Replaces discontinued GE part number WD21X10476.🇺🇸 Matching U.S. Part Number: WD21X33641 Part WD21X33641 Replaces WD21X10476 GE / Hotpoint Dishwashers Electromechanical Cycle Timer WD21X33641 is a genuine GE dishwasher cycle timer used in select GE and Hotpoint dishwashers. It replaces discontinued GE part number WD21X10476. The timer mounts behind the dishwasher control panel and sequences electrical power through the selected cycle, controlling when the dishwasher fills, washes, drains and completes other timed portions of the cycle. Is This the Right Part? Part NumberWD21X33641 Replaces (OEM)WD21X10476 ManufacturerGE Appliances Appliance TypeDishwasher BrandsGE, Hotpoint ConditionSee variant selected Confirm the complete dishwasher model and revision before ordering. The timer knob and timer cam are separate components — they are not included unless the selected variant specifically states otherwise. WD21X10476-8PK and WD21X33641-8PK are eight-pack service references, not single-unit OEM predecessors. Common Symptoms Dishwasher not starting Cycle not advancing — dishwasher remains in one stage Dishwasher stopping mid-cycle Dishwasher running continuously without advancing No drain, fill or heat during a specific timer position Timer knob not moving through the cycle Intermittent or erratic cycle operation Check Before Replacing Check the door-interlock switch — a failed door switch prevents the timer from receiving power and can mimic a timer fault Inspect the timer knob and cam for damage — a broken knob or cam can prevent the timer shaft from advancing without the timer itself being defective Check for drain-solenoid, pump, water-inlet valve or heating-circuit faults — a component failure at a specific timer position can appear as a timer problem Inspect wiring and connectors at the timer for looseness, corrosion or damage before replacing the assembly Confirm the electrical supply voltage is correct before replacing the timer Pro Tip: Before replacing the timer, test the door-interlock switch for continuity — it is one of the most common causes of a dishwasher that will not start and is far less expensive to replace than the timer. If the switch tests good and the timer still does not advance, confirm that the timer motor receives voltage during operation before condemning the timer assembly. Part Details Part TypeDishwasher Cycle Timer Primary FunctionSequences electrical power through the fill, wash, drain and drying portions of the selected cycle Timer TypeElectromechanical Related ComponentsWD09X10024 (black knob), WD09X10025 (white knob), WD16X10012 (timer cam) — sold separately Installation Notes Disconnect electrical power and shut off the water supply before opening the control panel or handling timer wiring. Photograph the timer wiring harness and terminal positions before disconnecting any wires. Compare the new timer with the original — confirm the terminal layout, shaft configuration and mounting points match. Transfer the timer knob and cam from the old timer if they are compatible, or order the correct components separately. Reconnect all wiring harnesses and restore power. Test the dishwasher through a complete cycle and confirm the timer advances correctly through each stage. Use a qualified technician when diagnosis or installation is outside your experience.
