If there is a problem with the unit, a numerical error code will flash on
the remote controller.
If this occurs, take appropriate measures as listed below.
When an error code appears, the display and the operation light
will flash together.
Error Code
Contact Bosch if:
• Any other error code appears.
• An error code is indicated again after the above actions were followed.
• There are any other questions.
Operating Instructions
• This is harmless. Small bubbles appear as the air in the water
is heated and depressurized rapidly to atmospheric pressure.
• 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.
• Condensation forms inside the unit during operation
and is discharged from the drain pipe.
