Diagnostic Test Descriptions
Diagnostic Test
This option is used to test various LED lights, water
temperatures, signals, motor directions and relays.
This test is activated by pressing and holding the
COLD keypad with one hand, then pressing the
NORMAL keypad with the other hand.
The Diagnostic Test Routine defines each step of the
test. See Chart 9. Each step will last for five seconds.
When the last step in the table is finished, the
diagnostic routine will restart at the top of the table.
To exit the Diagnostic routine, either press any keypad
or open the washer lid. The control will return to the
“Ready” mode. See Figure 2. If this exit procedure is
not done, the control will start again and go through
the test routine until stopped.
