Thanks guys, I now have a better understanding of how my system works. I am confident that the system is wired up correctly, as it's been working perfectly for 3 years. As far as the plumbing goes, it all seems to be in order, but I'm far from an expert. There haven't been any recent...

Recently I have noticed that when my CH or HW switches off, occasionally the water pump continues going, which gets rather noisy after a while. It happens about once or twice a week. So not everytime the system stops. If I turn up one of the thermostats (CH or HW), wait for the...

Does anyone else have any suggestiones please?

I pretty sure nobody has turned on the immersion heater, as there isn't one! :lol:

Hello, Over the last few weeks I have noticed an odd gurgling, fizzing, shooshing noise comming from what seems to be inside my hot water cylinder tank. I'd describe it as the noise of a small wave receding on a pebble beach. The central heating system is working perfectly, but the noise...

no, but I will now! Thanks

Put on a new motor and it's working a treat. Help yourself to as many hob nobs as you like! I have noticed that since the heating has started working again, the pump is making a strange shwooshing fizzing noise. Like bubbles of air are going through it. I've bled all the rads...

Cracked it! Well hope I have anyway. It was that motor. I took it off of the valve and turned on the central heating. The cog spun for about a minute, the motor got very hot, then it stopped spinning. Problem solved. Very strange for a new motor to do this though, do you...

Ok now I think I'm going slightly mad. Took off the control panel, connected the live upto terminal 4 as you suggested and CH came on for abuot 1 min, then shut itself off. So I followed the live feed all the way through to the motorised valve, to try and work out where the break was...

Thanks, Yes it's profile 80e boiler. And the pipes are hot at the pump, the boiler casing too and the rads close to the pump start to warm up. I can hear the pump circulating the water, and there are no unusual sounds from the boiler. Yes the recent changes were only the syncro...

It's housed inside the box of the motorised valve casing. But that's made of metal! another good conductor of electricity. Just seemed a bit risky to me. But guess it's just as safe as a light switch or any other electrical connection. Thanks for that quick answer Chris. I think...

I'm only guessing that the motor isn't motoring because that would explain the problem. Actually it seems to be motoring fine as far as my limited knowledge goes. It makes a quiet whirring noise when I switch on CH and the lever goes loose. Then when it switches off it makes a louder...

The Boiler is a Potterton 80e. And both valves are 2 port, not 3. I have 'felt' the lever on the CH valve as it is switched on, and it slowly glides to the right hand side (opened position) Which I guess means that it's working. Is it possible for the lever to move over there with the...

Hi Chris, When it all stops..... The boiler just halts as usual. There is no need to press the restart switch underneath it. The boiler stat does click. It stops exactly like the heating reached the temp on the room stat. But this is turned upto max. The Pump stops and the...

Hi all, I have a problem with my central heating system and would be grateful if anyone could tell me what might cause it. Let me describe the problem and my system in as much detail as I can. Basically when I turn on my central heating the motorized valve opens and the pump starts...
