Introduction
The GE models WNCJ2050 and WNCK2050 introduce
SmartCard technology to the GE commercial laundry
line. SmartCard technology allows commercial laundry
establishments and customers to conduct commercial
transactions without hard currency. This technology
uses a memory chip based card that can store all the
necessary transaction information and provides the
consumer great convenience and flexibility. The
SmartCard system also provides owners of commercial
establishments improved security and added managerial
features as well as greater flexibility.
To use the card, the user would insert the card into a
special central vending station along with a money
deposit that will credit the SmartCard. The machine
encodes credit for the amount of money deposited onto
the card. The user then takes the card to the washer,
inserts the card and selects the wash cycle. Based on
the cost of the cycle, the card reader in the washer
deducts that amount from the card. When the total
amount on the card has been used, the card is inserted
back into the vending station where additional credit
may be added to the card for the amount of money
deposited.
GE Washer WNCJ2050 and WNCK2050 contain a
SmartCard reader located to the right of electronic
Control Panel. WNCJ2050 uses the BridgePoint Smart-
Card control reader. WNCK2050 uses the ESD SmartCard
control reader. A keypad electronic washer control has
been added to the model line to improve ease of use
and serviceability. The main wash functions are still
accomplished through a two-speed motor, hot and
cold water valves and a pump. The components are
controlled by the electronic control, the dual pressure
switch, and the keypad selector switches. The L3D
electronic control consists of a printed circuit board,
transformer and housing.
As detailed in the product warranty, the SmartCard
control reader is serviced by the reader’s original
equipment manufacturer. In cases where the field
service diagnostics indicates the error code EO (serial
communication – external), the user should contact the
reader original equipment manufacturer for service at
the following numbers:
Model WNCJ2050 BridgePoint: 1-800-562-5875

TO REDUCE THE RISK OF
ELECTRICAL SHOCK:
• The power must be disconnected before servicing by unplugging the
machine or disconnecting the circuit breaker.
• The machine must be electrically grounded through the grounding
lead in the three-prong power cord. The cord must be plugged into a
properly installed and grounded appliance outlet. If local codes
require an additional ground connection, use a 16-gauge or larger
wire to connect the washer cabinet to an established ground. In all
cases the grounding method must comply with all local codes and
ordinances.
