Circulation pumps

COMPONENTS

Circulation pumps, heaters & sumps for water switch / non-water switch models can’t be interchanged.

Circulation 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.

BLDC

Pump, motor and control come as one unit (# 665510). Speed changes as needed for wash cycle and washability. Pump is isolated from motor, so there’s no seal needed and no need to loosen or replace impellers.

Float

The float is a safety device which starts the drain pump if there’s too much water in the tank. It doesn’t act like a bilge pump (i.e. it won’t drain water from the base).

If there’s water in the base or the float switch isn’t working, error code E5 is possible.
