WARNING
35. WASHER CONTROL
IMPORTANT: Due to the sensitivity of the
electronic control, careful handling is required. As a
precautionary measure, we recommend using a
ground wrist strap when handling the electronic
control. Wrist strap, cord and alligator clip are
designed to carry away any electrostatic charge
from your body and to direct charge to an available
ground. By using this static protection device,
potential electrostatic discharge problems
associated with handling of electronic control will
be minimized. Always handle electronic control by
its metal edges. If a wrist strap is not available,
touch machine while it is plugged in before handling
control to dissipate any charge.
NOTE: New control is supplied in a special anti-
static wrapping and protected by anti-static foam.
While holding control by its metal edges, remove
control from foam and wrapping.
a. Go to rear of unit and remove screws holding
rear panel to side panels of control cabinet.
b. While supporting rear panel, press in on locking
tabs and unplug harness disconnect blocks from
backside of electronic control.
NOTE: DO NOT pull on wires. Instead, hold board
near appropriate disconnect block and unplug by
pulling on disconnect block.
c. Remove four screws holding electronic control
assembly to rear panel. Refer to Figure 7.
d. Place the old control in the anti-static wrapping
that the new control was supplied in.
e. While holding new control by its metal edges,
place control on rear panel and fasten control
down with four screws removed in Step “c”.
Refer to Figure 7.
NOTE: For proper control alignment, tighten the
top two screws first then tighten the bottom screws.
Refer to Figure 7.
f. Follow wiring diagram and reconnect wires to
new control.
IMPORTANT: It is important to take care when
handling the original control. It must be carefully
placed in the anti-static wrapping and anti-static
foam which was removed from new control. If
control is not wrapped properly, warranty credit
will not be issued.
