Baxi 80e DHW problems

[Jake.]

Hello everyone, merry Christmas

We have a Baxi 80e combi boiler but have had no hot water for the last few days. The central heating is working fine and occasionally the DHW will work if the CH is on at the same time - but most times the DHW just doesn't get heated at all, regardless of whether the CH is on or off.

Sometimes the DHW will kick in if I mess about with the Reset/CH&DHW/OFF/DHW knob on the front of the boiler while a hot tap is running, but even if I get it working like this it fails to work again the next time I turn on a hot tap.

I read in another thread on here that there's also a reset switch inside the boiler but I can't seem to locate it. (I could take a photo if it helps)

All the LEDs on the front panel behave normally and no errors are reported. The LED for DHW illuminates correctly on the rare occasion the boiler sees fit to heat some water for us.


Any help diagnosing the fault would be much appreciated.


Thanks

Is that definitely the problem? You terse answer doesn't fill me with confidence, to be honest.

I guess this is rather a quiet forum, judging by the lack of responses to this and a lot of the other threads. :shrug:


Anyway, thanks for the reply fitz1, I suppose it was better than nothing.

Quiet forum, you joking? There were 60+ topics, probably a couple of hundred replies yesterday alone.

If you do a search on "diaphragm" you'll find a zillion posts about exactly the same problem.

Any help would be much appreciated...... Well fitz tells you what it requires and with symptons you describe he is spot on which is why no one else answers. An you come back with smart a#s answer.. Well go with your instinct and ignore the cheap repair . Hope you get ripped off
