I've got a Buderus GB142 boiler. It was giving a 6A error code, and shutting down. This means it is not detecting that the burner fired. After checking both the ignitor and flame sensor, and finding the ignitor glowing, and (I did clean the flame sensor, but it didn't help), the only other thing other than the forced fan induction is the gas valve itself...so, while it was trying to go into an ignition cycle, I tapped it lightly with a ball-peen hammer and it lit up.
So, after all of that, would the next thing be to replace the (apparently sticky) gas valve? I don't think that there's any serviceable parts in it. It looks pretty straight forward (I do have the maintenance manual).
The thing is 11-years old, so it is out of warranty. I think I read that the newer gas valves also require a circuit board to be replaced to match its new characteristics. I can try to call them tomorrow, but was wondering if anyone had any other thoughts. Don't want to spend money I don't need to.
At least it's heating up and I should have hot water for a shower in the morning if it finishes, even if it doesn't want to fire up again on its own...the tank's big, and well insulated. This all became apparent that I had a problem when the shower wasn't as warm as it should be, and I couldn't change the temp with the control.
I thought that it was probably the ignitor, since they don't seem to last all that long, but this one is working. These things always seem to happen on the weekend, and being frugal, didn't want to call someone out. Luckily, my condo only has two outside walls, is well insulated, and the other walls to adjacent units kept the place decent, but without hot water. It wasn't all that cold for this time of the year, either (around freezing).
