❶
Simply rinse thoroughly with water and wipe the inside liner with a clean
sponge or paper towel.
• To prevent damage to the water heater do not use alkaline cleaning agents
when cleaning, use a soft cloth and a mild detergent.
• Do not use any material such as a cleanser or scrubber for tough stains
or mineral deposit; this is to avoid damage to the non-stick (flouropolymer)
coating surface.
• All water that contains minerals will leave mineral residue on the inside
liner when boiled. If not cleaned for a prolonged period, mineral build up or
stains may become tough or louder noises can be heard while boiling water.
Frequent cleaning is recommended.
• Mineral deposit will eventually block the pipes and/or the steam vent if not
removed. This blockage will cause the motor unit to burn when the "Dispense"
key is pressed persistently.
• Do not scrub and/or do not use a knife to remove the mineral deposit.
• Discoloration caused by a dry boil is not removable.
Caution
❷
For mineral build up, use citric acid cleaner every 2-3 months (refer to p. 17)
■
Uneven colors or discoloration of the inner container and
floating white material in the water
Red spots such as rust, milky white discoloration, black spots, iridescence that appear in the
inner container, and floating white material are caused by a reaction of the minerals (calcium,
magnesium, iron, etc.) contained in the water. This is not discoloration, rust, or peeling of the
fluoropolymer-coated surface of the inner container itself. Although there are no sanitary /
health concerns, frequent cleaning is recommended when the heater starts to show stains.
Wipe off stains with a damp cloth or paper towel.
Wipe off with dry cloth.
Remove the mesh filter from inner container. Wash with soft brush e.g.: tooth brush.
• Do not soak the unit in water and do not pour water on the unit, this is to avoid shorting or electric shock.
• Never wash the entire unit, this is to avoid water getting inside the unit to cause malfunction.
• Do not use harmful materials such as detergent, thinner, cleanser, bleach, metal scrubber, nylon scrubber,
and chemically-treated wiping cloths.
• Do not put in the dishwasher or dish dryer, this is to avoid deformation.
