SOLID STATE CIRCUIT BOARDS
7.4 Circuit Board Test Points and Connectors
Tools:
The following tools are required to perform checks on the circuit boards:
• Standard set of hand tools
• Volt/Ohm meter (VOM) Sensitivity: 20,000 ohms/volt
Special Tools:
The following special tools are recommended:
• Magnet, P/N 111026, door magnet (Available from Champion), or comparable
• Touchpad/Display, P/N 112621 (Available from Champion)
• Jumper wire with miniature alligator clips to check water level probe (Supplied by others)
Connecting the VOM for Voltage Checks:
Refer to the illustration at right and follow
the instructions below to make voltage
tests on the circuit boards.
1.
Molex harness connectors must be
plugged-in to the male connector
on the board for voltage checks.
2. Input and output AC voltages are
approximately 120VAC.
3. Connect one VOM lead to chassis
ground.
4. Carefully insert the other VOM lead
into the wire end of the connector until
it contacts the metal pin in the molex
connector.
5. The exposed pins on the male portion
of the connector are insulated with a
protective coating. Do not attempt
to scrape the coating off the pins.
BEFORE YOU BEGIN TESTING A CIRCUIT:
DON’T FORGET !!
If the dishwasher POWER pushbutton is pressed when the machine is ON, the dishwasher will
automatically enter the auto-shutdown mode.
If the main incoming power is interrupted while the dishwasher is powered ON from the
POWER pushbutton, then, after the main incoming power is restored, the dishwasher will
auto-fill when the POWER pushbutton is pressed.
Refer to page 59, The Dishwasher Has Overfilled, if you encounter an overfilled condition
during test procedures.
Refer to Section 7.3.2, pages 56-57 and Section 7.3.4, page 57, for the description of LED status
lights on the solid state circuit boards.
