The Whirlpool WP8535371 Dishwasher Timer is a critical component that controls the entire wash cycle in your Whirlpool, Estate, Inglis, or Roper dishwasher. This electrical component acts as your dishwasher's brain, controlling the timing and sequence of operations such as water loading, spraying, emptying, and heating. 2During a wash cycle, the timer sends signals to various dishwasher components, instructing them when to turn on and off based on the selected cycle. A broken timer can result in issues such as the dishwasher not starting, running for an excessively long time, or failing to complete a cycle completely. Replace a broken timer with the genuine WP8535371 to restore dishwasher performance and effectiveness.
