Error E81H has become a persistent problem, we are away from home now, parked up on the driveway at our son’s house for Christmas. Error E81H has become worse, the Truma boiler is very difficult to restart, this morning we tried it 6 or 7 times without success. Finally we left it and went back in the afternoon and thankfully it did restart.

However, it didn’t restart in the night, so we woke up very cold. The Truma combi has become a real problem that is not going to go away. Another night and we will be heading home and I will investigate fully and see what needs to be done.
