Combi Problems

pompylen · 5 Jul 2005

My Vokera 80SP is still not without problems.
I get hot water and the radiators get warm but when the burners shut down the fan stops although the rads are not hot enough. I can rectify this by switching the Off, Summer, Rad, switch on and off a couple of times which starts the fan again and the whole thing starts up. If I don't do this it can waite up to 5 mins before deciding to start up again and never getting full room temperature. Any ideas Please!!

Thanks B.O.B, can I replace it myself or is it a job for corgi

I suspect more.

Almost certain the thermistor is common to CH and HW.

What is needed is in depth fault dignostics.

Where are you. I would start by getting the boiler serviced as per the makers instructions. Regularly do this in Glasgow (Vokera country).
