Ecovacs User Interface / Keypad Failure

Robot lawnmower display or control panel buttons do not respond reliably.

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

Moisture under keypad, Worn membrane switches, Loose display board connector, Cracked control PCB

Safety first: Turn OFF the mower and disconnect the battery before opening the control panel.

Dry and clean: If the panel appears fogged or damp, allow it to dry indoors. Do not use heat guns.
Inspect ribbon cable: Ensure the cable between the display/keypad board and mainboard is fully seated.
Test individual buttons: After reassembly, test each button for consistent response.

If certain keys remain unresponsive or the display flickers, replace the display/keypad board assembly.
