Customer Questions and Answers for Electronic Control Board (Main Control) by Whirlpool

This electronic control board is the "brain" of the dishwasher, coordinating cycle timing and powering key components. Replacing a failed board can restore normal operation when the unit won't start, stops mid-cycle, or behaves erratically. What it does:

• Manages cycle timing and sequences based on selected options
• Distributes power to the circulation pump, drain pump, water inlet valve, heater, and dispenser
• Monitors inputs from sensors and the door switch to advance/complete cycles
• Faults can present as unresponsive controls, won't start/finish cycles, random resets, or error codes

• 1 electronic control board

• Disconnect power at the breaker before servicing; shut off water supply if accessing the lower compartment
• Use anti-static precautions; handle by the edges and avoid touching connector pins
• Access location varies by model; photograph wiring and transfer one connector at a time
• After installation, run the dishwasher's diagnostic/service cycle to verify operation
