Washer-dryer combo has a strong musty or moldy odor inside the drum.

Safety first: Use only cleaning products approved for washers; avoid mixing chemicals.

• Clean gasket: Wipe the door gasket thoroughly with a cloth and a solution of hot water and mild detergent or a washer-safe mildew cleaner. Pay attention to folds where water collects.
• Run cleaning cycle: Use the washer's tub clean cycle with a commercial washer cleaner or 1 cup of liquid chlorine bleach (if allowed by GE for your model).
• Improve drying: Leave the door and detergent drawer slightly open between uses to allow air circulation.
• Check drain: Clean the drain pump filter to ensure water fully drains after cycles.
