We are currently parked in a pub carpark which we Are staying in overnight, we aren’t on hook up, we are running on gas and we have an issue with the heating, the error code is E517H, the fridge is working fine on gas.

It is a
Truma CP plus controller with lcd display
Truma Combi (E) Boiler


We have a full gas tank, as it was recently filled and the display lights show as such.

We tried turning everything off and then turning back on, started the engine, but nothing is clearing it, does anybody have any idea as to what to do to clear it and to get the heating working?
 
Hi, we had similar problem with same boiler after changing gas bottle. There is a reset button on the boiler. Try that. Sorted it for us.
 
All fixed (for now). There is a fairly elaborate Truma reset procedure. The E517H is a gas fault but the exact reason is not specific. After waiting for 15 minutes I was able to clear the fault code and the heating and water started heating. Mark

Might be worth contacting Truma, the error codes published sometimes do not contain full information
For example, we had error code 18 a few times. The fault code refers to blocked air outlets or blocked inlets.
We had none of these but the fan in the boiler seemed to be running faster than normal, so we contacted Truma. They told me if there are no blockages, the code refers to the fact the boiler is entering a cool down phase.
We ignored the error code next time it came up and it reset itself.
Hasn’t happened, or we haven’t noticed it since.
 
Hi,
I had exact problem with a new Pilote, tried and tried but nothing, it was going back for some warranty work.
Apparently you need to ensure the gas is on prior to switching the controller on as it checks for gas pressure first and returns a fault if undetected, then as you say wait 15mins before you can try again!

Currently in Germany, with the dreaded E517H error code, which caused me to wake up to a stone-cold van this morning, in a balmy 2c Stuttgart!
Electric (coin operated meter) ran out at some point in the night, (I only had 1 x 50c coin...don't ask!) and the heating was on MIX. Have tried the reset procedure, including the 'hard' reset on the boiler unit itself - no joy. Noticed gas flow was diminished when both gas rings selected on, so suspected low LPG. Replenished GasLow with approx. 6.5 Litres of LPG (first time filling up since fitted,) and it seemed to take ages, about 10 minutes to fill just over 6 litres - is that normal? I'm sure the GasLow isn't full, but I gave up after 10 minutes on a very cold service station forecourt. GasLow valve was OFF before filling (as recommended.) Currently on WoMo site in Sinsheim, (decided to seek out a place with EHU just in case...good job, read on...)
Gas rings are fine since replenishing LPG, full, strong flame on both. Heating will still not work on gas, (and initially didn't work on EHU, which was a heart-stopping moment, but ok now.) Is the problem temperature related I wonder? EU LPG has(?) a mix of butane/propane to deal with low temperatures I think. Unless I can fix the problem, I need EHU for heating to stay comfortable for the next 12 days.... Any ideas out there please?
 
Cold night again Pete, or have you got it up and running? 🤔

Looking on the Sunlight website, there are plenty of dealers around in Germany. (y)

We had an interesting scenario over the weekend.

Had the heating on running at 20'c when we were in the van 14'c at night. The wife put the hot water on for an hour when we arrived, it never went on again and the water temperature stayed at 55'c all weekend despite us using it constantly for washing up etc.

Truma app and the control panel both showed water heating off.

Has me somewhat worried as the Truma website and handbook say you can leave the heating on (water heater off) with no water in the boiler.
 
Yes you can run the heating without water in the boiler.
If there water in the boiler the water will heat up if the boiler is set to heating only, it just takes a lot longer to get up to temperature.

So.... after discussing with Martin from GasLow, who kindly rang me this morning after I had emailed them last night, and some rudimentary diagnostics, a failed regulator was identified, (the gas rings failed to light this morning too, luckily I carry a small Camping Gaz cartridge stove, so at least I could brew up.)
Off to a place about 30Km from here, and €70 later, I have a new regulator fitted, but not connected to the GasLow, as none of the German fittings are compatible, and cannot be sourced in Germany, apparently. So, 1x 5Kg bottle of gas from Hornbach (~ German B&Q,) and I'm back in business, the van is nice and toasty as I write this - all receipts kept, plus dealership informed that I will be reclaiming everything (and having the new regulator fitted to the GasLow,) when I'm back in UK.
3 days in, 11 more to go - I wonder what's next??

I thought the Gaslow fitting were the same as the standard German connections.
