I am having a problem with my Webasto DBW 2010 Hyronic heater
and wondering if anyone can provide an insight.
runs for a while, I get warm air from all 4 fans. Then at some point the heater "cycles" and the on/off green light goes off for about 5-10 seconds without me doing anything. When the light goes off, all fans also go off. Then in about 5-10 seconds, the green light comes back on by itself (with no change in the switch status) and the fans start blowing warm air but heating
unit doesn't run. This keeps going until fans start blowing cool air and this keep going on forever. The heater does never come back on until I power
cycle it on and off.
This heater worked for more than a year flawlessly and then I had a problem and I called in service
. After a week of troubleshooting, almost changing every part on it and several thousand dollars I ended up in this scenario. I will call the service
again but I am getting frustrated with it. I came to the conclusion that I need to start learning
and doing it myself so any hint you can offer will be appreciated.
