Thanks for the suggestions..... It has had several parts replaced over the years but has generally been quite good I would say although it's on it's third main control board now.

The boiler is a Baxi Combi 133 HE Plus which is quite old now. The problem is that when the thermostat calls for heat, the pump comes on and the boiler fires up as expected. The flow pipe gets really hot but after about 2 minutes the boiler stops firing and the pump continues to run. After a a...

It's not like I shorted the switch out or anything, I just tapped it and I assume it then found it's proper position. The switch will now be replaced very soon anyway! I guess if the switch can stick closed it could stick open too but do you think a tap with a screwdriver handle would make that...

The flow switch seems to be the problem. I turned on the hot tap and then tapped the flow switch with the head of a screwdriver and the boiler fired up and burst into life! It must have been stuck or possibly had some debris in it. I guess it might need replacing if that was the problem! It's...

Yes, plenty of pressure. It failed on Saturday and the system was drained down on Friday but it worked fine Friday night and Saturday morning.

I hadn't posted an update here before because the guy didn't come back to fit the part and the boiler has been working fine since my last post. Now it seems to have failed completely - it comes up dry fire at the point in the cycle where the burner should fire up. I think I can hear the main...

Weirdly it seems OK this morning. I left it doing the 1 minute on 3 minutes off last night expecting to wake to a freezing house but the heating was on when I woke up and it's been running fine all day.

That sounds likely - that way the hot water would be fine but the CH wouldn't work. If the control board switched it to CH but it stayed on HW then there would be flow through the CH pipework but the heat exchanger would be heating the HW instead of the CH. Would that cause the main pump to stop...

Yes the pump is inside the boiler but you can still tell when it's running or not. The valve that opens is whichever one of the two way valves controls the zone that is calling for heat - or sometimes both when they both are below set temperature. System has 2 zones, one for main rads and other...

Boiler is a Baxi combi 133HE+ and has been having a few problems. The current problem is that when the thermostat calls for heat, the valve on that circuit opens and after a few minutes the main CH pump starts to run. The pump runs for almost exactly a minute without the boiler firing up and...

Our house has a small tiled porch roof with gallows brackets outside the front door. I decided to box this in with a timber frame and cladding. The idea was to put a door in the middle with windows to either side. The whole thing is only just under 2m wide and about 75cm deep. I started off...

Parts fitted now and all warm again! The engineer said I should get the parts myself after listing the items I needed as he said it would be cheaper and quicker to get them online than for him to order them. He showed me the prices he would have charged and I saved about £150 by getting brand...

Well the heating engineer came round today and diagnosed that the burner assembly had completely disintegrated and the ignition and flame detection electrodes were shot. Just awaiting the parts to come and he will fix it. Quite an expensive job! Fingers crossed the parts don't take too long to...

Thanks for the reply Terry! That sounds reasonable in this case. The bangs sound just like explosions in the combustion chamber so I will make some calls. I hope the weather isn't too cold for the next couple of days! These combi boilers leave you a bit exposed when they break down don't they!

I went to do the washing up and turned the hot tap on and heard a loud ban from the boiler! I turned the tap off straight away but the boiler kept on making the banging noises so I turned it off at the mains. Waited 5 mins and turned it back on, turned the tap on and it starts banging again and...
