Maximize your dishwasher’s performance: how to fix a faulty frigidaire upper spray arm

A malfunctioning upper spray arm in your Frigidaire dishwasher can significantly hinder its cleaning performance. If you’re facing this issue, fret not! This comprehensive guide will walk you through the steps to fix the upper spray arm, restoring your dishwasher’s efficiency.

Causes of a Non-Spinning Upper Spray Arm

• Clogged Nozzles: Food particles and mineral deposits can accumulate in the spray arm’s nozzles, blocking water flow.
• Faulty Water Valve: A malfunctioning water valve may not provide sufficient water pressure to power the spray arm.
• Damaged Spray Arm: The spray arm itself can become damaged or misaligned, preventing it from spinning properly.
• Inoperative Circulation Pump: The circulation pump circulates water throughout the dishwasher, including to the spray arms. A faulty pump can hinder water flow.

Troubleshooting and Repair

1. Check for Clogs

• Remove the upper spray arm by grasping it firmly and pulling it straight down.
• Use a toothpick or a thin wire to gently remove any visible clogs from the nozzles.
• Rinse the spray arm thoroughly under running water.

2. Inspect the Water Valve

• Locate the water valve, usually connected to the bottom of the dishwasher.
• Turn off the water supply to the dishwasher.
• Disconnect the water line from the valve and check for water flow. If water flows freely, the valve is likely functional.

3. Examine the Spray Arm

• Inspect the spray arm for any cracks, dents, or misalignment.
• Ensure that the spray arm is properly seated on the upper rack support.
• If the spray arm appears damaged, consider replacing it.

4. Test the Circulation Pump

• Remove the lower access panel of the dishwasher.
• Locate the circulation pump, usually at the bottom of the dishwasher.
• Manually rotate the pump’s impeller. If it rotates freely, the pump is likely functional.

5. Clean the Filter

• The dishwasher filter can become clogged with food particles, which can restrict water flow.
• Remove the filter and clean it thoroughly with hot water.

6. Replace the Spray Arm

• If all other troubleshooting steps fail, you may need to replace the spray arm.
• Purchase a compatible replacement spray arm for your Frigidaire dishwasher model.
• Install the new spray arm by aligning it with the upper rack support and pushing it into place.

7. Reassemble and Test

• Reinstall the lower access panel and reconnect the water line to the water valve.
• Turn on the water supply and start a test cycle.
• Observe if the upper spray arm spins freely and distributes water evenly throughout the dishwasher.
