HI all ,
Truma b10 gas only water heater, sometimes it fires up but when temp is reached goes off with red light fault and sometimes does not even fire up just goes to red light fault, ANY IDEA ???
Battery voltage too low???? check the battery first for voltage. the truma will not fire up if the volts are low, but this also applies to other makes not just the truma, so check the battery and see what happens
