Ideal Indipendent C24 Condenser Boiler

[EEZABLADE32]

Hi,
the above is out of guarantee ( 4 years old ) and has a water heating problem ( CH fine ). When running a bath the blue burner light comes on and the water gets hot ( but not too hot ). After about 10 minutes with a quarter full bath the light goes out and water goes cold. Any ideas would be appreciated and wonder what a repair would cost, roughly.

Thx

Tony

For a remote diagnosis I would say its the DHW flow switch.This sensor detects the water flow and if its faulty may tell the PCB that no water is present ...this then shuts the burner down.The part could cost around £25 and up to an hours labour to fit.
