1. The diagnostics test cycle starts at interval 11 and concludes at interval
2. To initiate the diagnostics test cycle, press the following sequence of
keys within 10 seconds:
High Temp Wash, Air Dry, High Temp Wash, Air Dry
or
Power Scour, Air Dry, Power Scour, Air Dry
The diagnostics test cycle may be manually advanced to the next inter-
val by pressing the pots & pans key. To exit diagnostics, press cancel.
2. The sales demo cycle consists of a single 6-minute wash interval which
starts at interval 1 and concludes at interval 0. To initiate the sales
demo cycle, press the following sequence of keys within 10 seconds:
High Temp Wash, Air Dry, High Temp Wash, Air Dry, High Temp Wash
or
Power Scour, Air Dry, Power Scour, Air Dry, Power Scour
3. The diagnostics test cycle executes a soil sensing interval at interval 9
to test the soil sensing circuit. The sensing LED is illuminated through
out this sense interval.
If the soil sensing pressure switch is tripped at any time during this sense
interval, the control will immediately terminate the sense interval and
proceed with the remainder of the diagnostics cycle.
If the time limit for this sense interval elapses without detecting soil, the
control simply proceeds with the remainder of the diagnostics cycle.
4. The diagnostics cycle suspends cycle timing and executes a thermal
hold at interval 7. The thermal hold interval is terminated and cycle
timing resumes when the water is heated to the desired set point tem-
perature (60ºC/140ºF). The maximum default time limit elapses (1 hour),
or the cycle is manually advanced to the next interval by pressing the
pots & pans key. The water heating LED is illuminated during the ther-
mal hold.
5. The clean LED is illuminated at the end of both the diagnostics test cycle
and the sales demo cycle. The clean LED can be extinguished by open-
ing the door or pressing any key.
6. During intervals 9 through 3 of the diagnostics cycle, the clean LED is
illuminated whenever the control detects a resistance of greater than
approximately 45 K-OHMS on the thermistor/ thermostat circuit. This
feature is intended to help determine whether a thermostat or thermistor
is installed. A thermostat with normally open contacts would trigger the
clean LED (until the thermostat is tripped). Under normal operation, the
resistance of the thermistor is always less than 45 K-OHMS and would
not trigger the clean LED.
7. The wash and drain auxiliary windings are only “on” when the motor is
being started. When the control has determined that the motor has been
started satisfactorily, the auxiliary winding will be turned “off”.
8. Entering the key sequence high temp wash (or power scour), air dry,
high temp wash (or power scour), air dry, after a cycle has started, will
enable the pots-n-pans key rapid advance feature. This will allow ser-
vice to rapidly step to any interval of the currently running cycle.
Other Control Features:
Cancel/Drain:
Terminates current active cycle and clears cycle selections. Executes 2-minute
drain upon first selection if water is likely to be left in sump. Subsequent
selections toggle between 2-minute drains and going to standby.
Control Lock:
The control lock LED is illuminated and all keys of the keyboard are disabled
whenever the control lock feature is invoked by the customer. The control
lock feature (and LED) can be turned on or off by the customer at any time by
holding down the air dry option key for 4 seconds.
Delay Start:
Allows the customer to delay the start of a cycle by up to 6 hours. Each press
of the delay key increases the delay time selection by two hours. The selected
delay period will begin clocking down upon selecting the cycle key. The cycle
selected will begin automatically upon completing the delay period.
Error Messages:
Stuck Key:
If the control detects that a key is stuck in the depressed position, dishwasher
operation will be suspended and the control will flash the LED associated with
that key until the condition is corrected. If a key without an LED is stuck or
multiple keys are stuck, the control will flash the lock-out LED.
