Symptom / Description

FAULT

Hotpoint ActiveCare & GentlePower Heat Pump Dryer: Lower condenser filter blockage warning F23; differential pressure switch or temperature delta detects restricted air path.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On Hotpoint tumble dryers: Compressed sponge filter saturated with damp lint in bottom plinth compartment, or warped filter frame allowing air bypass.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1Open plinth door, pull out foam filter element, wash thoroughly under running water, squeeze dry with towel, and reinstall firmly into cassette housing. Press and hold Power button for 5 seconds, remove lint from filter screen, and restore main power.

1. Pre-Intervention Electrical Safety Protocols
  • !Electrical Safety Protocol: Cut 230V mains power before accessing the upper chassis or pressure switch terminals.
  • !Drain appliance tub completely before disconnecting pressure switch sensing hoses.
  • !Never blow high-pressure compressed air into electronic analog pressure sensors: internal diaphragms will rupture!
3. Preliminary Mechanical & Visual Checks
  • Disconnect the silicone pressure tube from the lower air trap and inspect for soap sludge, lint, or water blockage.
  • Inspect the flexible rubber hose along its entire length for pinholes, cracks, or loose clamp fit.
  • Thoroughly flush the lower compression chamber (air dome) with hot water to dissolve detergent buildup.
Perform these diagnostic steps before triggering AI Deep Search or replacing boards.Certified Workshop Routine
