Symptom / Description

FAULT

Brandt BPI / BTI MaxiZone Induction Cooktop: Auto-Stop safety timeout triggered AS; all induction cooking zones shut down automatically after liquid spillover or prolonged cooking.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On Brandt cooktops utilizing MaxiZone 28cm induction generator, 10-point safety pack, and responsive touch slider controls: Boiling liquid overflowed onto capacitive touch keys, metallic utensil left on keys, or unattended cooking timeout reached.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1Remove hot cookware and wipe glass surface completely clean and dry with a dry cloth. Touch the master On/Off key to resume normal cooking. Wipe glass surface completely dry, power down main circuit breaker for 60 seconds, restore power and press Key Lock sensor for 4 seconds.

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.
