Diagnostic Test Enter the Diagnostic test mode: First: Entering the secure mode by pressing the SECURE key for three (3) seconds. Then press the SECURE key again for three (3) seconds to exit the Intro secure mode. Second: Press DELAY and SANI RINSE keys simultaneously to start the Diagnostic test mode. - Page 35 Diagnostic Test All LEDs on the dishwasher will turn ON for about 15 seconds then turn OFF. • • Temperature measurement is taken one (1) minute after the circulation Pump is ON and immediately after the Heater turns OFF. • At the end of the test the In Process LED will be ON indicating that the Diagnostic test passed. •...
- Page 36 F-1 Drain Failure Cause: Pressure switch is in the closed position after two full drain procedures. Intro Effect: Three long beeps. F-1 will be displayed only during the diagnostic mode. Solution: Press cancel key twice to reset this fault. Possible failure to the pressure switch, drain pump, or restricted in the drain hose.
- Page 37 F-2 Over Fill Condition Cause: Inlet valve does not close. Effect: Three long beeps. F-2 will be displayed to the user and in Intro diagnostic mode. Drain pump will be on until door is opened. Solution: Press cancel key twice to reset this fault. Possible failure to the inlet water valve or control board.
- Page 38 F-3 Low Inlet Water Pressure Cause: Low inlet water pressure. Effect: Three long beeps. F-3 will be displayed to the user and in Intro diagnostic mode. Solution: Press cancel key twice to reset this fault. Possible failure to flow meter, Inlet water valve, or restriction in main water feed.
- Page 39 F-4 Wash Process Sensor (WPS) Failure Cause: No response signal from the WPS. Effect: Wash cycle will go into a default time table. F-4 will be Intro displayed during the Diagnostic Only. Solution: Possible failure to WPS sensor or related wiring.
