Jandy CL460 460 sq ft Cartridge Pool Filter with 100 PSI Max Pressure and Easy-Clean Design MECH-01 Error Fix: High Filter Pressure — Dirty Cartridge

The pressure gauge reads 8-10 PSI above the clean baseline pressure, indicating the cartridge element is dirty and restricting water flow — normal starting (clean) pressure for the CL460 is typically 10-15 PSI; clean the cartridge when pressure reaches 20-25 PSI above clean baseline; turn off the pump, open the air relief valve on top of the filter, remove the band clamp, lift off the lid, and extract the cartridge; hose off each pleat from top to bottom with a garden hose nozzle; for heavy deposits (oils, lotions, calcium), soak the cartridge overnight in a TSP (trisodium phosphate) solution or commercial cartridge cleaner; if pressure remains high after thorough cleaning, the cartridge is at end of life and needs replacement (Jandy R0554600)
