CLEANING AND MAINTENANCE

Exterior Cabinet:

Never use solvent based, abrasive cleaners, harsh chemicals, or steel wool to clean your unit as they
can damage the finish. The cabinet and door may be cleaned with a mild, non-abrasive detergent and
lukewarm water solution. Use a soft sponge and rinse with clean water. Wipe with a soft clean towel to
prevent water spotting.

During daily use it is recommended to wipe up any spills with dry soft cloth.

Internal Drum:

Never use solvent based, abrasive cleaners, harsh chemicals, or steel wool to clean the internal drum.
During daily use, use a soft cloth to wipe around the door, opening, and rubber seal to remove any
excess moisture and to maintain a water tight seal.

To clean the interior of the unit, all clothes must be removed from the drum. For liquid chlorine, add
directly to the fabric softener section. For powder tub cleaner, add directly to the main detergent
section. Use only cleaners labeled as safe for washing machines.

 Select the cycle “Self Clean” and press “Start” to initiate the Self Clean cycle.

NOTE: It is recommended that you run the Self Clean cycle regularly to help remove detergent buildup
and other residue. Depending on how frequently the machine is used, you may need to run the Self
