Troubleshooting
Before calling a service supplier, please check 
the following posible causes/soluting.
  If the problem is not fixed after checking the above possible causes, or if you still think something is
  wrong, disconnect the body plug from the unit. Wait at least 10 seconds and then re-connect the plug.
  The semi-transparent inner part inside the lid may become yellowish. This does not affect operation of the unit.
 The ratting noise in the lid is made by small ball-shaped components which prevent water from 
  flooding out if the unit topples over.
  If the room temperature is very high, the outside of the main unit may reach about 131ºF (55ºC).
The unit does 
not turn on.
  It is broken if the electric  
  components are taken in
  water. Contact the stores  
  where you purchased  
 for 
repair.
  You poured in water directly from a tap.
  You put the unit on the sink.
  You turned the unit upside down with 
  its bottom wet.
  You washed the unit water.

Causes/Solutions
White or glittering
flakes floating in 
the hot water.
  The cause of this is “scale”. (See P.20) 
  It is not flakes of fluororesin.
 * Water with a large content of minerals  
    in it such as mineral water or ionised  
    water, is more likely to cause a scale  
    or white layer in the hot water.
  When “scale” adhered, boiling sounds  
 become 
louder.
Boiling sounds 
become louder.
  Odors of chlorine remain depending on  
  the amount of chlorine in tap water.
Hot water has 
odors of chlorine.
  When the unit is new, resin used in the manufacturing process may  
  give off a mild odor.
  If the unit is placed on surfaces such as a vinyl sheet, the odor may be  
  carried over into the water.
Hot water has an 
unpleasant odor.
  Water has been added above maximum  
 water 
level.
Hot water comes 
out by itself.
  Lower the water level.
  The mesh filter may be clogged with  
  “scale”. (See P.20)
Hot water does not 
flow out smoothly.
  Clean the filter with a brush.
  If the “scale” cannot be removed, 
  replace the filter. (See P.23)
  Overheating protection has been activated  
 (See 
P.15)
The indicator lights 
flash alternaterly.
  Add water and press the  
 “Reboil” 
key.
  The indicator lights may flash alternately  
  by adding boiling water or due to the way  
  the water is supplied.
  Press the “Reboil” key.
  When the inner container is cleaned with citric 
  acid, citric acid may have built up on the bottom.
  Disconnect the plug, and stir  
  the citric acid well to disperse.
  The automatic lock has been engaged.
Hot water does 
not dispense.
  Press the “Lock/Unlock” key.
