2 INSTALLATION
2.1Pre-Install checklist
□Unpack unit. Retain packing material until installation is successful. Remove packing material from inside the dishwasher.
□Inspect parts to ensure you have all the necessary materials.
□Flush household hot water supply for at least two minutes.
□Measure the enclosure area. The opening must be at least 34" (87 cm) high and 23-5/8" (60-61 cm) wide.
□The opening must be close enough to the sink for water line and drain hose plumbing access.
□Unit must be installed close enough to the sink so that drain hose length does not exceed 92" (234 cm) and a high loop is raised at least 20" (51 cm) above the floor.
□Wooden openings must be sanded smooth and metal openings must be covered by a protective gasket.
□Is your water heater set at 120°F (49°C) and does water pressure measure 15-145 psi (1-10 bar)?
□If installing in a corner, the dishwasher door must clear cabinet hardware.
□Determine mounting method based on dishwasher model and countertop type, whether top or side mount.
2.2Alignment
Gently rest the unit on its back, taking care not to crush the drain hose. Remove the toe panel(s). Loosen front feet slightly. Remove junction box cover and retain for later use. Place dishwasher upright, then level side to side and front to back.
If your dishwasher has pre-attached mounting brackets and you have a wooden under-counter, position brackets as far apart as possible by sliding them within slots in direction of arrows. Do not attach them to the countertop yet.
If your dishwasher has pre-attached mounting brackets and the counter top is stone, use pliers to rotate bracket flanges to remove brackets from the top. Grasp brackets with pliers at perforation and bend until the rounded end breaks free. Discard the ends. Slip brackets through side slots. Using pliers, bend bracket flanges so the brackets will not slip through slots. Do not attach them to the countertop yet.

Disk
Models with water switches need stronger circulation pumps (# 437345) with separate motor starters (# 182318). Circulation pumps, heaters & sumps for water switch / non-water switch models can’t be interchanged.
4.1.4Circulation pumps
Bosch dishwashers use separate circulation and drain pumps to reduce overall size, noise, vibration and energy consumption. This allows the use of tall tanks, increasing overall space inside dishwashers where full-sized plates can be placed in both upper and lower racks. Circulation pumps are suspended by rubber straps to further reduce noise and vibration.
Depending on features, dishwashers have one of four types of circulation pumps. Pumps use different controls, wire harnesses, heaters & sump filters, so replace with identical replacement pumps.
