please help

hi there, i was wondering if someone could help me with my problem.

my worcester bosch 28si boiler sometimes cuts out with the red flash once a second.

I have noticed this seems to happen when the hot water tap is run normally when the central heating is on.

I have also noticed that the water gets really hot no matter what position the selector dial is on.

does anyone know what part is causing this and where i can get it from.

i do not necessarilly want to fix the boiler myself i just want an idea of what i can check myself or what is wrong as i hate getting robbed by the bad plumbers in this world ( sorry to all you good ones )
thankyou

If you dont want to be robbed by a "bad plumber" then i would suggest you contact an heating engineer.

Anyway, whats the difference between a bad plumber and a good plumber. Do they advertise differently
