Replacing Impellers (2)
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.

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.
