Leaking boiler - can I fix it?

Well, I finally got a plumber round as I was too much of a scaredy cat to remove the flow sensor adaptor myself. The first bloke came round and looked at it, said "it looks like there's a crack in the whole assembly", and subsequently quoted me £350 to repair it. That didn't fill me with much confidence, so I was telling a good mate of mine about it and he said, "hang on, my cousin's a plumber!"

So, his cousin has been round, we had a chat about it and I left him to it.

Turns out that it was the flow sensor adaptor, it has sort of partly disintegrated. So its top marks to @bransty1! He's going to see if he can get one tomorrow and come back and fit it (the plumber that is, not bransty1)

So, as usual, thank you all for guiding me through things - I really appreciate it and the good new is that it looks like its going to be a hell of a lot less than £350.

I'll keep you up-to-date

Thanks,
Nick.

She's good, but she's not that good

DA, thanks for your unwavering support through all of this; its much appreciated. Thanks to everybody that has contributed to the thread. He charged me £60, which, of course, was mates rates, so I gave him £100, which was a good deal cheaper than the other bloke!

Hello all,

So, the leak reappeared about two weeks later, so I am guessing that another of those components that are housed in that sleeve have disintegrated. The heating has also packed up, I reckon its the pump or the diverter valve. My mate's cousin came back around and had a look while we were out at work. He says that the heating problem might be the pump, but that he's not that familiar with Worcester Bosch boilers and that it could be more than one part failing.

He suggested that I book a WB engineer in, since they will fix almost anything, including multiple problems, for around £250, which they will, so that's what I have done. They should be here on Wednesday.

The thermostat has also packed up (the LCD segments have nearly all disappeared), its a Honeywell CM907, and I am looking to replace it with a DT90E.

Since my knowledge of anything electrical is actually far worse that my knowledge of boilers, I am back here, begging you for more help Will you help me again, is this an easy job to do, or could I end up in a twitching, electrified heap on the living room floor?

Ha ha, no, honestly, if I send pics of wiring, can you good people show me the way?

Ta,
Nick.

 

Hello DA,

You are to the rescue again - many thanks.

That looks easy enough then, I should be able to manage that. Yes, it's fine that it isn't programmable, we'll just turn it on and off when we need it, we rarely ever programmed the other one anyway.

So I assume that the back box has already been done, since the installation manual for the CM907 recommends one. I'll use that for the new one.

I'll make sure I power everything off, I know where the switch for that is.

Thanks again my friend and I'll keep you updated - WB engineer coming tomorrow and it's not a day too soon!!

Cheers,
Nick.
