How to Clean the Water Intake in a Frigidaire Dishwasher

A properly functioning water intake valve on a Frigidaire dishwasher creates a supply of water adequate for the optimum washing of dishes. If the valve becomes clogged, it prevents a full flow of water, and dishes do not receive the full pressure necessary for thorough washing and rinsing. When dishes come out of a Frigidaire dishwasher not quite clean, inspect and clean the water intake.

  Unplug the dishwasher. Turn off the water supply valve. Place a tub or bucket under the point where the water supply tube connects to the inlet fitting.

  Soak the parts in a solution of equal parts vinegar and warm water for several minutes. Wash the parts in hot, soapy water and rinse. Make sure the screen is fully cleaned.

  Loosen any buildup in the black rubber tubing by submerging the end in the vinegar solution for several minutes and scrubbing the inside with a long, thin pipe cleaner.
- 8
  Clean the end of the water supply tube connections and the the inlet fitting, using a pipe cleaner.
