4.2 Errors
If your machine encounters an error while it runs a formula, the
formula halts, the operator signal sounds, and an error code dia-
log box (Figure 24, page
See the next section for a list of all the error codes and the possi-
ble causes/solutions.
4.2.1 MilTouch™ Error Messages
The following are error messages the controller can issue, possible causes, and solutions. Opera-
tion stops and cannot be resumed until the cause of the error is corrected. This can require a main-
tenance or chemical technician.
Door Opened — The controller cannot confirm that the door to the washer-extractor is closed.
If this occurs while a formula is in progress, the controller turns off all outputs, cancels the wash
formula, and returns to the Home display.
The Door Opened: Close the door.
Electrical failure: If the door is not open, electrical troubleshooting is required.
Too Long to Fill — The water in the machine did not reach the specified level within the con-
figured Fill Error Time. The controller closes all water valves and turns off all chemical injec-
tions. The Fill Error timer resets after you correct the error.
Fill Time Configured too Short: Do a check of the configured fill time in your machine's
configuration decisions. It may be necessary to increase the fill time.
Low Water Pressure: Do a check of the water pressure and volume to the machine.
Water Valve Malfunctioned: Use the electrical schematic manual to do a check of the
water valves and the circuits that control the valves.
Too Long to Drain — The water in the machine did not drop to the specified level within the
allotted drain time. The controller issues an error but the drain remains open. If a slow drain
caused the error, the error clears and the formula resumes when the transducer senses that the
water level has dropped to the desired level.
Drain Blocked: The drain pipe from the machine to the sewer may be blocked. Check the
drain pipe and remove any obstruction.
Transducer Tube Blocked: The tube from the shell to the pressure transducer
page 29) may be blocked. Check the tube and remove lint or other obstructions.
