Frigidaire Dishwasher Making Noise

Quick answer

A noisy Frigidaire dishwasher is often due to loose parts, debris, or worn components. Turn off power and water, check for loose items, clean the filter, and inspect the drain pump. If the noise persists, replace the pump or call a professional.

Confirm the symptom

• Unusual loud noise during operation
• Noise only when dishwasher is running
• Noise is consistent or intermittent

Tools and prep

• Screwdriver set
• Plastic putty knife
• Replacement parts (if needed)
• Work gloves
• Turn off power at circuit breaker
• Turn off water supply

Step-by-step troubleshooting

1. Check for Loose Items
   Do: Open the dishwasher door and look for loose racks, utensils, or dishes.
   Observe: Any loose items vibrating or clanking.
   Means: Loose items can cause noise during cycles.
   Next: Secure or remove loose items and restart the dishwasher.
2. Inspect the Filter
   Do: Locate and remove the filter at the bottom of the dishwasher.
   Observe: Debris or buildup in the filter.
   Means: A clogged filter can cause the pump to work harder and make noise.
   Next: Clean the filter thoroughly and reinstall it.
3. Check the Drain Pump
   Do: Access the drain pump (usually at the bottom of the dishwasher).
   Observe: Debris in the pump or damaged impeller.
   Means: A clogged or damaged drain pump can cause loud noises.
   Next: Clean the pump or replace it if damaged.
4. Inspect the Motor
   Do: Listen for unusual motor sounds while the dishwasher runs.
   Observe: Loud humming or grinding noise.
   Means: A failing motor may need to be replaced.
   Next: If the motor is faulty, contact a professional technician.
5. Check the Spray Arms
   Do: Remove and inspect the spray arms for clogs or damage.
   Observe: Clogged holes or bent spray arms.
   Means: Clogged spray arms can cause uneven water flow and noise.
   Next: Clean the spray arms or replace them if damaged.
6. Test with an Empty Load
   Do: Run an empty cycle to see if the noise persists.
   Observe: Noise continues without dishes or racks.
   Means: Internal components may be the source of the noise.
   Next: If noise continues, further inspection or professional help may be needed.

Common causes

Parts matching

If you need to replace parts, match these common issues with the right components:
