The General Electric WD21X33641 Dishwasher Timer is a replacement part for GE dishwashers that is really essential. It controls the sequence of operations on the dishwasher (e.g., filling, washing, rinsing and draining) and adjusts the wash cycle by defining the amount of water to be dispensed in each operation. This timer guarantees cycle timing for maximum cleaning performance. https://www.hnkparts.com/wd21x33641-general-electric-timer
