6.1.5 Customer error codes
Dishwashers with digital displays have error codes seen by
customers. Viewing the error code (Display Failure Memory)
chart, the last two columns (under "Customer Failure display")
show error codes seen by customers in the digital display. The
first two columns (under "Customer Service Failure display")
show error codes seen in the error code program. Error code
displays are identical – the only difference being some service
error codes (e.g. E:08, E:16) can't be seen by customers.
6.1.6 Clearing error codes
To clear error codes, run the customer service test program.
6.1.7 Error code E:24 for drain obstructions
If a dishwasher doesn't drain properly and / or shows an E:24
error code, the problem usually is not with the control or drain
pump. To solve the issue, (1) the control must be reset and (2)
the obstructions generating the error code must be cleaned out.
6.1.7.1 To reset the control
1. With the door closed and the dishwasher turned on, press
and hold the Start button for ~ five (5) seconds -- the
display should show "01" or "00". Press the On/off button
(turning the dishwasher off) and the control should be
reset.
2. If step one (above) didn't work, remove the toe kick and
disconnect the drain pump harness from the drain pump.
Make sure the connector isn't touching anything – tape the
connector if necessary. With the door closed, press the
On/off button to turn the dishwasher on. You should hear
the control turn on and control relays click on and off. Wait
about 30 seconds with the power on, then press the On/off

the dishwasher on. The control should be reset.
6.1.7.2 Overly high drain connections

connection lowered, especially for Johnson Tee installations.
CAUTION: For installations with a Johnson Tee, the
Johnson Tee must be installed in the wall behind the dishwasher,
no more than 50" (at it's maximum height) above the floor. The
connection must be ¾" minimum – ½" must not be used.
Dishwasher drain hose extensions must not be used.
