I have a Baxi Solo 3 PF 30/80 boiler with a slight fault, the pump will stay
on for hours after the boiler is switched off , I know its supposed to stay
on for a bit to stop the boiler overheating, but it stays on even when the
water its circulating is cold, it will go off eventually but a bit excessive
at present apart from that its working fine can anybody point me in the
direction of a fix or a decent plumber/heating engineer
Kevin
PS I have a separate valve for heating and water rather than a three port if
that makes any difference

I know a few in various parts of the country. However, as spread out
as these fellow trades may be there is a hell of a lot of the UK,
which means you would be better of narrowing down your location rather
than us all trying to guess where you are and happening on someone in
your area.

The pump not switching off is a fairly common pcb problem

I might have some in, I don't know

I had a quick look but I don't know which pcb I need as I have not had the
covers off the boiler??

You already said - it's a solo 3

It might not be on the website, it's the same as the solo 2

I was gong to say that if you get someone in the first thing they will
have to do is diagnose the problem then try to fix it. You can save
some money by trying to diagnose it yourself. Seems to me that the
pump is controlled by the boiler so like Geoff says it's probably the
pcb that's at fault. He fixed mine a number of years ago and it was
only 20 or 30 quid. If you get someone in they'll charge you for their
time and will probly either stiff you for a brand new pcb or try to
sell you a new boiler.

I just wondered if its the pcb or a temperature probe ??

Do you have a room thermostat or some other arrangement? If no
thermostat then it's possible that the pump will run all the time the
timer is on although the water in and out of the boiler shouldn't then
ever be cold.
I guess you're might not be wired up right.

The usual(?) series of events is demand switch goes on (i.e. external
thermostat), contol valves move to wherever they need to be, the pump
starts pumping, then the boiler fires up. When the demand is no longer
there the boiler stops firing and then some seconds later the pump
stops (and the valves.)

have a search in the Google groups archive for a poster here by the name of
John Stumbles - I think that he lives & works around the Reading area.

haven't seen him around these parts for a couple of months though.

this boiler is slightly different as it turns the pump on when needed and
the stats turn the boiler on, if all the stats turn off when the boiler is
at full flame it runs the pump which has a shunt between flow and return
until it cools down this allows it to be used in an enclosed kitchen
cupboard with no ventilation
