Boiler display is blank but pump or fan occasionally runs

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Faulty display PCB, Loose ribbon cable between display and main PCB, Low voltage supply fault on PCB, Water ingress into control panel

Safety first: Isolate power before removing the front panel or control fascia.

Power cycle: Turn the boiler off and on at the fused spur to see if the display returns.
Inspect connections: Check the ribbon cable or plug between the display and main PCB for secure seating and signs of corrosion.
Engineer tasks: Test low-voltage supplies on the PCB, replace the display module if faulty, and address any water ingress issues.
