Truma fault codes

[Lynne Roy]

Hi we have fault codes 515H and 638H on our boiler, they are not listed in the instructions, any ideas gratefully received, it’s freezing and we have 2 Young children sleeping over x

If you can read the flash code on the pcb, this may help

Fault No.: 0515 Flashing code:
Fault description: Combustion air motor speed out of tolerance 1.
Action: Replace combustion air motor kit

BUT all is not as bad as seems, it can possibly be due to 12v interuption befroe you shut down the Control panel.
If you can get to your boiler and do a hard reset by pressing (if you have one) the brown button near where the wires enter the truma unit.

Good luck, get the hot water bottles out.

It worked perfectly for 2 nights on campsite, just a malfunction.

It wouldn’t fire up with the fan on low, seems to have sorted itself. So many components on a new motorhome, we always expect user error and technical hitches. thanks for advice.

If the fault code is symptomatic of a combustion fan issue it could be that it is just "clogged" with dust \ etc. The cover over it removes and try tapping it and brushing out with a 1/2" paint brush. It's amazing the volume of muck that can come out of it!
Having said that, if it's new may not be your issue.

Thanks for all the good advice, happy to say we woke up cosy after setting the heating timer, maybe a slight malfunction or dust. Wasn’t too worried as I knew it would be sorted out by dealer if something was wrong.
