If debris has jammed impeller, turn off

remove circulation motor and unscrew
and clean out impeller.
HINT: If impeller is damaged, replace entire
impeller assembly or it won't seal adequately.
!
!!
! Filter not locked down
securely, allowing debris to
enter sump.
!
!!
! Twist and remove filter, then remove
debris from sump. Instruct customer to
twist and lock filter (cylinder) securely
into sump.
CAUTION: Use caution when
removing debris from sump to avoid
being cut by sharp debris such as
aluminum can tabs or broken glass.
HINT: Due to high temperature rinse (161
o
F)
breaking down food debris and triple filtering
system trapping food debris, filters shouldn't
normally clog up. Problem often caused by filter
not being securely locked down. Instruct
customer to twist and lock filter (cylinder)
securely into dishwasher sump.
HINT: Water level will
not affect washability as
water fill is measured by
pressure, not time –
water level cannot be
adjusted.
