I had a new Potterton Supprema 80 HE boiler fitted 18 months ago. Since then we have had a number of ignition lockout problems. Eventually after getting the installer to reset the sensor gap which partially rectified the problem, an Potterton engineer came under the warranty, fitted a new sensor and blamed the previous sensor gap. the problem went away for several months.
Now that it has come out of warranty, we are getting intermittent ignition lockout problems again, a couple of times a week.
On start up, there is a spark and the flame establishes from right to left. It then extinguishes. After several attempts it will either establish itself or occasionally lockout. When it locks out if you reset the temp control knob it will retry and normally fire up. I had the plumber back who installed it and they have changed the sensor yet again, with no joy, and changed the pcb. It has improved marginally but still fails a couple of times a week. he is at a loss for further suggestion and suggests going to Potterton direct. They have just quoted minimm price of £239.
Any suggestions for other things to try before reverting to this option. There seems no real pattern, at one time it looked like occured on cold mornings, but has also happend on warm everning
I see from web sites that the pcb is often quoted as problem for older models, but when I chose a Potterton I had been advised that the new model was better. Is it likely 2 pcb are that poor quality
