I have a Worcester 37cdi boiler that is 2 years old and just today when you turn on the hot water taps within 20 seconds, the water's hot and the temperature goes to 100c and then it goes back to 0, where the water then becomes cold. Also at this point the boiler makes irregular noises. Any questions just ask

Sounds like a blocked secondary plate heat exchanger.
Was the system power flushed when the boiler was fitted?
Or was it a cheap cowboy install?
If only two years old it should still be under the installer's/manufacturer's warrantees.

I would second the blocked plate.
Am I correct in guessing that you mean it goes hot and then cold, rather than litterally 100 to 0?
Does the cycle repeat when you keep the hot water on, and if so, what interval?

sound like the pump to me!
it may be sticking or slow (its an 8 speed pump)
do you mean it overheats and goes to 100plus on the visual display. or at the tap! was your system flushed??
