Dead or No Display
Insure that controller is connected to pump module via J1 cable
Insure that power is connected to pump module
Check to see if the pump module circuit breaker is tripped
Load Count Errors
Quite a number of perceived load count errors may occur in the normal day-to-day operations of a laundry. A load is counted (to the current formula number) each time the highest pump number with a nonzero amount runs. In Relay mode a load is counted each time pump 1 is run.
Load Counts High
Check washer trigger signal for count pump running more than once each load
Load Counts Low
Check washer trigger signals
Check that machine operator may be short cycling the washer
Pumps Don’t Prime
Confirm pump motor harness is connected to PI PCB in pumpstand
Follow pumpstand manual troubleshooting procedures for PI PCB defect
Pumps Don’t Run
When pumps don’t run it is important to differentiate between running on prime and running from a machine trigger. Pumps only run formula amounts from a machine trigger when pumps are calibrated.
When only certain pump positions are defective, check Pump Interface (PI) printed circuit board (PCB) and J1 cable connections.
Only one pump may run at a time in flush mode. Multiple pumps triggered at the same time will run in queue.
No Pumps On Trigger, Prime OK
Are pumps calibrated?
Is a delay time programmed or is pump in cue?
Is there a trigger signal? Confirm by viewing lights on Machine Interface and measuring signal with a volt meter.
Follow pump module manual troubleshooting procedures for MI defect
Test run pump amounts as described in step 5.4.2 or Program Mode

Load Count Errors
Quite a number of perceived load count errors may occur in the normal day-to-day operations of a laundry. A load is counted (to the current formula number) each time the highest pump number with a nonzero amount runs. In Relay mode a load is counted each time pump 1 is run.
Load Counts High
Check washer trigger signal for count pump running more than once each load
Load Counts Low
Check washer trigger signals
Check that machine operator may be short cycling the washer
Pumps Don’t Prime
Confirm pump motor harness is connected to PI PCB in pumpstand
Follow pumpstand manual troubleshooting procedures for PI PCB defect
Pumps Don’t Run
When pumps don’t run it is important to differentiate between running on prime and running from a machine trigger. Pumps only run formula amounts from a machine trigger when pumps are calibrated.
When only certain pump positions are defective, check Pump Interface (PI) printed circuit board (PCB) and J1 cable connections.
Only one pump may run at a time in flush mode. Multiple pumps triggered at the same time will run in queue.
No Pumps On Trigger, Prime OK
Are pumps calibrated?
Is a delay time programmed or is pump in cue?
Is there a trigger signal? Confirm by viewing lights on Machine Interface and measuring signal with a volt meter.
Follow pump module manual troubleshooting procedures for MI defect
Test run pump amounts as described in step 5.4.2 or Program Mode

If the motor is turning check level of drain treatment supply check for air leaks in the supply tubing connection to pump tube stems check for clogs in inlet and outlet tubes insure pump tube is not at all twisted check pump tube. As it wears out, the amount of fluid pumped decreases. Change tube.
If the motor is not turning ensure programmer is functioning: Try to run pump manually (see page 3 of the instruction manual) check program: Be sure both switches are in center position for programmed dispensing check to insure wires from the electronic control to the motor are secure ensure that wire from batteries to electronic control is secure check battery condition. Try new batteries. BE SURE TIMER IS OFF before changing the batteries remove the pump to see if pump is binding the motor (run motor manually — see page 3 of the instruction manual)
Backflow Into Concentrate
Cause: Eductor check valve inoperable
Solution: Clean or replace check valve
Excess Concentrate Draw
Cause: Metering tip not in place (or wrong metering tip)
Solution: Press correct tip firmly into barb
Low Or No Water Flow
Cause: Inlet screen clogged
Solution: Clean or replace
Cause: Supply source inadequate
Solution: 4 GPM flow necessary to operate unit; move unit or replumb incoming line
Cause: Scaled eductor or fittings
Solution: Clean* or replace
* In hard water areas, scale may form inside the discharge end of the eductor, as well as in other areas of the unit that are exposed to water. This scale may be removed by soaking the eductor in a descaling solution (deliming solution). To remove an eductor located in the cabinet, firmly grasp water valve and unthread eductor. Replace in same manner. Alternatively, a scaled eductor can be cleaned (or kept from scaling) by drawing the descaling solution through the unit. Operate the unit with the suction tube in the descaling solution. Operate the unit until solution is drawn consistently, then flush the unit by drawing clear water through it for a minute. Replace concentrate container and put suction tube into concentrate.
