Help with Potterton performa eco 24e

If the boiler sitched off with the dial on the boiler or with the timer it goes straight to flame failure when switched on.

It does it even with no demand.

If swithced on with demand it's okay and fires up for either water or heating. It will then run okay until demand is released and then goes back to flame failure.

I hope it's something other than the gas valve, as I've just seen the price.

The boiler is just over 2 years old

Get out the multi meter!!

Check your switched live and perm live are going into the correct location on the boiler. Had this once after a spark had done some wiring on a baxi Fire/BBU.

The boiler has been running sweet for 2 years and nothings been changed.

It's just decided to do it the last few days.

It was okay until Wednesday when it did it once. After a quick reset the problem didn't manifest itself again until today.
