Edition/Revision 0-A Tuesday, May 11, 1999
NOTE: You will need a T20 Torx screwdriver and may need #1/ #2 flat blade screwdrivers
and a pair of needlenose pliers. Many parts can be snapped out without using tools.
HINT: Symbols for parts (e.g. "
f3" or "e6 ") refer to schematic diagram #36 on page E-1
and #48 on page E-2.
NOTE: The following parts can't be serviced from the front of the dishwasher (the dishwasher
must be pulled out and the tank removed or tilted/blocked up to replace them):
• Heater
• Circulation motor
• Aqua sensor ("Sensotronic")
• NTC (temperature probe)/Hi-Limit (185
o
F) thermostat
NOTE: On SHU/I 43/53/68 models, run test program to identify dishwasher problems (see
test program guide on page F-1). The test can run more than one hour (to get
temperature up to 150
o
F), but tests can be cancelled to greatly shorten testing time.
The test program allows draining, filling, circulating and heating to be checked more
quickly than running a standard wash cycle.
To use test program for troubleshooting, measure voltages/currents as parts come
on. For example, run heating test and measure current coming into dishwasher – if
current ≈ 11A, Hi-Limit, heater and flow switch are OK. If not, check each part to see
which one failed. This test saves time since you can't get to these parts without
removing the tank and can't run resistance checks from front of dishwasher because
flow switch stays open. Please see page B-1 on using test program to troubleshoot
heater, flow switch and Hi-Limit.
NOTE: To cancel/drain dishwasher while it's cycling, press and hold the following buttons
(until dishwasher starts to drain):
G SHU/I 43-- & SHV 43/48
G Depress and hold "Regular Wash" & "Power
Scrub Plus" buttons
G SHU/I 53/68
G Depress and hold "Scrub Wash" &
"Delicate/Economy" buttons until "CL"
shows on display
NOTE: Jumpers aren't included with replacement modules. For SHU/I 43/53 models, take
jumper off old module and put it on new module.
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).
