Polaris Polaris P965iQ Robotic Pool Cleaner with iAquaLink MECH-SWIVEL Error Fix: Cable Swivel Stuck or Not Rotating

Error code MECH-SWIVEL on the Polaris Polaris P965iQ Robotic Pool Cleaner with iAquaLink means: Cable Swivel Stuck or Not Rotating. The cable swivel — the rotating connector between the floating cable and the cleaner — is stuck, seized, or spinning freely (stripped): (1) Stuck/seized — the swivel allows the cable to rotate as the cleaner turns, preventing cable winding. Over time, mineral deposits and corrosion can seize the swivel. Try soaking it in a calcium/lime/rust remover and working it back and forth. (2) Stripped/spins freely — if the swivel rotates without resistance, its internal mechanism is stripped and it is not functioning. The cable will tangle quickly. Replace the swivel. (3) Swivel location — the swivel is usually at the cleaner end of the cable, sometimes at both ends. (4) Replacement — swivel assemblies are an inexpensive wear part. Replace them every 1-2 seasons as preventive maintenance.
