Built-in service program

A service program has been built into the
washer. This program should only be used by
qualified service personnel.

Setting service switch

•

Remove the washer top cover.

Remember that the machine is under
power when service program is in use.

•

Move the service switch to the service
program position. (The switch is located on
top of the circuit board next to the ribbon
connector).

This transforms the buttons into a numerical
keypad. Numbers 1-7 are on the wash cycle
buttons, the Extra Extract button is 8 and the
Gentle Wash button is 9. The START button
serves as an ON/OFF switch.

NOTE:

When in service program the number 0
does not exist. Numbers used are 11-19,
21-28 etc.
