Interior LED Lighng (some models)
This test will check the wiring to the LED tub lights and the
lights themselves. The following items are part of the LED Tub
Lights circuit.
n Harness/Connecon
n LED Tub Lights (3)
n Control Board
NOTE: Under normal operaon...
• The Interior LED Lighng is not on during the wash cycle.
• The Interior LED Lighng turns on when the wash cycle is
complete and remains on for 15 minutes.
• The Interior LED Lighng turns on when the door is opened
and remains on for 15 minutes.
Test Procedure
NOTE: The three (3) LED Tub Lights are wired in series. If one
light malfuncons, the enre light circuit will not funcon.
1. Open door to dishwasher. The Interior LED Lights should
turn on. The following steps assume that this step was
unsuccessful.
2. Unplug dishwasher or disconnect power.
3. Remove toe and access panels to access control board.
4. Visually check that the P13 connector on the control is
securely installed.
¾ If visual passes, go to step 5.
¾ If the connector is not inserted properly, reconnect and
retest Interior LED Lighng.
5. Disconnect P13 from the Control Board.
6. Measure each LED light individually using the diode check
seng on the mulmeter. Meter should display a numeric
reading from anode to cathode and “OL” reading from
cathode to anode (refer to strip circuit below).
¾ If LED check passes, go to step 7.
¾ If any of the LEDs do not pass the check, replace the
defecve LED individually and retest Interior LED
lighng.
7. Set voltmeter to DC and connect red lead to P13-1
and black lead to P13-4 on the control board. Plug in
dishwasher or reconnect power.
8. Measure for 13 VDC between P13-1 & P13-4 with lights
disconnected and door opened. Light output must be
measured within 15 minutes of opening the door.
¾ If 13 VDC is not present, replace the control and retest.
¾ If 13 VDC is present, proceed to step 9.
9. Unplug dishwasher and disconnect power.
10. Reassemble all parts and panels.
11. Plug in dishwasher or reconnect power.
