Troubleshooting

Circulation Pump

–

Replacing Impellers (2)

Occasionally, a circulation pump will jam when debris gets caught inside
(when the sump filter wasn’t tightened down) or when a dishwasher hasn’t
been used for months. Often circulation pumps are replaced when merely
changing the

impeller

(kit #

167085

item # 24

) will solve the problem.

“Softer bearing” circulation pump

supported by rubber straps

impeller

Sump

8mm nutdriver

access to

impeller

spacer

“Old” style circulation pump

supported by rubber bushings

CAUTION:

When replacing an

impeller, install the black spacer
between the pump motor and the
rear pump housing.

Failure to do so

may lock up the pump and
damage the rear pump housing!

HINT:

When

replacing an
impeller, instruct the
customer to tighten
the sump filter
properly to avoid
future problems.
