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.
