SOME MODELS.

THIS DISHWASHER IS PROGRAMMED WITH A SERVICE MODE TO AID THE TECHNICIAN IN TROUBLESHOOTING THE DISHWASHER. EACH COMPONENT MAY BE CYCLED TO DETECT IF IT IS FUNCTIONING CORRECTLY. COMPO- NENTS ARE CYCLED BY PRESSING KEYPADS TO THE LEFT OF THE START/RESET KEYPAD. USE THE MATRIX BELOW TO DETERMINE HOW TO CYCLE EACH COMPONENT.

TO ENTER SERVICE MODE :

PRESS KEYPAD #9 AND KEYPAD #3 SIMULTANEOUSLY FOR 3 SECONDS.

TO EXIT SERVICE MODE :

PRESS THE START/RESET KEYPAD AT ANYTIME TO EXIT.

START/RESET	Used to EXIT Service Mode

*NOTE: After 15 minutes of inactivity, the service mode will automatically turn off.

**NOTE: Component will be activated for indicated time. Component may be deactivated by pressing the same keypad that was pressed to activate the component.

TO ENTER F-1 TEST CYCLE:

1.Power up unit.

2.Close detergent cup and latch door.

3.Press KEYPAD #9 and KEYPAD #8 simultaneously for one second. The control will then step through the test automatically.

TO EXIT F-1 TEST CYCLE:

1.Press START/RESET to skip each step until the end.

2.The control will then exit the test cycle, pump out any remaining water and return to normal operation.

F-1 TEST CYCLE MATRIX

STEP	ACTION	LED DISPLAY	DESCRIPTION
1	Start	SENSING and WASHING flash
		for 10 seconds
2	Model Number Display	Combination of KEY 1 (LOCK)	Use KEY 1 (MS3) and DELAY
		and DELAY START 1, 2 or 3	START LEDs to display model
			number in binary for 5 seconds
3	Illuminate Display	All LED’s	Energize all LEDs for 5 seconds.
4	Trip Detergent & Fill	DRYING, SANITIZED	Trip the detergent cup. Energize
			the water valve for 50 seconds.
5	Fill & Circulate	RINSING	Energize the water valve and
			main pump for 10 seconds.
			Close the active vent.
6	Circulate & Heat	RINSING, SANITIZED	Energize the main pump and
			heater for 60 seconds.
7	Calibration	SENSING	All relays and LEDs will be off
			while the processor calibrates
			the turbidity sensor.
8	Circulate & Drain	RINSING, DRYING	Energize the main pump and
			auxiliary pump to evacuate water
			from the unit for 10 seconds.
9	Circulate	RINSING, DRYING, SANITIZED	Energize the main pump to
			circulate water in the unit for
			50 seconds.
10	Trip Rinse Agent &	WASHING	Trip the rinse agent. Read
	Self diagnostics		Turbidity Sensor. Read tub
			temperature sensor. Read
			EEPROM. If diagnostics or turbidity
			errors occur, energize the beeper
			and flash LEDs (see below).
11	Fill	WASHING, SANITIZED	Energize the water valve for 50
			seconds.
12	Fill & Circulate	WASHING, DRYING	Energize the water valve and main
			pump for 3 seconds.
13	Circulate & Heat	WASHING, DRYING, SANITIZED	Energize the main pump and
			heater for 60 minutes.
14	Auxiliary Pump	All LED’s	Energize all LEDs and the auxiliary
			pump to evacuate water for 5
			seconds. Open the active vent.
15	Auxiliary Pump	WASHING, RINSING,	Energize the auxiliary pump to
		SANITIZED	evacuate water from the unit for
			70 seconds.
16	Exit

NOTE: DELAY START 1, 2 & 3 represent the leftmost, middle and rightmost DELAY START LEDs, respectively.

In STEP 10 of the F1 Test Cycle: If the control senses a turbidity sensor error, the control will flash the SENSING LED. If the control senses a tub temperature sensor error, then the control will flash the HEATED DRY LED. If the control senses an EEPROM error, then the control will flash the LOCK LED. If any of these diagnostic errors are detected, the cycle will not advance to STEP 11 until a key is pressed.
