Solution
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” has 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 may give off a 
mild odor. This will disappear with use. 
 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.
