Polaris Polaris Alpha iQ+ Robotic Pool Cleaner with iAquaLink MECH-WONT-MOVE Error Fix: Cleaner Powers On But Does Not Move

Error code MECH-WONT-MOVE on the Polaris Polaris Alpha iQ+ Robotic Pool Cleaner with iAquaLink means: Cleaner Powers On But Does Not Move. The power supply shows green (normal operation) but the robotic cleaner does not move in the pool. The cleaner is receiving power but the drive system is not engaging: (1) Track/tread jammed — pull the cleaner out and check for debris wrapped around the tracks, wheels, or drive gears. Hair, string, and leaves commonly jam the tracks. (2) Drive motor failure — if the motor is burned out, the cleaner will receive power but cannot move. This requires professional repair or motor replacement. (3) Drive belt broken (on belt-driven models) — the internal belt connecting the motor to the tracks may have snapped. Open the cleaner to inspect. (4) Gearbox failure — the internal gear train can strip or seize. Listen for motor humming without movement (indicates jammed gears). (5) Check the floating cable for internal breaks — the cable may carry power for lights/pump but have a broken conductor for the drive motor.
