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
