Ideal FF360 boiler problem

[Tawnyowl]

I was woken up one morning by a loud banging noise from the CH which was soon found to be due to the boiler over heating and creating steam. At the boiler I turned the temperature control down ( it was on 5) and the burner turned off. Worried it might come back on again I then decided to turn the whole CH off.

Hours later when everything had cooled down I turned it back on but now it was completely dead. The pump didn't run and the boiler didn't fire up. After a good deal of investigation I decided that the control board (known as PCB 25E) was the culprit and obtained a new one.

After fitting it (not so easy is it) I turned it back on but it is still completely dead. I've checked that mains is reaching the PCB and that the fuse hasn't blown. There's what appears to be a led light on the board but it's not coming on.

So does anybody know what has really happened here and how to fix it?

Easy fix call a heating engineer in and stop wasting your money on parts that don’t need replacing.

well now that you have wasted money on a PCB that you didnt need go back and buy a pump and replace the faulty one that you have then re-set the OH stat

Or something else!

Trying hard to be positive, but what lead you to the conclusion that a PCB would be a good investment?

ye a gas safe heating engineer just give up

If in doubt go for the PCB
