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.
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.
The look of the escutcheon and insert is unchanged.
Shown below is a table of features in the new controls.

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
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.
