is the first step in the timer, that timer contacts 0C
to 0T, 1C to 1B, 5C to 5B, and 12C to 12B are
closed, and the speed board will not advance the
timer for 479 minutes.
With the transfer of the timing, the motor speed,
and the motor reversing functions from the timer
to the speed control board, it is important to
understand the coding system to the speed
control board. By using different combinations of
five inputs, the timer can input hundreds of codes.
The speed control board recognizes a code of
line-to-neutral voltage (120 VAC), or 0 at each of
the five input pins. This code would tell the board
to count down for 479 minutes then advance the
timer one step.
Two major differences between the previous front-
load washer and the 2000 front-load washer are:
1. The door lock and switch assembly can be
replaced through the top of the washer. Discon-
nect the two wire plugs by reaching down from the
top, opening the door, and removing the mounting
screws and lifting the door lock out through the
top.
2. The timer can be replaced through the top by
removing the knob and dial, removing the two
screws holding the timer to control panel, and
lifting the timer out through the top of the washer
(see figure above).
Troubleshooting
Attached to the inside of the service panel is the
Tech Sheet with a timer flowchart and a wiring
schematic, which is invaluable when troubleshoot-
ing the washer. The timer flowchart shows which
timer contacts are closed at each step. The sche-
matic shows the electrical connection of the
components.
Using the example of the
Timer Flowchart Sample
on page 15 and the
Schematic on page 21, we
can review how the two work together. On the
timer flowchart at the top of the first column is
CAM, and the numbers below it go from 00 to 14.
These numbers indicate the timer cams. (When
you look at the schematic, each timer contact is
numbered; this is the timer cam number.) On the
timer flowchart at the top of the fourth column is
CONTACT. Below CONTACT are the letters T and
B (Top & Bottom) for each cam number.
On the schematic, each set of timer contacts is
labeled with the cam number and a letter C (Cen-
ter contact), T, or B. On some schematics, the
letter C may be omitted and the contact is labeled
by just the cam number (the C is understood to be
there).
On the flowchart at the top of the fifth column is
CIRCUIT. Below it are different electric circuits
controlled by the timer. Above the rest of the
columns on the flowchart are the washer func-
tions. The column(s) for each function will either
be shaded or blank in line with each circuit. For
example, look at the first column below the 8-hour
delay function. Looking down the column, we see
the block for machine power is shaded, indicating
that timer contacts 0C to 0T are closed. The block
for code C is shaded, indicating that timer contacts
5C to 5B are closed. The block for pressure switch
bypass is shaded, indicating that timer contacts
12C to 12T are closed.
At the bottom of the flowchart is the step time in
minutes and the step number. If we look under the
8-hour delay column, we see 479 in the step time
block and 1 in the step number block. From the
timer flowchart we now know that the 8-hour delay
