Potterton kingfisher boiled water then rads packed up

[Charley7]

Water boiled. Plumber fitted new thermostat and circuit board. Then radiators stopped working, downstairs first then upstairs.

Pump?

Pump?

Plumber said pump working. Hot water going up pipes. Poss not going at full whack?

 

[Charley7]

The upstairs radiators had been working. He turned them off to try to force the water through downstairs but didn't work. When I put upstairs back on they didn't work either.
The plumber had also given the pump a 'tap' to encourage it.

Change the pump

 

[Last Plumber]

Is it an SMC pump?

 

[woodsy]

As above, pump sounds like the most likely culprit.

 

[Last Plumber]

I think if he give it a 'tap' it will be an SMC. I think ( as the above others do) that it's stuck or sticking.
Change it is my advice. A good heating engineer will be able to diagnose the problem onsite for you !

Change plumber (& pump) if they can't work this one out they aren't trained !!
