Thanks for getting back!
It's a Mini C28 NOO2921204 / 47-348-19 / GC158324
There is one diagnostic light which flashes green...a standby flash of 4 secs....and when it's on...a 2 sec flash. There's an ignition lock out lamp...which never comes on.
The boiler is about 5 years old and due...
Hi all. We have a Mini Ideal C28 that takes 3 to 9 times to ignite the gas and get going. Water or CH.
It clicks on...there's a whirring....and then.....CLUNK!
And then it tries again.
We've had a new divertor valve, diaphragm and motor fitted recently.
But none have fixed this...
