4.10.7 OVERFILL TEST
Models 6400/6500, 6600, 6605, 6700/6900, 6905, 7000
Series.
This test is used for checking the operation of the second
level pressure switch or under sump switch circuits as part of
an off line audit. The test involves turning on the fill valve until
the control senses that an overfill fault condition has occurred
(drain pump running). Then the control is to display the overfill
fault code (not to be saved in memory) and turn off the fill
valve.
Access the Field Test Cycle. Refer Section 4.10.6
For Push-button control models:
While in step 4 (FILL), press the Water Temperature Button,
the fill valve will then turn on, (time limited to 3 minutes).
For Rotary control models:
While in step 4 (FILL), turn the HEAT OPTIONS knob such
that the position indicator is pointing towards the Heat
Options LED, the fill valve will then turn on, (time limited to 3
minutes).
For all models:
Pressing and holding down the Start/Cancel button for 3
seconds at any stage, is to return the control to the stand-by
state, by turning off all LEDs, then draining until 30 seconds
after the first level pressure switch detects empty.
4.10.8 Fill level
For best performance, check the fill level of your dishwasher.
Once the dishwasher is fully connected, run it through a
complete Rinse Only cycle to ensure it is emptying and filling
correctly. For low water pressure situations run Rinse Only
cycle 3 times. Half way through the final Rinse Only cycle,
pause the dishwasher and check the water level inside the
dishwasher. If the water level is not above the minimum water
level (marked on the lower spray support tower), increase the
fill level.
1. Ensure the dishwasher is not running though a cycle.
Depress the Water Temp button for ten seconds until the
buzzer sounds.
2. Press the Start/Cancel button to select fill time, as per chart
(factory setting is 65 seconds). Continue to press the Start/
Cancel button until the desired indicator is illuminated.

time.
