Truma combi cp plus
Hi.
We're having trouble with our truma combi cp plus boiler. For some reason the 230v went initally which was replaced which we attributed to a power surge on a site we stayed at and then a few months down the line we get another error code, turns out the circuit board needed replacing which according to truma never happens. This was replaced recently but again, an error code has just popped up and we think it's the 230v amp again! Our caravan dealer has ensured us that they've checked all the wiring so why does this keep happening? The boiler works fine on the gas for both the heating and water. It's so frustrating, this is our first caravan which we've now had for just over 2 years and feel very disappointed. We feel like we're doing something wrong but we've been through the start up manuals to double check and can't see that we're doing anything wrong. Any help would be gratefully appreciated as to why this is happening, surely caravanning shouldn't feel this disappointing 😠.
