Amana Washer Smells Musty After Hot Wash: Troubleshooting... | appliancefaults.com

Technical Background:

Amana washers utilize a Main Control Unit (MCU) to manage wash cycles, water levels, and motor functions. Voltage pathways control fill valves, drain pumps, and heating elements. Mold and mildew thrive in damp environments, particularly when residual detergent and fabric softener create a breeding ground.

Symptoms:

US homeowners notice a persistent musty or mildew smell emanating from their Amana washing machine after running a hot water wash cycle. The smell may transfer to clothes washed in the machine.

Possible Causes:

Buildup of detergent and fabric softener residue.
Mold or mildew growth in the drum, dispensers, or hoses.
Standing water left in the washer after cycles.
Clogged drain pump filter.
Insufficient hot water temperature reaching the washer.
Venting issues if the washer is located in a poorly ventilated space.

Solution:

1

Unplug the washer from the outlet.
2

Remove the detergent dispenser drawer. Clean the drawer and the housing with a brush and hot, soapy water.
3

Inspect the rubber door gasket for mold. Wipe with a 10% bleach solution, wearing gloves and eye protection.
4

Locate and remove the drain pump filter (usually behind a small access panel at the bottom front). Clean the filter and housing.
5

Check the drain hose for clogs. Remove the hose from the back of the washer and flush with water.
6

Run a self-clean cycle with a washing machine cleaner (e.g., Affresh) or 1 cup of bleach on the hottest setting.
7

After the cycle, leave the washer door slightly ajar to promote air circulation.

Safety Warning:

Disconnect power to the washer at the breaker panel before performing any maintenance. Washing machines operate on 120V AC, which can cause serious injury or death.

Prevention:

Always use the correct amount of detergent and avoid overusing fabric softener. Regularly clean the detergent dispenser and door gasket. Run a self-clean cycle monthly. Leave the washer door slightly open between washes to allow the drum to dry completely.

Expert Tip:

Some Amana washers have a service mode that allows you to run specific tests and diagnostic functions. Refer to the service manual for your specific model to access and utilize these features. A common sequence might involve pressing and holding a specific button combination for several seconds.

Frequently Asked Questions

•How often should I run a cleaning cycle on my Amana washer?

It is recommended to run a cleaning cycle on your Amana washer at least once a month, or more frequently if you notice a musty odor or excessive detergent buildup.

•What type of washing machine cleaner is best for my Amana washer?

Use a washing machine cleaner specifically designed for high-efficiency (HE) washers. These cleaners are formulated to remove detergent residue and prevent mold growth without damaging the washer's components. Affresh and Tide Washing Machine Cleaner are popular options.

•My hot water heater is far from the washer. How can I ensure the hot water is hot enough?

Consider insulating the hot water pipes leading to the washer to minimize heat loss. You can also run the hot water tap in a nearby sink or tub before starting a hot wash cycle to ensure that hot water reaches the washer quickly. If the problem persists, consult a plumber about potentially upgrading your hot water heater or installing a point-of-use water heater near the washer.
