Hi there,
I have a Glow Worm Micron 40FF boiler, fitted in 2003 in a new-build property.
The unit is displaying a 'Software Error' LED Fault Coding (LED 1 (Reset) is on, LED 2 (Burner Lit) is slow flashing (2Hz)).
I tried switching the unit off (Control Knob at '0', and Power off at isolation switch) then starting it up again 24 hours later, but the problem persisted.
Does this mean the PCB needs to be replaced?
If the PCB (Part No. 2000227134) needs to be replaced, has it been replaced by an updated part? If so, what is the new PCB part number I need to purchase?
Is it necessary to replace the thermistor if the PCB is replaced? Some of the posts on the forum state that it is necessary.
Thanks in advance,
Stuart
