Troubleshooting
Before calling a service supplier,
please check the following possible causes/solutions.
Possible cause
If...
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.
●
Clean the filter with a brush.
●
I
f the “scale” cannot be removed,
replace the filter. (See P.23)
●
The automatic lock has been engaged.
Hot water does
not dispense.
●
Press the “Lock/Unlock” key.
●
Clean the inner container
with a wet sponge.
(See P.20)
