HELP ! Having problems with my Truma heating. When I run the heating on combined gas/electric I get an error code come up after about 30 to 45 minutes. The boiler then blows cold air for ages and I have to wait for it to cool down before I can get heat again. The heating (cabin) temperture is set at 20 degrees. The error code is W401H which when I look it up on the Truma site it says water is overheating. I do not have the water heating on at the same time but the water is extremely hot. Could it be hot water thermostat? The boiler is well vented, hoses and breather pipes all appear clear. It’s only had a few days of use since new 3yrs ago.
