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.

264461.
1st Edition/Revision 3 Wednesday, 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 266746 module 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.

Service Bulletin
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.

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.
