I have a Potterton Suprima 30 in a five years old house. Last year the PCB had to be replaced due to the system constantly going into lockout.
6 months after the (not cheap) PCB was replaced, the Boiler is acting up again. The system randomly goes into lockout, but the reset button sometimes works, soemtimes doesn't.
Another strange symptom that has started happening a couple of times is that the Boiler has on a couple of occasions come on all by itself late at night when the heating and hot water timers have not even been set to be on.
Also, the redirector (i think that is what it is called - it is the little black box under our water tank) occasionally makes a buzzing noise when the boiler should be on but won't come on.
Today, I cannot get the boiler on at all. Pressing reset on and off all day has done nothing for me.
Can anyone advise what to do please? Am I looking at another costly engineer visit?
Thanks
