Recall Of Stored Error Codes

Whenever an electrical system fault is detected by the main control unit, one or more error codes are displayed and
stored by the control unit. If desired, the error codes (if any) from the previous operation of the machine can be recalled
for troubleshooting purposes. To recall the last stored error codes, perform the following steps:
1. Turn the Key Switch (A) to the off position.
2. Press and hold the Solution/Pre-spray Switch (C).
3. While holding the Solution/Pre-spray Switch, turn the Key Switch to the on position.
4. Continue to hold the Solution/Pre-spray Switch until the pre-spray indicator is green.
5. Release the Solution/Pre-spray Switch.
• If there were previously no error codes stored, the display will show a wrench icon with a "-" next to it, and the
scrub off indicator will be red.
• If error codes were stored, the display will now show the wrench icon and the stored code(s)
6. To keep the error codes in memory, turn the main Key Switch to the off position.
7. To clear the stored codes, press and release the Scrub OFF Switch (H). The display will now show a key icon.
8. Turn the Key Switch to the off position.

Turning Fault Detection On or Off

Factory Default: ON
Normally the main control unit will perform checks of the electrical system during operation. If a fault occurs in
a particular system, that system (and possibly others) will be shut down. This can make troubleshooting the
system difficult. This option will allow service personnel to disable some of the fault detection checks to facilitate
troubleshooting. This will not disable the over-current protection on any of the systems. To turn the fault checking on or
off:
1. Turn the Key Switch (A) to the off position.
2. Press and hold the Scrub OFF Switch (H) and the Solution/Pre-spray Switch (C).
3. While holding both switches turn the Key Switch to the on position.
4. Continue to hold both switches until the pre-spray indicator is yellow.
