potterton boiler problem!?

Have a look in your airing cupboard... The Suprima will normally be fitted with either 2 motorised valves, or 1 single (3 way) valve... It is this device that turns the appliance on and off by a series of micro-switches (Usually the orange [output] and grey [perminant live] wiring)... Check that these switches and valves are operating correctly first.

Also check your pump... As you may find your hot water is coming on, but not circulating, thus the boiler will turn off pretty quickly via the boiler thermostat.
