MECH-QD-CLOGGED
Polaris · Polaris 280 Pressure-Side Pool Cleaner
The quick disconnect (QD) fitting or its internal screen at the pool wall is clogged with debris, restricting water flow to the cleaner: (1) Remove the hose from the wall fitting and inspect the screen inside the QD. Clean out leaves, sand, and debris. (2) The UWF (universal wall fitting) has a removable restrictor disc inside — check that it is correct for your cleaner model. Some models require the disc removed for maximum flow. (3) If the pool has fine debris (sand, DE powder, algae), the screen clogs frequently. Consider running the pool filter longer before running the cleaner. (4) Check the UWF eyeball fitting inside the pool — make sure it is clear and water flows freely.
