It was by a registered engineer it is a new part and he replaced it in the same place as the old one. He has now said it MUST be something to do with wires but cant get the part for a week with no hot water and two little ones im hoping theres another solution!
We have a Ideal boiler it is displaying a LE fault replaced the PCB and STILL showing same fault! When you rest it is flashes D like its working and goes back to a fault.
Can anyone help?
