• To test the electronic coin counter and the locking-type door interlock (monthly), perform

all of the following steps, in order. Do not skip any step.

Step 1. Make sure that power is ON to your machine.

Step 2. Close the door. Do not insert coins.

a. If the machine starts, let it run to the end of the cycle, then proceed to Step 3. (This may
have been simply a restart in mid cycle—when electric power is restored after a power
interruption while the machine was running).

=^cT ) Step 4 tests the possibility of a free wash simply by closing the door and Step 5 tests the
possibility of a free wash when electric power is restored after a power interruption while the machine
was not running.

b. If the machine does not start, proceed to step 3.

Step 3. Open the door. Now verify that the machine will not accept coins with the door open.

a. If the machine accepts coins when the door is open, take it out of service, determine why,
and fix whatever is wrong. (Perhaps the door switch is bad or the door switch actuator is
jammed making the switch think the door is closed.) Do not return the machine to service
until it successfully passes all seven steps described herein.

b. If the machine does not accept coins with the door open, proceed to Step 4.

Step 4. With the door open, manually operate the door switch actuator 100 times (Figure 1).
Operate the actuator for one second ON (depressed), then one second OFF (released). If the
machine completed steps 1, 2, and 3 successfully, this tests if simply closing the door will permit
a free wash.

a. If the machine starts while the door switch actuator is depressed, immediately take your
hand off the door switch actuator and take the machine out of service until the coin
counter has been changed. Do not return the machine to service until it successfully
passes all seven steps described herein.

b. If the machine does not start, proceed to Step 5.

Figure 2: Wall Mounted Power Disconnect Switch

Step 5. With the door closed and the machine still in the “unarmed” condition (it has not yet
accepted coins), turn the power ON and OFF 25 times at the wall-mounted power disconnect
switch (Figure 2) or external circuit breaker. Turn power ON for five seconds, then OFF for five
seconds). Observe if the machine starts at any time the power is turned ON. This tests if the coin
counter will give a free wash when electric power is restored after power interruption while the
machine was not running.
