Davey pool pump controller shows dE and the keypad does not respond correctly.

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

Damaged keypad membrane, Moisture behind display, Loose ribbon cable between keypad and main board, Failed display PCB

Safety first: Turn off power before removing the controller fascia or display panel.

Step-by-step checks:

1. Inspect for moisture: Look for condensation or water droplets behind the display window. If present, allow the unit to dry thoroughly.
2. Check keypad cable: If accessible, reseat the ribbon cable connecting the keypad to the main PCB.
3. Test buttons: After drying and reseating, restore power and test each button for response.

If dE remains and buttons are unresponsive, the keypad/display assembly will likely need replacement.
