Apologies for the mixup - its only when I looked at the photo I realised it was a Instant - I've done most of these posts at work, so had to rely on the manual I downloaded ages ago! So if the pressure going up is another fault - what would be doing that? Thanks for your help Ian.

Just checked and its a Baxi Combi Instant 105E So does it make sense about repressurising the pressure release valve before swapping the diaphragm?

Just tried to get a part and spoke to a very helpful guy at the local shop. He's advised that where the pressure fluctuates between 1 and 2bar that the pressure release valve needs re-pressurising first, and it can be done with a bike pump to about 7psi, but have to use the drain tap first...

Thanks for the reply. When you say very easy - does it need to be done by a gas engineer or a simple diy job? Thanks

Strange update......after re-pressurising last night we had hot water - didn't run a bath or anything but seemed to be running hot enough for a while. Woke up this morning and we didn't have any hot water again, then managed to get enough to fill half a basin before it went cold again, and...

Thank you so much for your help - we have hot water. Thanks for saving me a call out fee for a 1 minute job!! Just confused why the heating still worked - is that not as dependant on pressure as the hot water? Thanks again.

Have looked into the process to re-pressure and it says about adjusting both ends of the silver pipe to increase the pressure. Trying to get my head around exactly how this increases the pressure - could someone point me in the right direction? Thanks a lot.

Thanks for the reply fella - daft question and I'm just curious why this wouldn't affect the heating then? Increasing the pressure is the same as re-pressurising then - and fairly straightforward?

Good morning all, wonder if anyone can help with a problem with my Baxi 105e boiler. Had no hot water this morning, but the heating works fine - even with heating on, get no hot water. Held left dial in reset position for 10-20 secs but to no avail. No warning lights are on - I am...
