Truma Combi Boiler, battery less than 10V!
Has anyone else had a problem with the Truma combi boiler not starting up, the control panel states Operation error battery flat less than 10v.
Checked the battery with a voltmeter and it was reading 13.6v with the same reading on the back of the control panel and the connection to the boiler. It was working fine last wekend but was very cold in the van this week and dealer cannot book me in till
June!

sorry to hear your troubles, have you tried Truma direct? A mobile service engineer might do a quick fix?

Have tried disconecting at both the control panel and boiler with no effect, also contacted Truma who said it is something that it was not something that could be repaired by me and would need a dealer to fix which was not helpful. Just wondered if anyone
had the same problem so that at the very least I could point the dealer in the right direction!0 -

although you are getting this error, it would normally apply if you were running the unit on gas and the fan was being powered by the battery alone......and it really was low.
normally, when on ehu (i guess you are in hook up?) i wouldnt expect this error as the ehu (via a transformer) would be providing adequate 12v supply.
however, FYI.....
a fully charged 12v battery should read 12.7v.
the 13.6v you are reading is either across the battery but with an external charging device still on.....(ehu plugged in or solar panel connected).....or its the battery level but has not been rested.....for at least two hours...
so, it will almost certainly be the former, so you havent really determined that your battery is actually low...
.you will need to fully disconnect the battery, let it rest and then check later to determine its true state.
as to the actual error, cant really help much, try giving truma a call, they are generally helpful over the phone....im surprised by the reaction you got..
good luck.

Had same problem with my van two years ago, bought new battery hoping to cure fault, did not work. Went through various diagnostics over phone with Truma tech dept. In the end there are two pcb,s that had to be changed on the boiler itself.
GM, without any 'expert' input, that would be my gut instinct.
the error message is not consistent with the prevailing conditions.
to the OP, might be worth trying the unit on gas only, but i doubt it will be any better....
