We had an issue previously that the PRV kept blowing, so dumping all the pressure and shutting the boiler down, so was being topped up every few days Turned out that the expansion vessel wasn't doing its job, which is helpfully behind the boiler so either you fit a new one elsewhere or remove...

Its already been dealt with if you had read that "I considered it a fair price" after I DID spend some considerable time reading up on various sites and forums, including here. Trying to decide on what boiler to use is a nightmare. Like buying a new car. Some rave about some makes, then you find...

Yes, its an independant suggested by the local plumbing/boiler parts suppliers after I was looking at a new boiler after the current one broke down again just before Christmas and after spending some time looking him up found he was highly recommended by customer comments on various places...

Sorry, it was a bit vague on what I was supposed to be asking By personal thoughts, I mean personal thoughts on what would be considered 'fair price' for the work involved

Just some personal thoughts on pricing for the following we are having done next week after having our boiler replaced. I think its a fair price when hunting on the 'net and considering whats involved, plus the cost of the Baxi Duo Tec 24HE I finally chose and was suggested as an alternative to...

After spending considerable time hunting around, it appears yet another common fault is the water pressure switch failing, giving the impression of low water pressure fault even though there isn't low water pressure I'll look at that in the morning as that's a 5 minute job which I can easily...

I bet they still are around, we have the misfortune of having one that has the exact same fault with 40/80 flashing but water pressure is fine along with a couple of PCB's failing over the past 3 years and 'usual' things that go wrong with them like diverter valves scaling up and failing to work...

Is there a pressure switch that may be faulty, so it thinks there is no water pressure when the pressure is fine. Its at 1bar, just above the red with the boiler switched off Turn the boiler on, the fan starts, you get one click from the air pressure switch, then 40/80 flashing. Thats as far...

No, positive its 40/80 flashing Thats what I can't get, the water was low. Topped it up, but still goes to 40/80 flashing after boiler trying to start The fan is starting, you hear a click which I assume is the air pressure switch then it goes to flashing 40/80 everytime Read...

I'm assuming the switch is at fault, and no there is helpfully no wiring diagram but I do have a fault/flow chart Water pressure is fine, but still getting the ever helpful flashing 40/80. All lights work as it cycles through them as it starts the boiler start-up test so I know an LED isn't...

I may be a DIYer, but if I can rebuild a motorbike engine and motorbikes, plus work on car engines replacing cam belts and such like, and know how to use a multimeter for electrical fault finding properly I'm not your 'average' DIY lunatic who thinks a big adjustable and hammer are all you need...

Got these error lights about 15 minutes ago as I heard boiler go off, pressure a bit low in middle of red so topped it up using cold filling loop Boiler goes through start sequence, you can hear fan come on, but then goes into 40 80 flashing lights again Boiler appears to sound like its...

Thats makes sense, I knew it was a difference in water pressure that caused the diaphram to move the valve to block the central heating supply but couldn't work out why there wasn't enough pressure for the diaphram to move that valve enough to activate the DHW microswitch and divert the water...

Changing the water control valve solved the problems, but still annoying to find a simple spring and cheap thin looking piece of plastic piston can cause so much aggrevation. What a great design ... not

Looking at other diagrams it appears to be a by-pass valve, but the spring/plunger was jammed so allow partial closing/opening of the changeover valve with some but not full water pressure getting through. Yes I knew they were meant to be there but not doing much good rattling around and the...
