Hotpoint Washer Smells Like Mold or Mildew:... | appliancefaults.com

Technical Background:

Modern washing machines utilize a Main Control Unit (MCU) to manage wash cycles, water levels, and motor operation. The MCU receives input from various sensors (e.g., water level sensor, door switch) and controls outputs to components like the water inlet valve, drain pump, and motor. The drain pump is particularly relevant, as its proper function ensures complete water removal, preventing moisture buildup and subsequent mold growth. Voltage to the drain pump is typically 120V AC.

Symptoms:

The homeowner notices a moldy or mildew smell emanating from inside the washing machine drum. The odor may be more noticeable after the washer has been idle for a period of time.

Possible Causes:

Trapped moisture after wash cycles
Low-temperature washes insufficient to kill bacteria
Excessive detergent usage creating residue
Poor ventilation around the washer
Detergent dispenser buildup
Clogged drain pump filter

Solution:

1

Run an empty washer cycle with chlorine bleach. Add 1 cup of liquid chlorine bleach to the dispenser and select the hottest water setting. Let the cycle complete.
2

Clean the detergent dispenser. Remove the dispenser drawer and soak it in warm, soapy water. Scrub away any visible mold or detergent buildup. Rinse thoroughly and reinstall.
3

Inspect and clean the rubber door seal (gasket). Carefully peel back the rubber seal and check for mold or mildew growth. Clean with a mixture of water and bleach (10:1 ratio), using a soft cloth. Wear gloves.
4

Clean the washer drum with a washing machine cleaner. Follow the instructions on the cleaner label, typically involving running a cleaning cycle.
5

Check and clean the drain pump filter. Locate the drain pump access panel (usually at the bottom front of the washer). Place a shallow pan underneath to catch any water. Open the panel and unscrew the filter cap. Remove the filter and clean out any debris or lint. Reinstall the filter and cap securely.
6

Ensure proper ventilation. Leave the washer door slightly ajar after each use to allow the drum to dry completely. Ensure adequate airflow around the washer.
7

Use the correct amount of HE detergent. Using too much detergent can lead to residue buildup, promoting mold growth. Refer to the detergent instructions for the proper amount.

Safety Warning:

Disconnect power to the appliance at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental re-energization. Some components may retain high voltage even after the appliance is unplugged.

Prevention:

Regularly run a cleaning cycle with a washing machine cleaner or chlorine bleach. Wipe down the rubber door seal after each use. Leave the washer door slightly ajar to promote air circulation. Use HE detergent in the correct amount.

Expert Tip:

Many Hotpoint washers have a service mode that allows you to run diagnostic tests and access error codes. To enter service mode, typically you have to press a combination of buttons on the control panel in a specific sequence. Consult the technical sheet for the exact procedure for your model.
