BOILER PROBLEM----PLEASE HELP!!!!

[sergey]

my Wickes Combi 102 boiler central heating is fine. My hot water although, is coming out intermittently, it is hot for roughly 10-15 seconds and then cold for 10 seconds and then hot again. The main burner is constantly switching on and off whilst the hot water tap is open.

blocked plate heat exchanger or min gas pressure too high.could also be faulty thermister

You really need someone who knows whats what to look at this.
Wickes boilers are usually re badged Halsteads
To start a list if what could be wrong with it May I suggest a HW or CH thermistor or perhaps a blocked plate heat exchanger

Plate HE blocked on system side.

Remove and clean with DS40.
