Quick answer
A washer making noise when draining often indicates a clogged drain pump or issues with the pump itself. Turn off the washer, check for blockages, and clean or replace the pump if necessary.
Confirm the symptom
- Noise occurs only during the drain cycle
- The noise is loud and possibly grinding or gurgling
- Water drains slowly or not at all
- You hear the pump trying to work but struggling
Tools and prep
- Screwdriver (flathead and Phillips)
- Flashlight
- Bucket or towels
- Work gloves
- Plumber's putty or sealant (if resealing connections)
- Turn off the washer's power and water supply before starting
Step-by-step troubleshooting
- Check for ObstructionsDo: Locate and remove the drain pump filter or access panel. Inspect for debris, coins, or small objects.Observe: Find and remove any blockages.Means: The noise may be due to a clogged pump.Next: If the pump is clear, move to the next step.
- Inspect the Drain PumpDo: Visually check the pump for damage or wear. Test by spinning the impeller manually.Observe: The impeller may be stuck or damaged.Means: A faulty pump needs replacement.Next: Replace the drain pump if damaged.
- Check the Drain HoseDo: Inspect the drain hose for kinks, clogs, or improper installation.Observe: Find any kinks or blockages in the hose.Means: A blocked hose restricts water flow and causes noise.Next: Straighten or replace the hose if necessary.
- Test the WasherDo: Restart the washer and run a drain cycle to see if the noise persists.Observe: The noise should be gone if the issue was resolved.Means: The problem may be fixed.Next: If the noise remains, consider professional help.
- Inspect the Motor CouplingDo: Check the motor coupling for wear or breakage. This is located near the motor and pump.Observe: The coupling may be cracked or slipping.Means: A damaged coupling can cause unusual noises during operation.Next: Replace the motor coupling if damaged.
- Check the Water Level SwitchDo: Ensure the water level switch is functioning correctly and not stuck.Observe: The switch may be faulty or misaligned.Means: A faulty switch can cause incorrect water levels and drainage issues.Next: Replace the water level switch if necessary.
Common causes
| Cause | Likelihood | Difficulty | Part often needed |
|---|---|---|---|
| Clogged Drain Pump Debris or objects block water flow, causing the pump to work harder and make noise. | Common | Easy | Drain Pump Filter or Pump |
| Faulty Drain Pump A worn or broken pump cannot move water efficiently, leading to noise and poor drainage. | Common | Medium | Drain Pump |
| Kinked or Clogged Drain Hose A kink or blockage restricts water flow, causing the pump to strain and make noise. | Sometimes | Easy | Drain Hose |
| Worn Motor Coupling A damaged coupling between the motor and pump can cause misalignment and noise. | Sometimes | Medium | Motor Coupling |
| Faulty Water Level Switch An incorrect water level reading can lead to improper drainage and noise. | Rare | Medium | Water Level Switch |
| Loose or Worn Parts Loose components can vibrate or rattle during the drain cycle. | Sometimes | Easy–Medium | Various (e.g., screws, brackets) |

FAQ
Can I use a plunger to unclog the drain pump?
A plunger may help with minor clogs, but avoid forcing it to prevent damage. For persistent clogs, remove the filter or pump for thorough cleaning.
How often should I clean the drain pump filter?
Clean the drain pump filter every 3–6 months, depending on usage and water hardness.
What if the noise happens only during the spin cycle?
Noise during the spin cycle may indicate a different issue, such as a problem with the motor or bearings. Check the motor coupling and ensure the washer is level.
Is it safe to replace the drain pump myself?
Yes, if you follow safety steps and have the right tools. Turn off power and water before starting. If unsure, consult a professional.
Why is my washer making a grinding noise when draining?
A grinding noise often indicates a clogged or faulty drain pump. Check for obstructions and inspect the pump for damage.
