BOILER RUNS CONSTANTLY c/H & WATER WITHOUT TIME CLOCK ON OR OFF ---REPLACED MAINFLOW THERMO CENSER BUT NO CHANGE ---BOILER RUNNING AS IF OVERRIDEN ALL CONTROL'S HELP!!! :(
 
Which Eurocombi? Is the control panel white or grey?

Its probably the diverter valve sticking jamming the microswitch on or the switch is faulty.

Presuming its the white control panel (model A23(7)MFFI) have a look at the switch in the plastic box behind the gas valve. The pin should only extend with the tap on.
 
COULD BE LEAK IN HOT WATER PIPE CAUSING THE DIVERTOR TO STAY OPEN BECAUSE IT REGISTERS AS HOTWATER DEMAND. IS YOU CAPS LOCK STICKING?
 
Perhaps both the diverter valve AND the caps lock are sticking?
