Note 1: Pre-Wash Sense Interval
Pressure switch contact closure at any time during this interval causes the
cycle to jump to interval 37. Immediately. For the normal cycle, the heater is
“off” during this interval. For the heavy and pots-n-pans cycles the heater is
“on” during this interval. The power scour option changes this interval to a 16
minute heated wash interval for all 3 cycles (normal, heavy and pots-n-pans).
If the water temperature reaches 140ºF or the thermostat closes. The heater
is turned “off”. Time continues to elapse and all other output states remain the
same until the prescribed interval time has elapsed.
Note 2: Pre-Wash Thermal Hold
This thermal hold is only executed during the heavy and pots-n-pans cycles.
The thermal hold setpoint is 140ºF or thermostat contact closure and the de-
fault time is 25 minutes.
Pressure switch contact closure at any time during this interval causes the
cycle to jump to interval 37. Immediately.
Note 3: Pre-Rinse Sense Interval
Pressure switch contact closure at any time during this interval causes the
cycle to jump to interval 31. Immediately. For the normal cycle, the heater is
“off” during this interval. For the heavy and pots-n-pans cycles the heater is
“on” during this interval. The power scour option changes this interval to a
heated wash interval for the normal cycle. If the water temperature reaches
140ºF or the thermostat closes. The heater is turned “off”. Time continues to
elapse and all output states remain the same until the prescribed interval time
has elapsed.
Note 4: Pre-Rinse Thermal Hold
This thermal hold is only executed during the heavy and pots-n-pans cycles
and only occurs if the pressure switch trips during the sense or thermal hold
intervals of the pre-wash the thermal hold setpoint is 140ºF or thermostat con-
tact closure and the default time is 20 minutes. Pressure switch contact clo-
sure at any time during this interval causes the cycle to jump to interval 31.
Immediately.
Note 5: Main Wash Thermal Hold
This thermal hold is automatic for the pots-n-pans and heavy cycles (set point
= 140ºF). For the normal cycle. This thermal hold is invoked by selecting the
power scour or high temp wash options (Set Point = 140ºF) or as a result of
the pressure switch tripping during the pre-wash (Set Point = 130ºF). For the
low energy wash and quick wash cycles. This thermal hold is invoked by se-
lecting the high temp wash option (Set Point = 140ºF). In all cases, the default
time for this thermal hold is 20 minutes
Note 6: Main Wash Recirculation Interval
The power scour option increases the length of this interval to 10:00 for the
pots-n-pans and heavy cycles.
Note 7: Final Rinse Thermal Hold
This thermal hold is automatic for all cycles except the china wash and rinse
only cycles (Set Point = 140ºF). For the china wash cycle, this thermal hold
only occurs if the pressure switch trips during the pre-rinse (Set Point = 130ºF).
In all cases the default time is 25 minutes.
If the sani rinse option is selected, then the set point for this thermal hold
becomes 150ºF and the default time changes is 25 minutes.
Note 8: Air Dry
The default status for the dry period is heat dry “on”. Selecting the “air dry”
option causes the heater to be turned “off” during this interval.
Note 9: China Dry Interval
When the china wash cycle is selected, the heater will be turned off during this
interval.
Note 10: Option LED’s
When a valid option is active, then the LED for the option will be “on”.
Note 11: Sani Complete LED
When the “sani rinse” option has been selected and completed. A “sani com-
plete” indicator is illuminated at the end of the cycle. During a cycle in which
“sani rinse” has been selected, the target thermal hold temperature for the
“sani rinse” option must be satisfied and maintained. If this condition is not
satisfied (because the final rinse thermal hold default time elapsed or power to
the dishwasher was lost at any time during the remainder of the cycle that
follows due to a door opening or AC line failure) then the sani complete indica-
tor will flash on and off at the end of the cycle. Opening the door or pressing
any key will turn the indicator off in either case.
Note 12: Motor Drain Phase Winding
This output is only “on” when the motor is starting in the wash mode. When
the control has determined that the motor has started, the wash phase wind-
ing will be turned “off”.
Note 13: Motor Drain Phase Winding
This output is only “on” when the motor is starting in the drain mode. When the
control has determined that the motor has started. The drain phase winding
will be turned “off”.
Note 14: Diagnostic Sensor Input Test
The soil sense pressure switch input is active during this interval. Pressure
switch contact closure at any time during this interval causes the cycle to jump
to the next interval. Immediately.
Note 15: Diagnostic Thermal Hold
The default status for this thermal hold is “on”. The thermal hold set point is
140ºF or thermostat contact closure and the default time is 60 minutes. After
60 minutes, the thermal hold is terminated and normal cycle timing resumes.
The diagnostic test cycle advance function can also be used to terminate this
thermal hold.
Note 16: Cycle Complete
A clean indicator will be on at the end of this cycle. Opening the door or
pressing any key will turn the indicator off.
Note 17: Diagnostics Cycle -- Thermostat/Thermistor Indicator
The “clean” LED will turn on during the display test at the beginning of the
cycle (interval 11) and again at the conclusion of the cycle (interval 2) regard-
less of what it detects on the thermistor input. The “clean” LED will be on in
intervals 1 through 8 of the cycle whenever an “open” (resistance greater than
200K OHMS. +/- 50K OHMS) is detected on the thermistor input by the
control. Consequently, if a normally open operating thermostat were to be
installed on the thermistor input, the “clean” LED would be on throughout the
cycle until the thermostat tripped (e.g., during the thermal hold); With a ther-
mistor installed, the clean LED would only be on in intervals 10 and 0. Be-
cause the thermistor always has a resistance of between 50 K-OHMS and 8
K-OHMS under normal operating conditions.
Options
Water Heat:
Forces a thermal hold to occur in the main wash regardless of soil level. The
set point for this thermal hold is 140ºF. This option is automatic with the pots-
n-pans and heavy cycles. It is not available on china wash or rinse only cycles.
Sani Rinse:
Raises the setpoint temperature of the thermal hold in the final rinse to ap-
proximately 65ºC/150ºF. This option is not available with china wash, quick
wash & rinse only cycles. This option is only possible on models that use a
thermistor.
Air Dry:
Opens the circuit to the heater element during the dry period of the cycle. This
option is not available on quick wash or rinse only cycles (which have no dry
period).
Power Scour:
Inserts additional heated wash time into the pots-n-pans, heavy and normal
cycle pre-wash sequence (interval 39 becomes a 16 minute, thermostatically
controlled, heated wash). Turns the heater on in interval 33 of the normal
cycle pre-rinse, invokes a thermal hold in the main wash of the normal cycle
and extends interval 23 to 10 minutes in the pots-n-pans and heavy cycles.
This option is not available on low energy, china wash, quick wash or rinse
only cycles.
