Boiler whining noise

[Lydsmillsy]

Hi all

I have an Ideal Icos HE24 boiler. When I switch on the central heating, it starts making a loud whining noise and will eventually stop after around 5 mins. Sometimes it’ll start whining again and then stop intermittently.
I’ve noticed that if I turn on the hot water, it doesn’t whine.
A gas engineer has been over and checked all the main parts and he can’t seem to find what’s wrong.
Any idea what could be causing this?

You need someone who knows your boiler, it is most likely to be a combustion issue

The only other thing I would possibly check is if it has an autobypass fitted near the boiler, they can whistle/whine sometimes.

I’ve switched on the heating this morning and it’s not once whined. So strange

Has it been freezing up your way?

I recorded it and played it to the engineer who came over.
No I didn’t pay him. He contacted Ideal technical support whilst he was here as he wasn’t sure. He’s ordering some parts based on what Ideal have advised it could be.

Yes in the night it has.

Oh dear and who pays for the parts and labour when it doesn't cure the problem? Hope it sorts it.
