Member Posts: 1
Hello I have strange problems with Buderus Gb022 HDU. It started occasionally to show 6A message , mainly when it started from being cold. Later it have started to be more often.
It helps when i block air intake around 50%.
I change gas block but it is still the same. After changing main board everything works fine. Do you have any clue whan can be the problem in main board?
What is 3 wire going to the gas block for ? thank you in advance
