This is the genuine Maytronics retrofit kit (part 9991273) that replaces the cable-to-motor connection assembly on the Dolphin Supreme M5 and a wide range of compatible models. It restores the sealed electrical interface between the floating power cable and the cleaner’s drive unit, ensuring reliable signal and power transfer in a pool environment. The ‘2010’ designation refers to the connector generation, distinguishing it from the earlier 3-pin retrofit (9991279).<\/p>\n
The kit rebuilds the watertight junction where the power cable plugs into the robot body. A corroded, cracked, or leaking connector at this point interrupts motor drive signals and can cause the cleaner to stop mid-cycle or fail to start. Replacing the full assembly \u2014 plug, pins, gasket, and bonnet nut \u2014 restores electrical continuity and the environmental seal in a single repair.<\/p>\n
Confirmed compatible models include the Supreme M3, M4, M5, Wave 65\/90, Wave 60\/80, C3\/C4, M200, M400, M500, Oasis, Nautilus CC Plus, Nautilus CC Supreme, Triton Plus, Sigma, Odyssey, and Aquarius XL. It is also listed for the Dolphin M250, Supreme M4 PRO, M5 PRO, Explorer, Explorer Plus, Pulit E55\/E70\/E80\/E90, Zenit 10\/15\/20\/30, F40\/F50\/F60, SF40, and SF60. Verify your specific serial number against the Maytronics parts diagram before ordering, as the Supreme M5 carries multiple connector references.<\/p>\n
The cleaner powers on at the PSU but the robot does not move or stops immediately \u2014 a symptom that points directly to a broken connection at the cable entry point. Visible corrosion, green oxidation on the pins, or a cracked triangular plug body are clear physical indicators. A connector that no longer seats firmly and allows water ingress will also cause intermittent behaviour during a cleaning cycle.<\/p>\n
Unscrew the bonnet nut to release the old plug assembly from the cable end, slide the new triangular plug onto the cable pins, seat the O-ring gasket against the robot body socket, and tighten the bonnet nut finger-tight plus a quarter turn. No soldering is required \u2014 the kit is a direct swap that takes under ten minutes with no special tools.<\/p>","protected":false},"excerpt":{"rendered":"
