I have a Combi Boiler. When I run the hot water tap water is running out of the overflow pipe in the loft but I can't see where the overflow pipe comes from. Can anyone help please?

Are you sure you have a combi?
With a combi the hot water goes direct to the taps.
There is no need for an overflow.
Are you writing that the water coming from the overflow is hot?
Has the system been working correctly, before this problem?

Does it only happen on bathroom taps ? - kitchen taps fine ?
