Customer Questions and Answers for Timer (Dishwasher Cycle Control) by Whirlpool

This mechanical timer sequences the dishwasher through its wash, drain, and dry steps. Replacing a failing timer restores proper cycle advancement so the dishwasher starts, progresses, and finishes cycles reliably. What it does:

• Times and sequences power to the wash motor, drain pump, fill valve, and heater for each stage of the cycle
• Advances the cycle automatically and moves the dial/indicator through programmed steps
• Coordinates wash, rinse, and dry durations for consistent results
• Typical failure symptoms: cycle won't advance or stops mid-cycle; runs too long; must be advanced manually; timer knob won't turn

• 1 mechanical timer assembly

• Disconnect power at the breaker before servicing; do not rely on the control panel to turn the unit off
• Access the timer from the control console/inner door; remove screws to reach the component
• Photograph/label wire positions and transfer leads to the new timer one at a time
• Reuse existing mounting hardware and knob; ensure the shaft orientation matches before reassembly
