thank you Tony, the PCB was changed around 2006. boiler is Suprima 50. not sure if the PCB is a newer version of PCB. how can I find out what version of PCB?

good news: my boiler has started up all of sudden by itself and it is working both HW and CH. for now it is working. so there is hot water tonight . thank you all. wonder what has caused the boiler not firing until now. will try and call an engineer to have a closer look at the boiler.

what is the going price for a PCB ? also the outlet valve of my pump is leaking (visible green discharge). how big is this job? do you think if it is worth replacing the valve at the same time of having PCB replaced?

[/url] thank you for that picasso.

thank adlplumbing. from this forum, it seems that PCB model 5111603 is popular one. is this still latest model. which model should I look for?

very useful information. thank you again yes, I will look and see if they can help. would it be advisable to have potterton specialist to replace a PCB or parts?

thank you picasso. definitely dont want to make things worse. PCB was replaced about 4 year ago. where/who would you recommend should I call to get it replaced?

thank you bengasman for your quick response. your comment noted. there seems to be *no* power to pump while the light flashing. it does not spin by itself. is this correct? I pull out the bleed pin toward me and i can turn the pump.

good evening, my suprima 50 has developed a fault that its reset button does work any more. no hot water and heating. when I opened the boiler cover today and noticed that there is a slight damp in the flue fan resister. not sure if this is the fault. I would appreciate if you can help...

just an update: Before trying to test the pump, I tried the reset button, the boiler fired up and was working for a few hours. however it now locks up again. the reset does not seem to work properly. it seems to me the pump is working. could it be boiler or PCB is faulty? still...

OK Tony, I will do a test by connecting pump to a socket. do I need to swicth the HW or CH on to test if it can turns ? it does not make bussing noise when the amber light flashes.

that does not sound too good. thank you as always. will look for a new one. but is there anything that you think may be worth of checking before buying a new one?

good morning all. thank you Tony, yes there is a black plastic knob. I have tried unscrewing it and pulling it towards me. but I did not see it turning though. also its completely cold. does it mean there is no power to it ?

Hi Tony, the pump does not feel hot, it is of normal temperature or in cold while the boiler is on calling for Hotwater and amber light flashing. the pump is BG multihead 11.

thank you Tony for the advise. I will try the FAQ

unfortunately, I don't have one. anything else may be of use?

ok. thank you for that. could you please show me how to do a proper check on pump ? I have tried loosening the bleed screw, the water coming out is black color.

just check that my motorised valve is working ok.

good evening, my suprima amber light keeps flashing when calling for hotwater or CH. press reset button does not work. the amber is solid when CH or HW is in off position. it is sealed system with a hotwater cylinder. the pcb is about 4 year old, a replacement. I guess that it is a...

many thanks to you all for your replies. I certainly shall try it out on the radiator this weekend. Would it be advisable to add any anti-inhibitor into the radiator while the radiator is open? If so, what brand and how much can I add? At the moment, the clear water is coming out of...
