Hi Everyone,
My Combi 105e has just developed a fault with the CH as below.
When the CH turns on, The pump and fans start as normal and the Burner ignites. The flame then dies down within 5 secs, and the boiler shuts itself off and repeates this cycle.
This doesnt happen everytime, and if and when it doesnt happen the CH works fine for a while, until the burner goes out. At the point of relighting the above fault *can* re-occur.
I have no error codes shown at all
The DHW is fine, and when a tap is turned on the boiler stays lit.
Im thinking it could be one of the following?
Flame Sensor (I pressume this would effect the DHW as well though?)
CH Temp Sensor (wouldnt this just kepp the burner turned off rather than cycle?)
PCB
Has anyone seen this type of fault before who can give me any advice?
Thanks in advance!
