Should You Clean the Washing Machine Pump Filter?

The answer

Clean the pump filter if your washer has a user-serviceable filter and the manufacturer tells you to maintain it. Whirlpool says the filter on some front-load models should be cleaned occasionally or as needed, but the owner’s manual controls for the exact machine.

Why

Whirlpool explains that the pump filter can collect lint and debris and that accumulation can hinder draining. It also states that the filter can be cleaned on some models, which is the important limitation. Before opening an access panel, confirm that the model actually has a user-serviceable filter and follow its draining precautions because residual water can come out when the filter is opened.

When it is usually OK

• The owner’s manual identifies a drain or pump filter as user-serviceable.
• The manufacturer gives an interval or “as needed” cleaning instruction.
• The washer shows symptoms such as slow draining and the manual lists the filter as a check.
• You can disconnect power and safely collect residual water as the instructions require.

When you should not

• The washer manual does not show a user-accessible pump filter.
• The pump filter is not identified as a user-cleanable part for the model.
• Residual water has not been drained according to the manufacturer procedure.
• The washer still will not drain after the documented filter check and needs further troubleshooting or service.

Risks and exceptions

• Residual water can spill when the filter is opened unless the manufacturer draining procedure is followed.
• A filter that is not reinstalled in the documented position can leave the maintenance procedure incomplete.
• Cleaning a pump filter that is not user-serviceable on your model goes beyond the manufacturer’s maintenance guidance.
• Cleaning the filter will not correct a separate pump or drain-system fault.

Best practice

Check the exact owner’s manual for a drain-pump-filter procedure. If the filter is user-serviceable, disconnect power, follow the residual-water instructions, clean the filter and reinstall it exactly as directed.

Alternatives

• Use the manufacturer’s washer-maintenance cycle when the issue is odor rather than drainage
• Check the drain hose when the owner’s manual lists it as a troubleshooting step
• Use manufacturer service support if the filter is inaccessible or the washer still will not drain
• Continue with the model-specific drainage troubleshooting sequence rather than repeatedly cleaning the filter
