CAUTION! Observe the Electro-
static Precautions outlined in Sec-
tion 3. Always wear a grounding
wrist strap when removing or re-
placing PC boards or ICs.
Installation Instructions
NOTE: The following precautions should be taken whenever printed
circuit boards are being handled or replaced:
• Always use an ESD safe container when transporting boards
from one location to another.
• No boards should be removed from their containers except at
an approved static station or where personnel and machine are
properly grounded.
• At minimum, use a wrist strap grounded to the washer when
removing and/or replacing PC boards.
NOTE: Failure to follow the above precautions may result in electro-
static damage to the printed circuit board. If a static discharge
happens to go through an integrated circuit and the transient current
pulse is not effectively diverted by protective circuitry, the current
from the discharge can flow through the board and raise the
temperature of internal junctions to their melting points. Damage can
range from latent degradation to complete destruction.
12. Remove existing EPROM (U5 location) from washer control PC
board.
13. Install new EPROM board in place of the old EPROM just
removed from the control PC board.
NOTE: Stand off must be mounted between upper left corner of new
EPROM board and existing control board to maintain board position.
14. Raise control assembly and secure in position with screws
previously removed.
15. Set unit electrical disconnect switch to ON position. Position
Main Power switch, located on electrical supply box, to ON.
