4 Water Quality

Poor water quality will have an impact on appliance longevity and
may void the manufacturer's warranty. For water analysis data call
your local water department, or if on a well, have well water ana-
lyzed periodically. If water quality exceeds one or more of the values
specifi ed below, Bosch recommends consulting a local water
treatment professional for water softening/conditioning options.
