4.1.4.4 BLDC (UC/46 through present)
Pump, motor and control come as one unit (# 665510). Speed
changes as needed for wash cycle and washability (Vario wash).
Pump is isolated from motor, so there’s no seal needed and no
need to loosen or replace impellers.
4.1.5 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 (except for models where E5 = motor speed
error).
4.1.6 Drain pump
Drain pumps are mounted to sumps in the front of dishwashers --
they’re easily accessible from the front of dishwashers by
removing toe kicks.
4.1.6.1 Pump specifications
Drain pump is rated 120V, 60 Hz, 35W, 0.85A.
4.1.6.2 Solving installation issues
Often improper installations, not drain pump issues, cause
dishwashers to not drain properly.
• Must have drain hoses with high loops (min. 20” high) or
drains with air gaps.
• Drain hoses are 6’ long and can be up to 10’ long. Drain
hose extension kit SGZ1010UC/01 (76.75”) is available.
• Secure drain hoses to rear of dishwashers with non-metal
bands.
