Products that might damage your washing machine
• Concentrated bleaches and diaper sanitizer will cause damage to the paintwork and components of your washer.
• Hydrocarbon solvents i.e. petrol, paint thinners and lacquer thinners, etc. can dissolve plastic and blister paint
(Be careful when washing garments stained with these solvents as they are flammable DO NOT put them in
washer or dryer without presoaking and rinsing them first.)
• Some pretreatment sprays or liquids can damage your washer’s control panel.
• Use of dyes in your washer may cause staining of the plastic components. The dye will not damage the machine
but we suggest you thoroughly clean your washer afterwards. We do not recommend the use of dye strippers in
your washer.

When there is a possibility of freezing ambient temperatures.
• Close the water taps and remove the Water Supply Hose.

• Connect the water supply hose to the water tap and confirm that the washing machine performs the
supply and drainage of water.
Wash Inner-tub
Leave the lid open after washing to allow moisture to evaporate. If you want to clean
the inner-tub use a clean soft cloth dampened with liquid Detergent, then rinse. (Do
not use harsh or gritty cleaners.)
Inlet Hoses
It is recommended to replace the inlet hoses to the tap every 5 years.
