I have a fault on a combi that is tripping the overheat on the top of boiler on occasions when heating's on and hot water is run, generally when taking a shower.
Checked the overheat stat and seems ok tho haven't replaced it. Does not trip if heating called for OR hot water demand called for individually.
The manual isnt much help.
Any ideas anyone? Corgi reg no 1705
