Robot vacuum shows E16 and stops when moving; may report a stuck wheel even when wheels appear free.

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

Wheel height sensor misreading, Debris under wheel suspension, Wheel motor sensor failure

Safety first: Turn OFF the robot and flip it over.

Clean around wheels: Compress each drive wheel up and down and remove any debris from the suspension wells.
Check for free movement: Spin each wheel by hand. If one feels rough or catches, clean more thoroughly or consider replacing the wheel module.
Test on flat floor: Place the robot on a flat hard floor and start a cleaning cycle. Avoid thick rugs or thresholds during testing.

If E16 persists on flat surfaces, the wheel lift or stall sensor integrated in the wheel module may be faulty.
