Odor

Problem

Possible Cause & Solution

Odor

Some odor is caused by the rubber attached to the washing machine.

• This odor is normal for new rubber and will disappear after the machine has been run a

few times.

If the rubber door gasket and door seal area are not cleaned regularly, odors can occur

from mold or foreign substances.

• Be sure to clean the gasket and door seal regularly and check under the door seal for small

items when unloading the washer.

Odors can occur if foreign substances are left in the drainage pump filter.

• Be sure to clean the drainage pump filter regularly.

Odors can occur if the drainage hose is not properly installed, causing siphoning (water

flowing back inside the washing machine).

• When installing the drainage hose, be sure that it doesn’t become kinked or blocked.

Using the dry function, odors can occur from lint and other laundry matter sticking to

the heater. (Dryer model only)

• This is not a malfunction.

A particular odor can occur from drying wet clothes with hot air. (Dryer model only)

• The odor will disappear after a short while.
