Hi

My central heating pump has started behaving strangely. I've tried to capture this in a youtube video:

http://youtu.be/2XCqdXgB0b0

If I turn the hot water on the pump starts to pulse. It runs for a few seconds and then stops for a few seconds. This happens for a while. Then it will often just carry on running fine until the tank reaches the correct temp. This happens are all three speeds.

Its definitely stopping rather than just running quietly. When its running it seems fine. The water gets hot, the radiators get hot when turned on.

Is the pump dieing? Or is there something else wrong??

Thanks
Alan

Do you really think that its not always done this?

I suspect its wrongly wired to the call for heat or boiler.

That is a good point. Two things have happened recently:

1. The controller has moved location due to kitchen refit.
2. Potterton EP2002 has been replaced with Potterton EP2

I still have the EP2002 so I'll stick that back on and retest. If that doesnt solve the issue then I'll get the plumber back to look at the wiring.

This pump has no water in it.

It is airlocked and just pushing the water up and 'see sawing'.

I shouldn't waste to much time with the wiring just yet.

:eek:
