    Hi,

    When running the shower the boiler starts up ok warms the water then cuts out. The hot water light goes off. After about 5 seconds it comes back on & heats the water again but cuts off again after 10 seconds. This repeats throughout the shower.

    All but the last temperature lights come on. The water only gets luke warm. The heating workings fine.

    I'm thinking either clean the heat exchanger or replace the DHW temperature sensor?

    Thanks

    It will be the hydraulic venturi, easy to change, just make sure you get all the old bits out as it will have broken up
