Before calling a service supplier,
please check the following possible causes.
Possible cause
●
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 ionized water, is more likely to
cause a scale or white layer in the hot water.
●
When "scale" adheres, boiling sounds become louder.
●
Odors of chlorine remain depending on the amount of
chlorine in tap water.
●
When the unit is new, resin used in the manufacturing process 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.
●
Water has been added above maximum water level.
●
The mesh filter may be clogged with "scale".
(See P.20)
●
When scale accumulates in the inner container and
remaining hot water is low, hot water does not flow
out smoothly.
●
Immediately after boiling, hot water may not flow out
smoothly.
●
Rubber gaskets may be damaged.
●
It is harder to dispense if the keep-warm temperature or water level is low.
●
Overheating protection has been activated (See P.15)
●
The indicator lights may flash alternately by adding
boiling water or the way the water is supplied.
●
When the inner container is cleaned with citric acid,
citric acid has built up on the bottom.
●
The automatic lock has been engaged.
●
The Push plate lock lever is locked.
●
The lid is opened.
●
You poured in water directly from a tap.
●
You put the unit on the sink.
●

●
You washed the unit in water.
●
This is malfunction of the sensor.
●
Contact the stores where you purchased.
