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.

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.
