Boiler high pitched noise in cold weather?

[Lewis Davies]

Hi, can anyone help me resolve this issue with my ideal logic combi Esp1 35.

It is making a very loud high pitched noise whenever the outside temperature is cold, when either CH or HW is being used.

For example, first thing in the morning on a cold day, run hot tap or turn up CH stat and the boiler will make a high pitch noise before settling down. The noise is very loud and lasts about 10 seconds. On a warm day I won't get the noise at all?

Condensate drain is clear and trap cleaned.

Would really appreciate any thoughts. Cheers

When was it last serviced ?

Stangely we have the same boiler doing exactly the same, we called out an approved ideal engineer, they serviced the boiler and gave it a clean bill of health, but it was still squealing with the engineer present. £65.00

They ordered a new jet and venturia (all it really need was a light clean) it squealed after the engineer had left, they charged us £225 for the 2 visits, the first time they turned up without the parts.

They returned under there 12 months warranty and changed the gas valve, then sent us bill for £162.00 ?

It still squealing?

This is a common one on the Logics , sorry no advice given but a good GS engineer could sort it .
