FIX TRUMA COMBI 6 E FAULT CODES E638H & E515H | Broken motorhome/caravan heating

In this video, we show you how we fixed our broken heating.
As we were preparing to leave for a weekend away, we realised the heating in our Roller Team Auto-Roller 707 motorhome was not working.
The control panel alerted us to 2 error codes to do with our Truma Combi 6 E boiler: codes E638H (Speed or power consumption of the combustion air motor is out of tolerance) and E515H (Combustion air motor not rotating).
We talk you through some steps you might consider taking if you have similar issues.

[@WillMerrick-th4do]

Thanks so much for this. i had done all the resetting but twiddling the fam looks like it might have done the job for me. Thanks for pointing me in the right direction

Thank you, great video, e638h , it worked for me. 😅

This video is really helpful. We had the codes this morning. I took the fan cover off, it was full of thick dust. Cleaned it off & the boiler is working (for now!) the errors have cleared. Did you end up needing any new parts ?

Great to hear it was helpful. No, so far it's been working fine and we haven't needed to do anything else (touch wood).

Probably its ball bearing is failing. I'd buy a spare just eventually so that I don't end up without heating and hot water in the middle of nowhere :)
