Jandy CL460 460 sq ft Cartridge Pool Filter with 100 PSI Max Pressure and Easy-Clean Design MECH-02 Error Fix: Cracked Filter Tank or Lid

Error code MECH-02 on the Jandy CL460 460 sq ft Cartridge Pool Filter with 100 PSI Max Pressure and Easy-Clean Design means: Cracked Filter Tank or Lid. The filter tank body or lid has developed a visible crack, causing water to leak under system pressure — cracks typically develop from UV degradation of the polymer tank over many years of sun exposure, from over-tightening the band clamp beyond specifications, from freeze damage if the filter was not winterized in cold climates, or from physical impact; small surface cracks may be temporarily repaired with marine-grade epoxy or fiberglass repair compounds, but replacement of the cracked component (tank body or lid) is recommended for structural integrity and safety; the tank is under pressure during operation and a catastrophic failure can cause injury
