A trivial question from a newbie: I'm getting an E632H error on our Truma control panel. It's not in the manual but a google search suggests that a physical switch needs to be reset on the boiler. Given the pandemic, we had no detailed handover from the dealer so could some kind person save me some time when it's light tomorrow by letting me know where to find the boiler please? Thanks in advance and apologies for a trivial question.
