SHU/SHI/SHV Dishwasher Quick Check Chart
1
st
Edition/Revision 0-A Tuesday, May 11, 1999
Use this chart to quickly identify problems from front of dishwasher without removing it.
For a complete troubleshooting chart when symptoms are known, please refer to the
SHU/SHI/SHV Dishwasher Troubleshooting Chart.
NOTE: Use a multimeter with temperature, voltage/resistance and current (ampere) probes.
Do all resistance checks with power turned off. Identify each wire color and location
at the control module before looking at this chart. For a quick reference for
measuring resistances from the front of the dishwasher, please refer to the one page
diagram Measuring Resistances from the Front of any SHU or SHI Dishwasher.
NOTE: To access wire harnesses, open door and remove outer door panel (by removing
three T20 Torx screws on each side of inner door, starting from bottom -- the top six
screws hold the fascia panel to the door). Once screws are out, close door, lift outer
door panel up and pull bottom of panel out – door panel will drop out.
NOTE: Please see circuit diagram #36 for SHU/I 43/53/68 model dishwashers and
diagram #48 for SHV 43/48 model dishwashers in the Major Appliance Technical
Manual.
NOTE: An "F" fault code in the display for SHU/I 53/68 dishwashers shows there's a filling
problem (not filling, overfilling, underfilling or water in the base). The fault code can't
be reset manually – it will reset itself 15 minutes after the dishwasher has been
turned on (after testing how it fills).
To check Measure If yes If no

HINT: Locking type terminals
are used – push a small (#1)
blade screwdriver into each
terminal notch and slide
terminal off at same time.
HINT: Start test program,
start any wash cycle or reset
dishwasher to run drain motor
-- see if water drains.
HINT: The drain motor is not
a bilge pump – it won't
remove water from the
dishwasher base.
