Polaris Polaris Alpha iQ+ Robotic Pool Cleaner with iAquaLink LED-RED-SOLID Error Fix: Power Supply Solid Red LED — Motor Stall / Stuck

Error code LED-RED-SOLID on the Polaris Polaris Alpha iQ+ Robotic Pool Cleaner with iAquaLink means: Power Supply Solid Red LED — Motor Stall / Stuck. The power supply unit shows a solid red LED indicator light. This means the robotic cleaner's drive motor has stalled — typically the cleaner is stuck on an obstruction such as a drain cover, ladder, step, or corner. The power supply shuts down motor power to prevent damage. To resolve: (1) Pull the cleaner out of the pool and check for debris wrapped around the tracks, wheels, or brushes. (2) Remove any large debris from the filter canister that may be causing excessive drag. (3) Check the floating cable for tangles — a tangled cable limits the cleaner's range and causes it to get stuck. (4) Check the pool for obstacles the cleaner cannot navigate (raised main drains, protruding fittings). (5) Power cycle the PSU — unplug, wait 30 seconds, replug. If the red LED returns immediately, there may be a motor or cable fault requiring service.
