Please Help!
hot water keeps cutting out intermitently but heating working. Now not working since repair man has been trying ti fix it!

Had bolier repair out to fix same but he didnt seem to know why. First he said it was PCB board but put a new one it and it got fried!

He then said it was the valve but when he replaced that it worked for 15mins then fried the new PCB board. Now he is saying thst it could be the transformer!!
Feel he is just working his way through each component and doesnt know what to do.
Does anyone have any ideas

What you need is an EXPERIENCED SERVICE ENGINEER, not a Plumber, As Service Engineer will use instruments such as an Electrical Multimeter to work through a logical sequence to come to a Diagnosis, rather than throw bits on untill a cure is stumbled upon.

Hi Sarah.

You emailed this to Worcester Bosch didn't you ;) Worcester don't like to try and give tech advice to homeowners because they never know whether you'll try and attempt a repair yourself.

But for guidance's sake, it's easy enough to test a transformer, he doesn't need to replace it until he's identified whether it's failed or not.

It's a tough call this one, cos there are several components that could cause the fault - we could be looking at a sensor fault, or we could be looking at a heat exchanger problem (but that doesn't account for the blown boards).

How much have you paid your engineer? You may wish to consider calling a Worcester engineer out - they work on a flat fee (£210 unless you live in London) which includes all the parts and a 30 day recall period in case it goes wrong again just after they leave! It comes to a point where if you're paying £150 for a board, and £70 or so for a gas valve, that you have to wonder which way is most economical.

It's almost impossible to pin down the component that's causing this from the details you've given. Sorry.
