Key SHU/SHV/SHI dishwasher parts have been changed for the “softer bearing” upgrade for index #
UC/11 for all models. This made the dishwashers quieter through suspending the circulation pump
by flexible bands instead of mounting it onto the base. The key parts changes are shown below,
including part #’s and model #’s parts are used on. Please note these changes to order the correct
parts for each dishwasher model/index #. All other component assembly parts and part #’s
(drain pump, circulation pump impeller, circulation pump motor capacitor, water inlet valve,
NTC, base, etc.) are the same as before.

CAUTION: Although the new base can be used interchangeably with new or old parts, the parts themselves
cannot be used interchangeably. A new pump, sump or heater assembly must be replaced by new parts and
cannot be used with the old pump, sump and heater assembly. Similarly, the old pump, sump or heater
assembly must be replaced by old parts and cannot be used with the new pump, sump and heater assembly.

Using # 264946 Front Cover to Replace Broken # 266746,
# 263832 or # 264461 Control Module Buttons
NOTE:The #
264946 front
cover fits on all
three modules -
- the # 266746,
# 263832 and #
264461.
1st Edition/Revision 3Wednesday, May 9, 2001
# 266746, # 263832 or # 264461 control modules are often replaced when
buttons break, not for electronic failures. Replacing the # 264946 front cover
when buttons break instead of replacing the entire control module will save
customers time and money.
HINT: When customers
report broken buttons on their
dishwashers, the cause is
almost always broken tabs on
the front cover. The white or
black buttons on the fascia
panel and the control module
keypad rarely fail.
NOTE: The # 264946 front
cover has a short lead time
while control modules have
long four month lead times
(from Germany). Using the
cover to replace broken
buttons will avoid delays in
obtaining parts.
HINT: Use the # 264946 front
cover instead
of replacing an
older 263832 module with a
266746module to save
customers time and money.
Many 263832 modules have
been replaced merely for
broken buttons.
NOTE: To determine which control module you have, check the model #’s on the following list:
266746
-- SHU 5302/5304/5305/5306/5312/5314/5315/5316/6802/6805/6806 UC 11 - UC/12, SHU 5307/5317 UC/12
and SHI 6802/6805/6806 UC/11 - UC/12.
263832
-- SHU 5302/5304/5305/5306/5312/5314/5315/5316/6802/6805/6806 UC 06 and SHI 6802/6805/6806 UC/06.
264461
-- SHU 4302/4306/4312/4316 UC 06 - UC/11 - UC/12 and SHI 4302/4306 UC/06 - UC/11 - UC/12.

CAUTION: Insert display module board carefully to
prevent breaking spring locking tabs on front cover.
When installing display module, carefully
slide top of
board into top of front cover, making sure board is
fully seated into tabs. Then, carefully
rotate bottom
of board into position so spring locking tabs spring
back and lock without cracking or breaking. DO NOT
FORCE bottom or top of display board into position.

CAUTION: Some pc board components are sensitive to static electricity and can be damaged by personnel through
touch or close proximity. Personnel handling pc boards should be grounded.
Note cracks in plastic locking tabs.

Soldering # 266746, 263832 or 264461 Control Modules for SHU/I 43/53/68
& GM 915-710 Dishwashers
(excepting SHU 4322/4326)
Occasionally, a heater relay terminal soldered to a # 266746, 263832 or 264461
control module pc board can burn. Heater relays can be resoldered to save
customers time and money. Please follow these instructions carefully
when
resoldering a heater relay terminal.
HINT:Soldering irons give
superior results compared to
soldering guns - using an iron
with a small tip (~ 25W) reduces
possibility of damaging pc
board.
DETAILED INSTRUCTIONS:
1.Carefully clean burned terminal with a small piece of extra
fine sandpaper, taking care not to scratch pc board.
2.Use an iron with a small tip
. Heat soldering iron up to
temperature. Coat tip with small amount of solder.
3.Using rosin core 60/40 solder
, hold tip of hot iron to
terminal and briefly
touch terminal with solder. Don’t use
excessive amount of solder to avoid damaging pc board.
4.Pull iron from terminal and let solder joint cool.
5.Inspect solder joint -- a good solder joint should be shiny,
not dull. If solder joint is dull, carefully resolder.
6.If joint is sound, carefully clean finished joint with a clean
cloth. Carefully remove any lint from pc board.
7.Reinstall pc board to control module, then reinstall control
module to dishwasher. Check dishwasher and make sure
it operates properly, including how it heats.
1st Edition/Rev. 1Wednesday, May 9, 2001
CAUTION:
!
!!
!Do not overheat solder joint -- pc board can be damaged by excessive heat. Make sure
soldering iron is fully heated before soldering and keep heating time as short as possible.
!
!!
!Use rosin core
60/40 solder when soldering pc boards as acid core can etch pc boards.
!
!!
!Do NOT
resolder if relay terminal or pc board is damaged -- replace entire control module.
!
!!
!To avoid overheating pc board, use a moderately sized soldering iron (~ 25W).
Burned board -- showing burned
terminal on back of pc board.
Good board -- showing proper soldering
on back of pc board.
HINT: The heater relay is the
largest
of three relays in the center
of the pc board & can be one of
two colors:
Black
Orange
CAUTION:Some pc board components are sensitive to
static electricity and can be damaged by personnel through
touch or close proximity. Personnel handling pc boards
should be grounded.
