Mower displays E17 and stops; the right wheel may not drive 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

Failed Hall sensor in right drive motor, Damaged right motor encoder cable, Loose connector on main PCB, Internal gearbox sensor failure.

Safety first: Turn off the mower and disconnect the battery before servicing the wheels.

Inspect right wheel: Remove any debris and ensure the wheel rotates freely by hand.
Check motor wiring: Follow the right drive motor cable to the main board. Inspect it for damage and reseat the connector.
Functional test: In a flat, open area, power on the mower and observe the right wheel's motion during startup and turns. A lack of smooth motion suggests feedback issues.
Diagnostic swap (advanced): If possible, swap the left and right motor connectors at the board to see if the error changes sides, which can help isolate the fault.

A persistent E17 typically indicates a defective right drive motor/gearbox assembly.
