Potterton Profile 60E shuts down

[MSimmo64]

My Potterton Profile 60E will not stay fired up. I noticed I had no hot water or heating (luckily its currently summer) & the boiler was not fired up. Feeling the boiler casing it felt warm to indicate it had been on. So I switched the controller to constant & whacked the room thermastat up to see if the boiler would burst into life. Nothing happened. My boiler guage was set to 5, so I moved this up to max. Shortly after the boiler burst into life for roughly 60-90 seconds then went off. I left it for a day whilst I sought advice. Tried again next day, pressed re-set button underside and shortly after the boiler fired up again. Hooray! Ran again for approx 2 mins then cut out again and no life since. Changed PCB approx 3 years ago fror a re-con one. Thought about changing this again. Any ideas please?

It could be a circulation problem.
Make sure there is water in the system and that the pump is running.

I will check this out. I have recently had some gurgling noises from the pipework in the loft, could this be air? Thanks for the reply.

The ball cock on the feed and expansion tank might have jammed or the cold feed pipe could be blocked.

I will check this out. Thanks. It will be tomorrow now. goodnight. Thanks again.

If you bleed the highest radiator in the house, does water squirt out forcefully?

If yes, you have enough water

If no, you haven't, so then you look in the f&e tank as that is the first and easiest next check. It could be full or empty.

Just checked my water and and everything is fine there. Just tried starting the heating up again, and checked the pump. There is no vibration and the pump gets red hot. The pipes in and out either side are cold, but the pump is hot. Do I need a new pump?

Just hit it with a hammer!

You need to check for voltage on the pump first.

There is clearly voltage on the pump James because its getting hot!

The pump is jammed Simmo.

Look at the FAQ for how to unseized a pump!

No wonder the pump in the video is jammed!

Its been fitted at the wrong angle!

Thought that Andy would have noticed!

Shaft should be horizontal !
