Can anyone tell me what it wrong when the LED on my Potterton Suprima boiler is slowly Flashing ORANGE.
I know that it flashes Orange quickly if the Temp Switch is turned off but this is flahing Orange slowing and not starting up when the central heating thermostat is turned up and calling for heat??
There is nothing in the manual about a SLOW Flashing Orange LED.....
Any ideas anyone?
