angie they are not bad boilers , old yes but there are worse going around, if you remove that cover , it is only 1 screw and behind the cover you will see 3 more leds what are they showing ?
2 red LEDs lit near the bottom of the circuit board (other than the Lock out' flashing light.
It fired up today of its own accord but stopped again after 35 mins
The left LED means boiler lockout through flame failure, the right LED means faulty thermistor or PCB, was that replacement a brand new one ? or from Ebay ?
I'm getting into a sticky spot now, going into overdraft and can't afford a grand towards a deposit on a new boiler.
Will have to stick to wrapping up and boiling pans for a bit longer.
