Care and cleaning
Filters
Inspect and clean the filters periodically. This should be done every other month or more depending on usage. If
there is a decrease in wash performance or dishes feel gritty, this is also an indication the filters need to be cleaned.
The retaining posts can be a
WARNING
choke hazard for small children if
removed from the dishwasher. Keep out of reach
of children.
Ultra-Fine Filter
To clean the Ultra-Fine Filter, remove the bottom rack.
Twist the Ultra-Fine Filter counterclockwise and lift to
remove. Rinse filter with warm soapy water and use
a sponge to carefully remove any stubborn particles.
Scrubbing with scouring pads or brushes can damage
the filter. Once cleaned, replace the Ultra-Fine Filter, and
twist it clockwise to lock in place.
Protect Against Freezing
If your dishwasher is left in an unheated place during the
winter, ask a service technician to:
1 Turn off electrical power to the dishwasher. Remove
fuses or trip circuit breaker.
2 Turn off the water supply and disconnect the water inlet
line from the water valve.
Does Your Dishwasher Have an Air Gap?
An air gap protects your dishwasher
against water backing up into it if a drain
clogs. The air gap is not a part of the
dishwasher. It is not covered by your
warranty. Not all plumbing codes require
air gaps, so you may not have one.

Fine Filter
To clean the Fine Filter (mesh plate), remove the bottom
rack. Remove the Ultra-Fine Filter.
Twist each of the two retaining posts located toward the
back bottom of the tub counterclockwise, and remove the
Fine Filter. Rinse filter with warm soapy water. Scouring
pads or brushes can scratch the filter surface but a soft
brush or sponge may be needed to remove stubborn
soils or calcium deposits caused by hard water. Once
cleaned, replace the Fine Filter and the Ultra-Fine Filter.
Twist the two retaining posts clockwise to lock in place.
3 Drain water from the water inlet line and water valve.
(Use a pan to catch the water.)
4 Reconnect the water inlet line to the water valve.
The air gap is easy to clean.
