Mend BAXI Heating Boiler Dhw

BAXI COMBINATION BOIER?

BAXI COMBINATION BOIER

Power on
Presser gauge shows 2.5
CH and DHW mode
Boiler star going
Pump start
Fan does not come on.
I checked fan Terminals, there is no power there, when demand is on.
I checked the micro switched for DHW and CH both makes the connection, but fan doesn’t come on.
I manually make the Micro switches still fan does not come on.
Can you help please?

Possibility- Look for a manual reset button on boiler- P.S. 2.5bar is too much and could possibly cause problems in the future. drop it down to about 1.5bar by letting a bit of water out of the rads.

firtly the water pressure is too high (should be 1-1.5 bar when cold) bleed excess from a radiator (do not use the safety valve!)

you said you checked the micro-switches, and say they make, assume you also checked the switch with a mutlimeter to ensure they are working too, and checked the voltages reach the pcb terminals...

would be suspecting a pcb fault if all checks out
