High Level Still Made
— The machine will not increase the speed from drain speed to extract
speed if the high-level input (MTA3-8) is grounded. This input grounds when the high-level
switch is closed. If the controller sees the high-level input when extract speed starts, the machine
will ignore the extract step and decrease the speed without power.
Look for a blocked pressure hose to the level switch or a broken level switch.
Door/Inverter Fault
— This error indicates one of three conditions:
•
the operator selected a formula before closing the door,
•
the door opened while the machine was operating, or
•
the inverter sensed a fault during operation.
Door/Inverter Fault Before a Formula Starts
— You must close the door before selecting a
formula. If the door is open when you press one of the
Formula Selection
buttons, the controller
recognizes an error condition.
1. The controller prevents further operation for a safety delay period of 100 seconds.
2. If you close the door, the
In Progress
light and the
Last Rinse
light flash simultaneously.
3. After the safety delay period, the lights continue flashing until the you press the
Terminate
button (
) to clear the error.
4. The lights stop blinking after 10 minutes unless you clear the error. The error is cleared only
when you press the
Terminate
button.
Door/Inverter Fault During Operation
— When operating normally, the inverter closes an
internal contact wired in series with CRDL pins 5 and 8. If the door is closed and the inverter is
functioning, the input on MTA3-5 is grounded, as described in Door Open. If the inverter senses
a fault, its internal contacts open and the input on MTA3-5 is lost. This same input is also lost if
the door opens during operation. Refer to the inverter documentation for specific troubleshooting
procedures.
As happens when the door opens during a formula, the microprocessor signals the error by flash-
ing both the
In Progress
light and the
Last Rinse
light simultaneously. Both lights flash
on
for
two seconds, then
off
for two seconds, repeating for 10 minutes. After 10 minutes, both lights re-
main off.
For safety, all machine controls are disabled for 100 seconds after the error occurs. To open the
door after this error:
1. You must first wait 100 seconds until the controls are enabled.
2. When the controls are enabled, press the
Terminate
button (
) to clear the error.
3. Finally, hold the
Door Unlock
button (
) and unlatch the door.
If the error happens again after you close the door, contact an authorized maintenance person.
After correcting any error with the inverter itself, start the formula again.
