WASHER DIAGNOSTIC CYCLE

The diagnostic test cycle provided with every machine aids the user in verifying

correct operation of the washer after scheduled maintenance and aids the user

in identifying functional problems with the machine.

The diagnostic program, cycle 31, is an individual function test. This program

tests most of the functions of the machine (water valves, drive system, door

lock, etc...). The diagnostic program must be started from the program mode.

The keylock must be in the program position.

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

1. Close the washer door.

2. Turn the control key to the PROGRAM mode.

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

4. 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 when the START button

is pushed and will be inactive when the START button is released. 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).
