Fuse Service Check:
F1 = Small-triac load fuse
Check operation of loads during Service Diagnostics cycle.
- ■ If any of the triac loads work, F1 fuse is OK.
- ■ If all triac loads fail to work, F1 fuse could be open. See 'Fuse Resistance Check.'
Fuse Resistance Check:
- Unplug dishwasher or disconnect power.

DANGER
Electrical Shock Hazard
Only authorized technicians should perform diagnostic voltage measurements.
After performing voltage measurements, disconnect power before servicing.
Failure to follow these instructions can result in death or electrical shock.
Voltage Measurement Safety Information
When performing live voltage measurements, you must do the following:
- ■ Verify the controls are in the off position so that the appliance does not start when energized.
- ■ Allow enough space to perform the voltage measurements without obstructions.
- ■ Keep other people a safe distance away from the appliance to prevent potential injury.
- ■ Always use the proper testing equipment.
- ■ After voltage measurements, always disconnect power before servicing.

Meter Check of Loads and Fuses
2. Measure resistance of fuse F1.
NOTE: The fuse is on the bottom of the Control Board but can be checked from the top side. See 'Control Pinout' diagram.
- ■ If resistance is <3 Ω , fuse is OK.
- ■ If resistance is >3 Ω , replace control.
What To Do If Fuse Open:
Inspect and check resistance of all loads on fuse. If any loads are open, shorted, or have evidence of overheating or pinched wires, replace loads and/ or repair wires.
WARNING
Electrical Shock Hazard
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.

Table Caption: This table details the operational intervals, LED status, and component actions of a dishwasher across various cycles and intervals, indicating specific times, sensor checks, and relay activations.
Service Diagnostics Cycle Notes:
- 1 To invoke the Diagnostics Cycle, perform the following while in standby:
- ■ Press any 3 keys in the sequence 1-2-3-1-2-3-1-2-3 with no more than 1 second between key presses.
- ■ The Service Diagnostics Cycle will start when the door is closed.
- ■ To rapid advance 1 interval at a time, press the Start/Resume key. Rapid advance may skip sensor checks as some checks require 2 complete intervals.
NOTE: While you are in the Diagnostic Cycle, the Start/Resume feature is turned off (for example, Auto Resume after door interrupts) and the Start/Resume key becomes an individual advance key.
- ■ Invoking Service Diagnostics clears all status and last run information from memory and restores defaults. It also forces the next cycle to be a sensor calibration cycle.
- ■ Drain and wash motors will pulsate on and off.
- ■ Last Ran cycles and options returned to default.
- ■ Last Ran Delay returns to the lowest delay increment.
- ■ Calibration cycle may force an extra rinse to occur prior to final rinse (to assure clear water), then calibrates the OWI and the fill amount during the final rinse.
- ■ Operating state returns to Standby upon completing or terminating the Service Diagnostics cycle.
- 2 Turn on all LEDs immediately upon receiving entry sequence (even if door is open) for 5 seconds as a display test. Turn off all LEDs for 1 second prior to reporting customer error history.
- 3 Press Hi Temp key in this interval to clear customer error history.
- 4 Thermistor (temperature sensor) checks:
- ■ Turn Clean LED on if thermistor is in its normal temperature range of 32¡F-167¡F (0¡C-75¡C).
- ■ Turn Sanitized LED on if Fill temperature is above 85¡F (29¡C).
- 5 O.W.I. (Optical Soil Sensor) Checks:
- ■ Check OWI sensor for the presence of water during the 5-second pause in interval 16 and turn on the clean LED in
