Inspect rubber perimeter door seal for tears or gaps.
Test RTD sensor resistance curve at ambient vs heated temps, reprogram offset calibration in logic board.
Debris jammed in chopper blade, failed check valve flap, or burned wash/drain motor windings.
Twist out bottom micro-mesh filter and wash under hot faucet.
Inspect air-gap assembly, replace one-way rubber flapper valves, and test electronic drain cycles.

Never disassemble internal chassis panels, bypass internal thermal fuses, or tamper with pressurized gas and refrigeration lines.
Filter cleanings, breaker resets, external hose checks, leveling adjustment.
Internal wiring access, motor replacements, sensor calibrations, gas valve checks.
Facing an Urgent Breakdown or Gas Hazard?
