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
Clean cycle every month.

According to the soil level within the cycles and the frequency of the cycles, you have to inspect
and clean the filter regularly.
The pump should be inspected if the machine does not empty or no spin;
The machine makes an unusual noise during draining due to objects such as safety pins, coins
etc. blocking the pump.
Removing foreign objects from Lint Trap / Coin Trap:
The Coin Trap (Lint Trap) can collect small objects from the wash cycle. Clean out the coin trap
regularly to ensure normal operation of washing machine. Please allow the unit to cool down sufficiently
before opening the coin trap knob as hot water may be present. The Coin trap door is located on the
front, bottom right hand side of the machine.
IMPORTANT: A small amount of water may be present in the
coin trap and will be released when knob is opened. Please
have a towel and/or small drain pan to catch any water.
WARNING: Hot water may be present if machine has not
been allowed to cool down sufficiently. Please allow unit to
cool down prior to removing coin trap knob.
5
Freeze Prevention and Help:
If your washing machine is located in the room where it can get frozen easily, please drain the
remaining water inside drain pipe and inlet pipe thoroughly. Remove the remaining water in the inlet
pipe and drain pump.
If unit experiences a freeze when water has not been preventatively drained, please follow the below
instructions.
1. Disconnect the power supply for the washing machine.
2. Wash the supply valve / supply tap with warm water to loosen inlet pipe.
3. Remove supply lines / inlet pipes and immerse in warm water to thaw.
