Ideal evoHE

Hi guys

My boiler is driving me insane. It's an Ideal evo HE C22/30. When the heating goes off (on timer) it doesn't actually shut off. The only way to shut it off is by the isolator switch. I can only get hot water when the heating is on. This started a couple of weeks back when I noticed a change in the boiler sound on firing up. On checking the pressure gauge, I found that it was on zero (no leaks). I re-pressurised it and it's been ok.

I'm guessing that the problem is the diverter valve but wanted to ask for opinions before buying the part.

Cheers!

Thanks superman. I will try with the help of my glamorous assistant as the boiler is a crawl away in the loft.

Cheers

Hi Superman.

I was unable to test as you suggested because as soon as I switch the boiler on at the isolator switch, the heating comes on regardless of what the control box says: on, off, auto, all day etc. Didn't have a chance to draw on DHW with a cold ch flow pipe.
