Use the suggestions below when clothes are wrinkled, stained, smell musty, or when the washer will not connect to Wi‑Fi.
The washer may be overloaded. - The washer can be fully loaded, but the drum should not be tightly packed. - The door should close easily.
Hot and cold water inlet hoses may be reversed. - A hot water rinse can set wrinkles in garments. - Check the inlet hose connectors.
Bleach or softener may have dispensed too soon. - The dispenser compartment may have been overfilled or closed too quickly, which can cause bleach or softener to dispense immediately. - Measure bleach carefully, and never use more than 1 cup.
Bleach or softener may have been added directly to the drum. - Always use the dispensers so laundry products are released at the correct time in the cycle.
Items may not have been unloaded promptly. - Remove clothes from the washer as soon as possible after the cycle finishes.
Clothes may not have been sorted properly. - Wash dark colors separately from light colors and whites to prevent discoloration. - Never wash heavily soiled items with lightly soiled items.
The right options may not have been selected. - Heavier soils and tougher stains may need extra cleaning power. - Select the Heavy Soil feature to boost the cleaning power of the chosen cycle.
The stains may already have been set. - Items that have already been washed may have stains that are set in. - These stains may be hard to remove and may require hand washing or pre-treating.
Too much detergent, or the wrong detergent, may be used. - Use only HE (High-Efficiency) detergent, and follow the manufacturer’s instructions.
The inside of the drum may not be cleaned properly. - Run the Tub Clean cycle regularly.
Some odors are normal, especially at first. - A smell from the rubber parts of the washer is normal for new rubber and should disappear after the machine has been run a few times.
Other odors can come from parts that need cleaning or checking. - Clean the rubber door gasket and door seal regularly. - Check under the door seal for small items when unloading the washer. - Clean the drainage pump filter regularly. - Make sure the drainage hose is installed properly and is not kinked or blocked, so water does not siphon back into the washer.
If the washer will not connect to Wi‑Fi, check the following:
Why are my clothes wrinkled after washing? The drum may be overloaded, or the hot and cold water inlet hoses may be reversed.
Why did bleach or softener stain my clothes? They may have dispensed too soon, been added directly to the drum, or been used in too much quantity.
What should I do if stains are not coming out? Select the Heavy Soil feature, and consider hand washing or pre-treating if the stains were already set.
Why does my washer smell musty? Too much or incorrect detergent, or a drum that has not been cleaned regularly, can cause odor. Run Tub Clean regularly.
Why won’t the washer connect to Wi‑Fi? Check the password, turn off mobile data, use a 2.4 GHz router, keep the appliance closer to the router, and make sure the network name uses only letters and numbers.
