INSTALL THE LWI3020 MODULE FOR ALLIANCE/SPEED QUEEN LAUNDRY
MACHINES
Alliance/Speed Queen laundry machines require an LWI3020 module. A single LWI3020 will support both
single washer/dryer machines and stacked dryer machines.
Before installing an LWI3020, verify that the transformer in the machine is the correct
type. The transformer should have 4 Red wires on the secondary side. If there are only
2 wires, then the transformer must be replaced. The correct transformer is (p/n
201375P), and can be ordered from Alliance Laundry Systems through your laundry
supplier.
Disconnect all power to the machines.
1 Remove the operator console (with display and switches) from the machine.
Single machine: remove only the top two screws.
2 With access to the machine’s control board, install the 4-pin connector of the wiring harness labeled P1
onto the (H5) connector of the laundry machine’s control board.
The H5 connector may be either 4 or 7 pin. If the connector has 7 pins, the P1 connector must be
installed on pins 1 through 4.
