Truma 6E no Heating or Hot water on Electric

[Pete and Liz]

Hi All
We a have Truma 6E unit in our Hymer B698 (3 years old) and the heating and hot water don't work on electric , Gas is fine. No error codes on the panel, no red LED on the unit and mains to every where else in the van is ok.
I am suspecting its the elements or does anyone know if it could be something else?
Next question can anyone recommend some where I can get them replaced within a 30 - 40 miles of York or further if you have had a good service experience .

Thanks

Peter

It could be that the Combi 230v overheat switch has activated and needs resetting or the 230v fuse on the Combi mains power electronics board may need replacing .

Wouldn't I get an error code onto display if the 10-A fuse had blown?
I 'll have a look at the overheating switch , but we have never used it on mains in the 3 months we have had it.

On my last motorhome I had to replace that fuse several times. It was a very tight spot to get to. I had to dangle the fuse on a thread of cotton until it was lined up and then press it into space with a wooden spatula. I think I got an error code.

If this is the first time you have used 230v are you sure the 230v supply to the combi is switched on at the PSU or there may be a separate 230v supply switch for the Combi.

if the above are all ok maybe heater element failure. Had a 6e that had 2 heaters element failures until I realised the unit must have been dropped at sometime in it's past life, the core support plate didn't.. and the Ally heater fins were spread therefore no close contact with the element, suffered localised element over heating.

Hope it's something simples

Are you getting the small plug symbol on the bottom right of your truma control panel showing that 230v is available and are you selecting Elec 1 or 2 as a energy source?

Is York on North or South Island?

Is York on North or South Island?

Neither. But social spending is so low in York, I think it should be towed out to the Humber estuary far enough to qualify for foreign aid!

Hi All
Thanks for the responses .
Yes I get the plug symbol on the display.
Yes its no heating on EL1 or EL2 so they are both dead.
And we are south of York , Pocklington to be exact .

 

[Pete and Liz]

Update
Removed the boiler , not and easy job but took it slow and steady and it took 1.5 Hours. Tested both elements and found them both open circuit. I removed them by drifting them out with a small bar and soft mallet. Ordered some copy elements at £132 as I figured as the genuine ones only lasted 3 years and have only been used on about 10 occasions in that time so the copy ones can't be much worse and at 60% cheaper they are worth a punt.

If you have not used it on mains and you need to pay someone to fix it probably not worth bothering getting it fixed. It will cost a few hundred quid, also it's cheaper to run on gas than pay for electric.

We are on our 3rd Hymer our Truma's have always been gas only.

 

[Guigsy]

We've got a 6E. I thought it was broken the first time I used it. It's extremely slow to heat the water. Even on EL2 on full heat, it takes about 20 mins before I can even start to feel an increase in temperature in the water. If I'm on hook-up, I'll leave it on full all night if we want hot showers in the morning. And even then it's best to switch to gas if I want it to remain warm while taking quick ship showers.

 

[Pausim]

The electric heating is only two 900W elements, totalling 1.8kW. The gas heating is 6kW. If you have refillable gas and are on a metered EHU use gas, not only is it far quicker it is great deal cheaper to run. In a few years time I think unmetered 16A site electricity will be history.

I've also found that it takes a good 45 mins on EL2 to get the water up to HOT. Mind you, it is "hot, hot, hot" when it gets there.

I am surprised that both elements have failed.....at the same time. And with so little use. I suspect something else might be going on.

I was surprised too but I did a little digging on the interweb and spoke to two mobile caravan/Motorhome fitters and they were not suprised and have attended a couple failures when the units have been just out of the two year warrantee. I did a quick check over the PCB and there of no obvious signs of overheating components ,checked the diodes and resistors and everything appears to be ok. TBF there are not a lot of components on the board.
If the new elements fix it thats great but if they don't I will just live without the electrician stick to the LPG.

I can accept that AN element may have gone - but why two separate elements at the same time?

Ours have just both gone at the same time. Or perhaps because they were so slow we didn’t notice that they actually went one at a time. But we’re now running happily on refillable gas, in Europe where, so far, all the EHU’s are metered. As others have said, I CBA to fix it.

Just for clarity I never said there went at the same actual point in time. One could have died a while a go and was not noticed until the second failed , just that both are totally dead now.

 

[Pete and Liz]

Update
New elements fitted and boiler squeezed back in to location with only minor scrapes and loss of skin. Just for ref the resistance of a working element should be about 58 ohms my eBay versions are 57.4 so fairly close to giving 900W each. The electrical heating is now working fine . Not as quick as the gas for obvious reasons but faster than I thought though.

used to come across this scenario all the time when i was a working plumber what normally happens is one element fails so they turn it to the second one and because it now works they don't replace the broken one and then cant believe it when the second one fails
