Consumer Purge of the Bulk Dispenser Tank
When to Purge the Bulk Dispenser Tank
Only liquid or gel automatic dishwasher detergent
can be used in the dispenser tank. The dispenser
tank must be purged if the consumer puts hand
dishwashing detergent or a rinse agent in the
dispenser tank. These products produce copious
amounts of suds, and water leaks result every time
the dishwasher is run, until the dispenser tank is
emptied.
The dispenser must also be purged if a liquid
dishwasher detergent containing chlorine (like
Cascade Pure Rinse Formula) and one containing
enzymes (like Cascade Complete) have been mixed
in the dispenser tank. When this happens, the
chlorine destroys the enzymes, resulting in poor
wash performance. You can tell if the detergent
contains chlorine or enzymes by reading the
content label on the container.
To purge the bulk dispenser tank (on some models):
1. Make sure STEAM, ADDED HEAT, and HEATED
DRY LEDs are off.
2. Press HEATED DRY button and SELECT CYCLE
button simultaneously for 3 seconds. If done
correctly, all the LEDs illuminate.
3. Press SELECT CYCLE button and ADDED HEAT
button simultaneously for 3 seconds. If done
correctly, the AUTO and LOCK LEDs illuminate.
4. Press START/RESET button one time to exit
service mode.
5. Press START/RESET button to start an auto
cycle and make sure STEAM, ADDED HEAT, and
HEATED DRY LEDs are off.
6. Dishwasher runs a complete cycle with the
main motor instead of the dispenser tank. Cycle
is complete when the CLEAN light illuminates.
This should take approximately 60 minutes.
7. Open door and wipe up the excess detergent
from the door and tub.
8. Pour water on the door and tub where there is
detergent residue.
9. Remove SmartDispense cap and fi ll dispenser
tank with water. Replace the cap.
To remove the positive displacement pump:
1. Remove the outer door panel. (See
Outer Door
Panel
.)
2. Remove 2 Phillips-head screws from the lower
right side of the door edge to release the pump
bracket.
Consumer Purge Cycle
The consumer must enter service mode to activate
the purge cycle. (See
Service Mode
.) The purge cycle
fi lls the dishwasher for 57 seconds, then energizes
the dispenser pump (instead of the main motor)
continuously to drain the dispenser tank.
The purge cycle deselects all other options and
runs for 65 minutes. The consumer should run the
purge cycle 3 times, fi lling the dispenser tank with
water for the second and third cycles. Total time is
approximately 3 hours.
A chemical reaction also takes place between the
chlorine detergent and the enzyme detergent,
which causes the two liquids to coagulate and
build up around the detergent level sensor. This
buildup may prohibit the sensor from sending the
low-detergent signal to the control board, and the
LOW DETERGENT light will not illuminate when the
dispenser tank is empty.
3. Remove the grommet from the inner door panel
and unplug the tube from the reservoir outlet.
4. Disconnect the wires and remove the pump.
