Worcester Bosch HE 30/35

Hello,

The hot water isn't hot enough, in the past we had to put loads of cold in the bath but now on it's hottest setting the bath isnt hot enough. I have tried the basics, pressed the little chimney sweep button, let more water in to keep the dial on Green. Any ideas please?

Thanks.

You sure you've named your boiler correctly? Not heard of a HE 30/35.

It means your divertor valve is working ok

OH right, so thats a good thing? I thought these newer boilers could do both at once?

 

[vicvapour]

No sorry mate.

Ah right, thanks for that, are there any more tests I can do? What does the chimney sweep button do?
