Symptom / Description

FAULT

Machine stops mid-cycle, especially during heating.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

The heater relay on the control board is stuck, or a pressure switch fault is causing the heater to run when the drum is empty.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1This is a serious fault. Check the heating element and its wiring. Inspect the pressure switch. The main control board likely needs replacement.

Tolerance & Diagnostic CriteriaMechanical switch contacts must transition cleanly on gentle breath pressure. Coil ~22Ω ±5%.

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.
