Thank you all for the advice, I can see you have a very good knowledge of boilers and appreciate your help. I have managed to source a couple of sensors online for £8 each which is much better than jumping straight in with a new PCB! Will let you know the outcome. Regards, Gary

Tony, I never asked for an educational essay, just some advice. I simply asked for any other likely causes as to the source of my problem, which of course there obviously are. The too low max temp?? I reiterate once again, the max temp fluctuates!! It has been sitting at 42 deg for the last 30...

Yes, all three control knobs on the front face panel turn the pot on the main PCB. Please answer the question: "would a faulty spindle not merely prevent temperature regulation and not cause the fluctuation I describe?" I am not a heating engineer but have experience with electronics and...

Conflicting information? Which part of : "The LCD display on front never shows more than 50 deg when the heating is on and is around 37 deg most of the time but fluctuates up and down quite often." is conflicting? As I said before, adjusting the temp control makes no difference, it continues...

Well Tony, the likely cause is not the cause, the problem must be an unlikely cause then..... Are you a heating engineer with vokera boiler experience or just a keen DIYer? Common sense would point to the issue not being a faulty spindle (You say yourself: The spindle operated pots set the...

Yes, I know the difference between temperature and pressure, I meant to type temp, but wrote pressure by mistake. :cry: Can anyone advise any other likely causes of this prob? rgds, Gary

If it was the spindle, would it not just remain at a set pressure and not fluctuate from around 30 to 50 deg?

No, does not really seem to make any difference when i move the temp control, it seems to do what it wants! It is sitting at 38 deg at the moment. I have just selected min, medium and max temp. The temp never changed at all during the last 5 min. Thanks for the reply

Hi, I have recently noticed that my radiators were not getting very hot, even with the heating control set to max temp. The LCD display on front never shows more than 50 deg when the heating is on and is around 37 deg most of the time but fluctuates up and down quite often. The DHW works fine...
