Line C will show any fault observed from previous cycles. The faults will be identified as
1-6 and are detailed below (multiple faults may be active at the same time):
Fault 1: Indicates the horizontal float switch did not close during the initial fill.
• Open the door and check the water level. If low, turn machine off then
back on to start an additional fill cycle.
Fault 2*: Indicates the vertical float switch has activated and the machine is overfilled.
• To clear this fault verify the water level and remove the standpipe.
• Attempt to drain the machine by cycling power on then off.
• If the machine is not overfilled, manually trigger the float switch and verify
status of input on PLC.
Fault 3: Indicates the horizontal float switch opened for more than 5 seconds.
• Allow cycle to complete to determine if fault 3 clears.
• If not, open the door and verify the standpipe is fully seated, strainers are
in place, and water level is low.
Fault 4: Indicates Sanisure was active for the maximum wash cycle time.
• Verify incoming water meets minimum temperature and pressure specification.
• Adjustment of rinse tank differential set point may be needed (see screen #7).
• Not applicable for AVENGER LT-E Models.
Fault 5: Indicates fault 4 has been activated for 5 consecutive cycles.
• If fault #5 is active contact technical service for assistance.
• Not applicable for AVENGER LT-E Models.
Fault 6: Indicates the drain cycle has completed and the hortizonal float switch is still
active.
• Verify standpipe is removed prior to turning machine off.
• Verify water level. If high and standpipe is removed verify there are no
clogs in drain line.
* Faults 2 and 5 will prevent the unit from cycling.
