Vokera 20/80 flowmatic fault?

gasmancometh · 26 Sep 2007

Please can anyone advise on the following:
DHW working fine, fan changes to high speed etc.
When C.H. switched ON, the FAN changes from slow to STOP! consequently the flame dies fairly rapidly due to no exhaust and then i think i hear a click (supposedly -lockout?

Please can someone HELP??

Try looking in the direction of the pump flow switch (bottom, back lefthand side).
From memory, which is fading! the only usual course of no low speed fan is a stuck pump flow switch. Then again it could be the PCB or any number of other things on a boiler this age.

probably the fan speed resistor, gold thing attached to bottom of combustion chamber, gets f***ing hot.
