My inherently crap Potterton Suprima 30 is on the blink again!
This time, its not sparking.
The timer comes on, the pumps start up and the little green light on the boiler starts blinking, but there's no sparking and the gas valve isn't opening (I'm assuming the gas wont turn on until it starts sparking). Then a I get a SOLID green light and the red starts flashing.
I'm unfamiliar with this light configuration, lockout is a flashing red with no green, but this is a solid green with a flashing red.
Couple of occasions, whilst the boiler has been left on in this state, it will suddenly strike up after a time on its own (it starts sparking and the gas comes on and lights).
So I'm assuming its something to do with the ignition circuit? (and yes before you ask, the thermostats are asking for heat).
I had a new PCB and Gas Valve a couple of years back, so I'm hoping its neither of those. I did put a new lead on the ignition a couple of years back, so I don't think its that.
Anyone give me a heads up on what I should check first?
TIA
