Can anyone suggest what the problem is please.
I have a Vaillant turbomax pro 28e GB 282
Recently when the shower is on the hot water goes hot and then luke warm and again hot. Getting really annoyed with this and can't really afford to get new boiler.
Has anyone got suggestions as to what the fault could be.
