Make: Potterton Promax SL
For the past 3 days, I've noticed that my boiler does not start the ignition sequence when calling for HW/CH anymore, there is no whirring sound. I have to press the Reset button for it to begin the sequence and fire up.
I took the casing off just to have a look at the light indicators. Left light flashes red. No light on middle light and On is solid green

Is there any troubleshooting advice before calling an engineer?
