Front-Load Washer Odor & Mildew Prevention

One of the most common washing machine complaints we hear—especially with front-load washers—is a mildew or musty smell. Fortunately, this issue is often preventable with proper care.

To help prevent front-load washer odors:

• Use only HE (High-Efficiency) detergent.

• Use the correct amount of detergent. Most loads require only about 2 tablespoons of HE detergent.

• Run a hot wash cycle periodically to help remove detergent residue and buildup.

• Leave the washer door open between uses to allow the interior to dry.

• Clean the weep holes at the 6 o'clock position of the door seal using tweezers or needle-nose pliers.

• Wipe down the door seal (boot) regularly to remove moisture, detergent residue, and debris.

These simple steps can help prevent mildew growth and keep your washing machine smelling fresh.

Washer Drain Filter Maintenance

If your clothes are still very wet at the end of a cycle or your washer is not draining properly, a clogged drain filter may be the cause.

If your washing machine has a homeowner-accessible drain filter, we recommend cleaning it every 3–4 months. Always consult your owner's manual for model-specific instructions.

If your washer still won't drain after cleaning the filter, professional washer repair may be needed to diagnose drain pump, control board, or drainage system issues.

How to Clean a Washer Drain Filter

1. Remove the filter access panel, usually located near the bottom of the machine.

2. Drain the pump using the built-in drain hose into a shallow pan or basin.

3. Unscrew and remove the filter.

4. Remove lint, coins, hairpins, and other debris.

5. Soak the filter in hot water to help break down residue and buildup.

6. Gently scrub with a soft brush and rinse thoroughly.

7. Remove any debris from the filter housing.

8. Reinstall the filter securely before operating the washer.

Regular drain filter maintenance can improve drainage performance and help prevent costly washer repairs.

Common Washer Leak Causes

If your washer is leaking, there are several simple checks you can perform before scheduling service.

Check Your Water Supply Hoses

• Inspect hoses for drips, cracks, bulges, or signs of wear.

• Check hose connections at both the wall and the washing machine.

Washing machine hoses should be inspected regularly and replaced when signs of wear appear. Learn more about inspecting and maintaining your washer drain and fill hoses.

Inspect the Door Seal

• Clean the front door glass and rubber door seal regularly.

• Even small debris can prevent the seal from closing properly and cause leaks.

Check the Drain System

• Observe a drain cycle to look for drain hose leaks.

• Check for standpipe overflows or drainage restrictions.

Many washer leaks can be identified early through routine inspections and maintenance.
