WARNING
Electrical Shock Hazard
Electrical Shock Hazard
Only authorized technicians should perform diagnostic
voltage measurements.
Disconnect power before servicing.
Replace all parts and panels before operating.
After performing voltage measurements, disconnect
power before servicing.
Failure to do so can result in death or electrical shock.
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.

For wash/drain motors fuse and triac load fuse.
■ Verify harness connections to all loads and control are made.
■ Check stored failure code and/or operation of loads during Service
Diagnostics Cycle.
Wash/Drain Motor Fuse Diagnostics
If both the wash and drain motors fail to operate, motor fuse may be open.
Check the fuse and replace control if fuse is open. Inspect and check
resistances of both motor loads. If either motor is open, shorted, or shows
evidence of overheating or pinched wires, replace loads and/or repair wires.
■ If only wash or drain motor operates, fuse is OK. Use meter to measure
non-operational motor’s (3) phase resistances.
Triac Fuse Diagnostics:
■ If a phase is open (> 1,000 Ω) or unequal to the others, motor is bad.

Service Diagnostics Cycle
Service Diagnostics Cycle Notes:
1
To invoke the Diagnostics Cyle, perform the following while in standby:
Press Start key to wake up control panel.
■ 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 Cyle 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 Run cycles and options returned to default.
■ Last Run 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.
Turn on all LEDs immediately upon receiving entry sequence (even if
door is open) and throughout this first interval as a display test.
Diverter will be on continuously in interval 14. In all other diverter
intervals, diverter will only be on until it reaches the intended position
for that interval.
Press Hi Temp key in this interval to clear customer error history.
■ If Hi Temp key does not respond, the control panel is in “Sleep
Mode.” Open and close the door to wake up the control panel and
then press Hi Temp to clear the customer error history.
Thermistor (temperature sensor) checks - turn clean LED on if
thermistor is in its normal temperature range (32°F to 167°F [0°C to
75°C]). Turn sanitized LED on if fill temperature is above 85°F (30°C).

OWI (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 interval 15 if
water is detected.
■ Check OWI sensor for presence of bulk soil during pause interval
13 and turn on the Clean LED in interval 12 if bulk soil is detected.
■ Drain until OWI sensor sees the presence of air or a max. of 1:52
during interval 5 and turn on the Clean LED in interval 4 if air is
detected.
■
7
DC Fan Motor is on during upper rack washing intervals.
8
Turn off all LEDs during pause prior to displaying error codes.
9
Pause to allow for cold first fill detection.

Lower spray arm (LSA) models identified by finger-shaped sensor

■ Interval 3: LSA moves to Home position after drain is completed.
Home position = LSA approximately 5° clockwise from 12 o’clock.
Customer Cycle Operation
To quickly advance through customer cycles, invoke the Rapid Advance mode
by pressing HIGH TEMP - HEATED DRY - HIGH TEMP - HEATED DRY, after
starting the cycle. Then, press START/RESUME to advance through cycle
intervals.
NOTE: Rapid Advance mode is automatically enabled in the Service Diagnostic
cycle, but must be manually invoked in customer cycles.

Control Pinout
Meter Check of Loads and Fuses.
Load must be connected for triac to operate correctly.
Meter checks are best made at the control.
Dishwasher Strip Circuits
■
The following individual circuits are for use in diagnoses. Do not continue with
the diagnosis of the appliance if a fuse is blown, a circuit breaker is tripped, or if
there is less than a 120-volt power supply at the wall outlet.
■
Unplug dishwasher or disconnect power.
Perform resistance checks. To check resistance of a component,
disconnect harness leads first.
