Clock shows “0:00”. • If the power is disconnected for any reason, when the
power is reconnected, the clock on the display screen
shows “0:00”, indicating that it needs to be reset. ( p.13).
The water temperature changes
after a power failure or when the
power is disconnected.
• The temperature setting and the bath fill setting may
both need to be reset after a power outage.
The plastic on the surface or buttons of
the remote controller has torn, peeled,
or air bubbles inside.
• The surface of the remote controller is affixed with a
protective sheet (to prevent surface scratching, etc.) at
time of shipment. This sheet can be removed or left as it
is. When leaving the protective sheet on, areas frequently
touched may tear or peel. However, the remote controller
will not malfunction from water entering such torn or
peeled areas. To restore the appearance of the remote
controller surface, simply remove the protective sheet.
The light on the operation button does
not come on.

The hot water is turbid. • This is harmless. Small bubbles appear as the air in the
water is heated and depressurized rapidly to atmospheric
pressure.
The water appears blue
The bath tub/wash-basin has turned
blue.
•
Coloration to a blue colour may be noticed from small
traces of copper ion contained in the water and fat (furring).
However, there are not problems concerning health.
Coloration of the bath tub/wash-basin can be prevented by
cleaning frequently.
Frequent water discharge from drain
pipe.
(Condensing model only)
• Condensation forms inside the unit during operation and is
discharged from the drain pipe.
