Vokera User Interface / Control Panel Fault

The boiler display is on, but it does not respond to controls or buttons.

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 keypad or encoder, Damaged display PCB, Loose ribbon cable between the UI and main PCB, or a software lockup.

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

Power cycle: Turn off the boiler at the spur for 30 seconds, then turn it back on to see if the controls respond.
Engineer tasks:
- Inspect and reseat the ribbon cable between the user interface and the main PCB.
- Test keypad functions and replace the control panel if unresponsive.
- Update or reset firmware if supported by the model.

Do not spray cleaners directly onto the control panel; moisture can damage the electronics.
