6. Using an ohmmeter, measure across P9, pins 5 and 6 with
the door closed, strike completely in latch mechanism
(switch closed).
¾ If 3 ohms or less is measured, proceed to step 7.
¾ If high resistance is measured when door is closed,
check for loose connecons and repair as needed.

¾ If reading shows connuity, or door switch is damaged,
replace door switch and retest.
8. Plug in dishwasher or reconnect power.
9. Using a voltmeter set to DC, with door open, verify that
13V DC is present across P9-6 (+13V) and P12-2 (DC GND).
¾ If 13V DC is not present, replace the control.
¾ If 13V DC is present, proceed to step 10.
