PLUMBING PREPARATION
1. In order to reduce running time, Bosch recommends 140° F water inlet
temperature. Your dishwasher will perform equally as well at 120° F water
temperature, but the run time will be extended.
Hot Water Supply
• The hot water line to the dishwasher
must provide between 5 - 120 psi (0.3-
8.27 bars) water pressure.
• The hot water heater should be set to
deliver 140°F (60°C) water
temperature to the dishwasher.¹
• A 3/8” minimum O.D. copper tubing
inlet line is recommended.
• All solder connections must be made
before
water line is connected to the
dishwasher’s inlet water valve.
Do not
solder within 6 inches (152.4 mm)
of the dishwasher’s inlet water
valve.
•
Drill a 1” (25.4 mm) diameter access
hole in the cabinet for the water supply
line (Figure 9A).
• Run the line to the approximate fill
valve location, as shown in Figure 9A.
It is recommended that a shut-off valve (not
supplied) be installed in the hot water
supply line in a readily accessible location,
see Figure 9.
NOTE: If connection to an air gap is
required by local code, air gap kits are
available from local plumbing sources.
Install the air gap according to the
manufacturer’s instructions.
Drain Hose
The dishwasher comes with a seven (7)
foot drain hose.
• A 1.25” access hole must be made to
allow the drain hose to be run to the
drain connection location.
Figure 7
IMPORTANT
If no air gap is used and the drain
line is run into a sink or disposer,
the drain line must be elevated to
a point higher than the highest
water level of the sink to prevent
back siphoning into the
dishwasher.

CAUTION
To protect against possible rupture of
the fill valve, water lines leading to
the dishwasher, as well as water lines
in the dishwasher MUST be protected
against freezing. If the valve or water
line freezes, flooding may occur. Such
ruptures are not covered by the
warranty.
