On start up only the pump will run.Fault lights 40 60 & 80 come on, indicating the fan does not activate air pressure s/w., but the fan doesn,t run on start up. The fan is in working order. Have checked DHW micro s/w,although problem is on CH also, .have checked for loose connections. Hoping someone will tell me it,s not the PCB.
