Matters to confirm
Solution
Is there any residue or debris from construction left in
the tank or piping?
Drain and replace the water in the tank.
Please clean the filter.
Circuit Breaker is activated
The hot water is dirty
Phenomenon
Reason
Hot water turns lukewarm
during use
Because cold water is supplied to the tank when hot water is used
continually, the amount of hot water decreases and it turns lukewarm.
Because this product uses the hot water stored in the tank, when the hot
water turns lukewarm with continuous use, it takes time for the water to
reheat.
When used in winter, little
hot water comes out. It now
takes time for the water to
heat
In winter, incoming water temperature decreases. When the length of
piping between the stop valve and the Controller is long it may take more
time for hot water to come out. The lower the water temperature, the
more time it takes for the water to heat.
The output temperature
increases momentarily
This is because during heating, the water remaining in the pipe inside the
device has heated up and been released.
(It is particularly likely that this will occur when the room temperature and
water temperature are high.)
Hot water drips from the
spout
During heating, water will come out of the outlet. The overflow from the
tank is being drained. This is not a malfunction. When heating the water
has finished, the overflow drainage will stop.
The “Heating” light is off
Once the water in the tank is heated up, the “Heating” light will turn off.
There is a sound when
water is on, water comes
out with air inside
When the water inside the tank is heated there will be air inside the tank
(the air and steam that have dissolved into the water).
When the water is on, because there is air mixed with the hot water, there
may be a sound, or the flow may be inconsistent.
Hot water has a foul odor
This is probably the odor of plumbing adhesives, cutting fluid, or similar
residue from construction. The odor is more noticeable as the water is
heated and temperature increases. The odor will gradually go away with
use.
The flow of water turns off
after a short time even when
holding out your hand (*)
This product is designed to spout water only for 10 seconds.
Water does not turn off
within 15 seconds of taking
your hand away (*)
If water droplets or debris cling to the surface of the sensor during use,
the water may continue to come out even if you take your hand away.
In this case, the learning function* will shut the water off after it comes
out for approximately 15 seconds. Please wipe off the water droplets or
debris.
The following problem do not mean the product is
malfunctioning
