4.10.2 TEMPERATURE CALIBRATION TEST
4.10.2.1 Models 6400/6500, 6700/6900, 6905.
During the Relay/Triac output test (Refer 4.10.1) the program and option LEDs form a bar graph display indicating the tem-
perature of the door thermistor. See table below.
Note: A thermistor resistance of 1K7=113°F water temperature.

An open circuit thermistor or temperature sensed below 32°F - all program and option LEDs are to turn on.
A closed circuit thermistor or temperature sensed above 210°F - all program and option LEDs are to flash at a 0.5 second
on 0.5 second off rate.
4.10.2.2 Models 6600, 6605, and 7000.
During the Relay/Triac output test, (Refer 4.10.1), If the temperature calibration point of 113°F is reached, then Smart Dry LED
will illuminate on 7000 series machines, alternatively the WASH CYCLES LED will illuminate on Rotary machines (provided
Door Thermistor monitoring was selected).
If an open circuit thermistor is detected, (temperature sensed is below 32° F), then the indicator LED will flash at a 1 second on,
1 second off rate.
If a short circuit thermistor is detected, (temperature sensed is above 210° F), then the indicator LED will flash at a 0.5 second
on 0.5 second off rate.
Notes: No other thermistor temperatures are displayed.
A door thermistor resistance of 1K7W = 113°F water temperature.
4.10.3 WATER LEVEL SENSING OPERATION
Models 6400/6500, 6600, 6605, 6700/6900, 6905 ,7000 Series.
During the Relay/Triac output test (Refer 4.10.1) the RINSING LED, (RINSE ONLY LED on 7000 series), (or the WASH
CYCLES LED on Rotary machines, provided Water Level monitoring was selected), will indicate the water level in the
dishwasher.
IF the second level pressure switch, or the under sump switch, activates the drain pump, (i.e.. Overfill detected),
THEN the indicator LED will Flash at 1Hz.
ELSE
IF the Pressure switch circuit is open, (water detected),
THEN the indicator LED will be constantly illuminated.
ELSE
the indicator LED will not be illuminated, (i.e.. Water not detected).
Note: Overfill can not be detected while the drain pump is activated.
