Truma error 89

[Deleted member 38440]

Hello folks
Trauma panel shows error 89. Fault is both hot water and heater fail to work with any of the 230v electric options selected, the gas only option it works fine. This is fitted to an Auto sleeper 2013 reg. Phot attached. I’ve checked the fuse mounted on the pcb next to the Truma heater. Thanks for knowledge replies. Graham

We have a truma combi on our 2013 Swift, it has kept us toasty warm on many winter weekends and heated the hot water winter and summer. Only one minor problem when it would not work on electric last October and the thermal cutout had tripped, cause unknown, pushed the thermal cutout button back and has worked ever since.

If the above fails contact Truma their customer service is excellent.
