I fitted a new diaphragm to my baxi combi last year, it literally took 20 mins including getting the tools out! gas fitter quoted me over £100 to do it and i paid £12 for the part!
During the last cold snap the boiler packed in the day before we were going away to a wedding for 2 days (they always go at the most inconvenient and coldest time!) turned out to be the PCB, luckily i now have a good and reasonable gas fitter handy,
Solar panels are tempting!

She complained that she can only get decent hot water when the Central Heating is on. If the heating is not on, she just gets tepid water out of the hot taps, from her Combi.

FYI... contacted Baxi service arm and they came out next day... They reported that, if a fault was present, the boiler should display an error code (which it never had).

The engineer stripped & checked the boiler but found no faulty parts. He alluded to the potentially inadequate installation by the plumber who did the install (no evidence of flushing / cleaning the system prior, no detail / test results on the receipt / certificate of conformance etc) and in the end changed some small part (my mother in law didn't ask what ...) and re-tested it. After further tweaking the ma in law declared herself happy (make a note in your diaries ladies & gents... ) and hot water was available at last!  ...

Be true to yourself. That way happiness lies...
