If this occurs, take appropriate measures as listed below.
When an error code appears, the display and the operation light will flash

• This is harmless. Small bubbles appear as the air in the
water is heated and depressurized rapidly to
atmospheric pressure.
• When the unit is under very high pressure, water will leak
from the drain plugs as a safety so that the unit is not
damaged by the high pressure.
• Coloration to a blue color 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.
