GE ZDT870SIFII - Manual (Page 22)

Inspect and clean the filters periodically. This should
be done every other month or so 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. Ultra-Fine Filter
To clean the Ultra-Fine Filter, remove the bottom rack.
Twist counterclockwise and remove the Ultra-Fine
Filter. 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 clockwise to lock in place.
Fine Filter
To clean the Fine Filter (mesh plate), remove the
bottom rack. Remove the Ultra-Fine Filter.
Twist counterclockwise each of the two retaining
posts located toward the back bottom of the tub, 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, the
Ultra-Fine Filter, and twist clockwise the two retaining
posts into place.
WARNING!
The retaining posts can
be a choke hazard for small children. Keep out of
reach of children.
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. The air gap is easy to clean.
1 Turn off the dishwasher and lift off the air gap
cover.
2 Remove the plastic cap under the cover and clean
with a toothpick.
3 Replace the cap and cover when the air gap is
clean.
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.
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.
Check the air gap any
time your dishwasher
