Intermittant Hot Water. Help!!!!

[tenchking]

Hi, have a problem with my Worcester 24CDI boiler,
CH seems fine but if i take a shower, run a bath or turn on any hot tap the boiler fires up no problem, continues running for a few minutes, then after about 4-5mins cuts out for about 10-15 seconds then fires up again for about 10-15secs and so on and so on cutting in and out.

Have run a tap and watched the boiler, no indicator lights flash to indicate a fault just the pilot light indicator which comes on and goes off as the boiler cuts in and out.

Any ideas would be very very welcome as getting really cheesed off with having cold showers every eve.

Cheers.

Yeah. Whats the problem?

Run hot water ,boiler goes through sequence up until ignition ,and then goes to flamefailure flashes twice per second.I have replaced aps have also disconnected white lead to condense trap.Is a sensor an option or does this sound familiar to any one. the boiler does not even try to ignite.
