Truma boiler failure

[Stealaway]

Well
Last night the gas heating went off just before midnight.
It has been cold over night recently in Belgium.
I went and changed the bottles knowing I would need the heating in the morning.
This morning I switched the heating on and the fault code E507H was all it would do.
I have been trying a few things during the day letting it reset etc and now we have stopped for the night I had better try a bit harder.
I lifted the seats and checked as much as I could around the boiler. I found the over heat reset button under the connection cover and that seemed to reset it the boiler still wouldn't fire up..
Holding in this button down also sets off series of three lights flashing.
Eventually something in the boiler made a little chime .

That was it ---- all OK.

I really don't know what I did but holding that little brown pin in for 20 second seems to reset the boiler .

A bit late now, but is it the same as the photo below? The reset button [ grey] can just be made out to the left of the connectors.To the right of that is the little mini disco of three LED lights that blink on and off. I found when having to reset mine it was an indeterminate length of time required for the reset, but holding till your thumb really ached seemed to be about the right length of time, then the disco starts, and then you get that lovely reassuring audible triple click from the relays as the boilers readies itself for a restart.

Early this year I had a E517H fault code which wasn't a problem I had it before and had to press the brown reset button as above.
Our truma is underneath the fridge and almost impossible to access unless you have hands like a budgies foot or baby hands anyway managed to get to the brown reset button pressed it and it "popped off" along with the internal parts, shit gone forever and with no good access thought shit going to have to take the fridge out to access it to repair.
So sat and thought about it and thought I wonder if a total power down would do the same "reset" and it did by removing all power supply to the boiler job done

Even made a plan of attack for next time.

All the same, you nee to know what caused the fault in the first place.

In my case E517H happens when the gas runs out.

I have had the E507H fault code. In our case it was caused by being on gas heating at one site (no EHU used) then when we moved location decided to use EHU - plugged the EHU in without switching off the Truma unit or changing from the gas setting first. This must have upset the Truma system and triggered the fault code. Same as you - needed a hard reset to clear the code.
