The appliance has an unpleasant odour.
Are you using the appliance for the first time?
The odour is caused by the rubber material inside the appliance. The odour normal when the appliance is new and disappears after you run several cycles.
Do you smell an odour during use?
Do not exceed the manufacturer's recommended amount of detergent when washing clothes. Excess detergent can build up on clothing and cause odours.
Leaving clothes in the washer or dryer after the cycle ends can lead to odours. Unload clothing promptly when the cycle ends.
For ventless models, leave the dryer door open after drying, or use the magnetic door stop (on some models) to keep the door slightly ajar.
If the odour is coming from the washer, follow the instructions in the product manual to clean the washer tub/drum.
Keep both lint filters clean. Clogged or dirty lint filters can cause odours. After cleaning the lint filter, allow it to dry completely before using it.
Periodically run the Drum Care and Condenser Care cycles following the instructions in the MAINTENANCE section.
