Washer has a persistent musty or moldy odor, especially in front-load models.

Safety first: Unplug the washer before deep cleaning internal areas.

Step-by-step:

• Run cleaning cycle: Use a washer cleaner tablet or a cup of white vinegar on a hot cleaning cycle per Whirlpool instructions.
• Clean door boot: Wipe the rubber gasket folds with a mild bleach solution to remove mold. Dry thoroughly.
• Clean dispenser: Remove and scrub the detergent drawer and housing.
• Leave door open: After each use, leave the door and dispenser drawer slightly open to allow drying.
• Check drain: Clean the drain pump filter to remove trapped debris that can cause odors.

When to call a technician: If odors persist despite thorough cleaning, there may be hidden buildup in internal hoses or the outer tub that requires disassembly.
