1. Pre-Intervention Electrical Safety Protocols
  • !Electrical Safety Protocol: Isolate 230V mains power before accessing the lower pump housing.
  • !Prepare a shallow basin and absorption towels: expect 3 to 10 liters of stagnant trapped water upon filter opening.
  • !Beware of sharp foreign objects (broken glass, needles, screws) trapped inside the impeller cavity.
3. Preliminary Mechanical & Visual Checks
  • Unscrew coin trap filter and clear all foreign debris (coins, hairpins, bra underwires).
  • Rotate pump impeller manually: synchronous magnetic rotors should snap cleanly in 90° intervals without jamming.
  • Check drain hose for kinks, blockages, or unpunched sink spigots; verify drain height is between 65cm and 100cm.
