Immergas Display Backlight / LCD Failure

Display is blank but the unit appears to run (hot water is produced).

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

Failed display module, Loose display connector, Low supply voltage to display, Control board display driver fault

Safety: Isolate power before accessing electronics.

Check supply voltage: Have a technician verify low‑voltage supply from the main PCB to the display.
Inspect connectors: Reseat the display connector and check for corrosion.
Replace display module: If wiring and supply are correct, replace the Immergas display/user interface module.

Note: Operating without a display makes diagnostics difficult; repair promptly.
