I bought a batch of 10 atomiser screens and always replace them if I service the heater. I've since put in rebuildable fan motors to this one and my spare heater.

Thank you, I've become quite adept with these things now ;)

E-08 signifies 'burn issue' and I've since learned it has many causes, even low voltage. If it always throws E-08 and no other codes it's a process of elimination. Well done for finding your issue, that's another new one to me.

It was surprisingly simple to do and a really unusual cause of that code but does make such perfect sense I was surprised nobody else seemed to cover it. Thanks for the kind words.

The blockage was in the fuel inlet pipe so nothing to do with burn temperature. I think it was a result of the cheap supplied filter breaking and allowing dust and dirt to get in but not had a single issue since.

Thanks, I almost missed it but have since seen many others suffer the same issue.

I'm so glad you managed to fix it, they're not that hard to strip down are they?. Was it just throwing up an E-08 or did you get other codes?

Hi @@AMGMANIAC , I’ve never had anything but an E-8 code to be honest. The heater is a Vevor 5Kw one and I bought it just over a year ago to heat my large ( 23’x10’) shed so I could work in there in the winter, and electric heating was too expensive ! I installed it in January last year after watching all of John McKay47’s videos to avoid the common mistakes. It ran fine when used periodically from January to March last year and I ran it a couple of times briefly during the summer as advised. When I came to start using it in September it ran for about 1/2hr then showed an E8 code which turned out to be the pump had failed. I bought a new one and this failed after 2 days ! This was sent back to Amazon as I thought it was faulty and another one ordered. Again this ran fine for about 10hrs then that failed. At this point I contacted John in Australia and he suggested the fuel left over from March might be contaminated with water or something else. It turned out there was water in the fuel ( probably from condensation and also the internal metal fuel pipe had corroded. I replaced the tank with a small 5litre one and changed the filter and pump once more🙄 This worked well for about 3 weeks on and off then the E8 started again, sometimes the heater would start to shutdown, then fire up again on its own but only for a few minutes. In desperation I fully stripped the heater and I even replaced the glowplug, atomiser screen and casing temperature sensor in desperation, but this didn’t solve the issue. In the end I replace the control board today ( which came with a broken LCD screen but luckily my original worked with the new board ! ). Fingers crossed it’ll keep working now 🙂 What’s annoying is that the E8 error code covers a large range of possible faults, this makes it very difficult ( and expensive ) to sort at times !

@@mrfixitnorm4201 Yes it sure seems to be one of those codes with multiple causes. To cover myself I ordered another 5Kw heater so that I had any spare parts, it still cost less than £100, so was surprised when in my case it appeared to be a tiny blockage. I'm now once again getting E-08 errors myself which I can overcome by starting the heater at 8c and gradually increasing 3 or 4 degrees at a time until I reach 35c which seems to clear the error for a few days. I've also put an airline directly onto the fuel inlet nipple of the heater and cleared a blockage but it eventually came back. I'm going to strip it down again and replace the atomiser screen but it will be interesting to see what I find this time. Mine has been in for nearly 2 years now and being able to strip it down and rebuild it myself is a very handy skill to possess but I also like to hear the problems experienced by others to get a better understanding of the heater. Fingers crossed your woes are over and thanks for the detailed reply.

@@AMGMANIACI’m not sure if we have same heater. Mine is 7KW and I’m in USA. After summer period mine wouldn’t start with only 8C on the screen had to go all the way up

If its Chinese it will most likely be a 2kw or 5kw, check the label. I'd be interested to know.

Thanks, Rich. Hope you're well.

@@AMGMANIAC yes mate hope you are too,your van is looking brilliant you should be proud

@@Richbbieslifesadventures Thanks mate. Lots of things I'll be changing and upgrading, it's a steep learning curve ;)

Totally agree.

This was a strip down. When the heater was fired up the cover was on.

I have 3 dogs, we'd all cook if I ran mine at max. Running at full power will eventually give you issues but it does burn off all the residues. I've heard of people running at max before powering down specifically for that reason. As it happens my burn chamber has always been clean when I've taken it apart and I run mostly at either 25 or 8.

100psi from my compressor with an air gun attachment, getting just a tiny bleed through.

@@alexkruse312 I just used compressed air like you. Have you replaced the atomiser screen? That might be blocked with carbon deposits. If not you can replace that burn chamber section as well as the screens.

@@AMGMANIAC I tossed it in my wood stove to burn it out; that worked.

@@alexkruse312 glad you got it sorted.

@@AMGMANIAC haven't reassembled yet, but was able to blow air through after taking it out of the stove.
