1Disconnect power immediately. Measure voltage at heater terminals with cycle paused; if 120V AC is present, replace main control board assembly. Press 3 selected keys in sequence 1-2-3, 1-2-3, 1-2-3 with less than 1 second between presses. All display LEDs light; close door to run rapid diagnostic wash.

1. Pre-Intervention Electrical Safety Protocols

!Electrical Safety Protocol: Cut electrical mains power. Never measure resistance on energized heating circuits.
!Ensure tub water or heating cavity is completely drained and cool to the touch before dismantling.
!Verify absolute zero voltage using an approved 2-pole voltage detector before touching element terminals.

3. Preliminary Mechanical & Visual Checks

Inspect heating element tube for calcification buildup, bulging, pinholes, or blistering.
Check wiring spade terminals for heat discoloration, burnt insulation, or loose crimps.
On thermal Klixon switches: check for manual red reset buttons and verify spring-loaded snap action.
