Combo 4e OK on gas not electric

[Torchy]

Been away for a few days to try everything out as MH has been locked up since September.
Combi 4e working ok on gas but nothing on electric.
Have took the inspection cover off combi and noticed a red light on right hand side.
Does this indicate a fault and if so how can I fix it. Someone has told me to press it till it turns green. Is this correct.

Have you checked to see if something has tripped?

Mine was the other way around - working on electricity but not on gas. The red light under the inspection cover was lit. I pressed the microswitch and got an amber and then a green. It starting working an gas again.

I have a short video of the fault if this helps.
