sounds like a pump problem you need a plumber

Hi

It is either the pump (which I doubt, as it runs when hot water is demanded) or the flow switch. Thw flow switch indicates the water is moving and enables the burner to fire. These devices do fail sometimes or some have adjustment on them and can be set during part of the commissioning process.
Look in the manual and see if you can locate the flow sensing device and then if it is adjustable.
