hi, baxi 80e gets up to full temp then shuts down,temp drops to 40 degrees and it fires up again until temp reatches 80 degrees then shuts down again.this happens continuasly as long as boiler is turned on,this is also causing problem to downstair rads which are luke warm and upstairs are hot,i have just replaced the temp sensor and safety thermostat and have just put in a new pcb.has anyone else had this sort of problem that can give me some advice,any help or advice would be greatfully appreciated.
