NEW ELECTRONIC CONTROL
The short door electronic dishwashers feature a new electronic control that replaces the sequence switch and control
on previous models with a synchronous detergent trip motor
and a control with relays on the main circuit board.
The look of the escutcheon and insert is unchanged.
There are two different controls–one for sensor models and
the other for non-sensor models.
The control for use on sensor models is a WD21X10197. This
looks similar to the control used on the Triton XL and stainless
steel line of dishwashers. However, the controls are not
interchangeable. The keypad is now a separate part, but
functions and looks the same as the keypad on the previous
integrated control. There are two keypads used: WD21X10198
and WD21X10199.
WD21X10197
WD21X10198 and
WD21X10199
The control used on the non-sensor models is a WD21X10195.
This control looks similar to the WD21X10100 used on the
previous non-sensor models.
WD21X10195
Shown below is a table of features in the new controls.

Please note a service mode feature is now included in the
control. This functions much like the Service Mode on Triton
XL dishwashers. Pertinent sections of the respective minimanuals are attached to this Bulletin for reference.
Also note that previous short door electronic models had a
feature that allowed customers to open the detergent cup by
pressing the start pad three times with the door unlatched.
This feature is not available on the new controls. The Owner’s
Manual mentions the availability of this feature on page 14 or
13 respectively. Be aware this is incorrect. The Owner’s
Manuals have been corrected.
Early production sensor models do not flash the washing light
or any other light on reset. The Owner’s Manual says the
washing light should flash on reset. The programming in the
control will be modified to include this feature beginning with
September 2004 production. A reset on non-sensor models
will cause the Start/Reset light to flash for 90 seconds.
