Customer Question

Hi, I'm Phil.
I have a Potterton Netaheat 16/22.
I am having a problem in that it will fire up but never get to actually heating any water or radiators before shutting off.
If left for a while it will, once again fire up but, again, shut off before any heating is achieved.any advice?

What is firing - the pilot or the main burner?

Customer: replied 1 year ago.
the main burner.
I also noticed that there is water coming from the overflow pipe outside when the boiler stops.

If that is coming from the heating tank then perhaps the boiler is boiling the water?

Are you sure the pump is spinning? Try taking the screw out of the centre and seeing if the insides are spinning....
