Below are two important notes about the diagnostic cycle:

•

Cycle Terminate - At any time during the diagnostic cycle, depressing and

holding the stop button for a minimum of 3 seconds terminates washer

activities and clears the cycle.

•

Injection Signals - The injection signals are not tested during the

diagnostic cycle.

Cycle 31 Sequence - Short Individual Function Test

Close the washer door.

Turn the control key to the PROGRAM mode.

Select cycle 31 using the SCROLL UP/SCROLL DOWN buttons.

Push the green START button.

From this point, the operator must observe the functions of the washer to

ensure correct operation. With the top removed, the activation of each

function can be observed. Each step in this test will turn on an output on the

I/O interface assembly. Each time an output is active, the corresponding RED

LED on the I/O interface assembly will light. The outputs are clearly marked.

To end the test, push STOP and the machine will return to the programming mode

with cycle 31 displayed. The sequence of operation for the diagnostic cycle is

explained below:

•

All indicators are lit and "00" is on the display. No other function of

the washer is active.

•

Push the SCROLL UP button. The display will show 01.

For each number in the test, the function will be active momentarily when the

START button is pushed and released. The function can be held on indefinitely

by pushing and holding the start button for 3 seconds. Use the SCROLL UP to

move from one function to the next.

•

Step 1 - Lock the door.

•

Step 2 - Turn on thermoactuator #1 (lock).

•

Step 3 - Turn on thermoactuator #2 (unlock).

•

Step 4 - Close the drain valve.

•

Step 5 - Turn on the cold water to the tub.

The pressure switch low level setting can be tested at this point.

The drain valve is closed and cold water is on for as long as the

START button is pushed. When the water level reaches a low level,

the water valve will turn off and no additional cold water can be

added. (The time required to reach a low water is dependent on input

water pressure. It may require several minutes.)

•

Step 6 - Turn on the cold water to the dispenser.

The pressure switch low level setting can also be tested with this

step. For details see Step 5.
