfit called Ben's Cleaner Sales in Seattle WA . The owners that started Aladin all worked for Alkota prior . The only thing I did not see the other experts mention is that if you want a more trouble free burner , run stove oil . Kerosene does not put out the same BTU as stove oil with the same size burner nozzle . The other thing with kerosene is if you run out , it has very little lubrication so you can damage the pump easily . Diesel #1 is a good second choice , #2 can soot up your coil . I would say a good buy .

I have to say my first reaction to a GFI trip is not to ignore it and then touch metalwork that could be live. Lol. Maybe I am getting soft in my old age. Done the whole 'being thrown off my chair by electric shocks' in my early years. 😅

Looking good, made a bargain, thanks for sharing.

sweet deal...you always seem to find good deals

Your pump is at half power. Free the other 3 valves.

Another excellent video

$300 and it now runs fine. ..... That sounds like a win in my book.

Nice find!

Thank you for sharing. Nice.👍

Used to service permanently installed versions of that years ago. Drove 3hrs to service one, in a brand new fleet van just picked up, got all filters changed valves clean, pressure reset etc. Switched it on to test it using the van as a test vehicle. Blew the paint and filler out of the front wing! Turned out it had been bumped and repaired by the dealer. Cost them a new front wing and 2yrs free servicing 😅

Great video mate you saved it 👍

That was a great deal, even if it was a bit of work to get it functioning properly. Definitely gonna come in handy for de-gunking some of the relics you get in there!

well trustie mustie another great fix great vid mate

I had one like it and it was a very good machine, never had much trouble at all and it was simple to keep working Wish I had never sold it 😊

It's been mentioned that the burner MUST shut off when you release the trigger and no water is flowing because it will quickly heat up and has the potential to become a bomb. The inlet valves often get stuck with rust, the outlet ones get forced open by pressure so don't suffer as much. You can also get bits of debris stuck in the inlet valves stopping them from closing and allowing the pressure back into the inlet pipe. Running the pump without water flow will burn out the pump seals, these have (normally) ceramic sleeved pistons running in seals which will leak if they get worn and water drips out of the holes under the pump. When you let go of the trigger the pressure builds up quickly and opens the valve allowing the water to bypass back into the tank. If there is any air in the system this valve will hunt as the pressure drops and then as pressure builds again the burner will start for a second or two. It's likely that the burner doesn't fire up properly but will squirt fuel into the bottom of the boiler so you can get a build up resulting in a fire. If I remember correctly, and these machines arelikely 70s rather than 80s, the burner nozzle would be about 1.5 0r 1.75 UK gallons per minute, Check the filter in the pump and behind the nozzle as they can block, yours burns cleanly so should be ok. Run it on cold only for a couple of minutes after switching off the heat. More modern machines switch off when you release the trigger rather than allowing water to bypass which is a safer and more economical method. High pressure hot water on car paintwork can cause damage to the paint so it's better to keep away from the bodywork and use the approriate chemical/soap.

great machine, you could put a manometer where the shrader valve is so you can see what pressure is making. also if you can find the parts: piston seals and valves will go a looong way for you. you got really lucky that the burner part of it is in god shape, they are a pain to fix

Another fine product repaired by the 1

That was great like they all say if any one can Mustie can thank you for sharing and your time was really great never miss a video and can't wait for next video thank you

Great job, yes the heat from the steam will rejuvenate plastic, you can do the same thing (carefully) with a heat gun. 👍

That is a very useful machine Mustie, I can see you cleaning up all those greasey machines before you start work on them. I suppose the only downside is that you will have to relubricate everything to stop them corroding.

Buy a good quality descaling acid and add some to the water supply reservoir, run the machine without a nozzle on the lance until you start to see black sludge appear. Once you see that sludge let the machine sit for a day to allow the acid to work. You may need to remove the low and high pressure valves when you flush the system. Also reducing the water flow using the pressure valve will increase heat if you are looking for wet steam.
