* 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.

No Discharge

Cause: No water
Solution: Open water supply

Cause: Magnetic valve not functioning
Solution: Install valve parts kit

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

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.

Water Discharge From Air Vents On Eductor
Cause: Restricted discharge hose
Solution: Be sure discharge tube is not immersed, kinked, or elevated. Be sure there is no liquid in the discharge tube when beginning to operate dispenser

Cause: High water pressure
Solution: Install pressure regulator if flowing water pressure exceeds 60 PSI (flowing)

Excess Concentrate Draw
Cause: Metering tip not in place
Solution: Press correct tip firmly into barb on eductor

Cause: Chemical above eductor
Solution: Place concentrate below the eductor
Excess Foaming in Discharge
Cause: Air leak in pick-up tube
Solution: Put a clamp on tube or replace tube if brittle

Failure Of Unit To Turn Off
Cause: Water valve parts dirty or defective
Solution: Clean or replace with valve parts kit
No Concentrate Draw
Cause: Clogged foot valve
Solution: Clean or replace

Cause: Metering tip or eductor has scale build-up
Solution: Clean (descale)* or replace

Cause: Low water pressure
Solution: Minimum 20 PSI (with water running) required to operate unit properly

Cause: Discharge tube(s) not in place or flooding ring missing from inner discharge tube
Solution: Push tube firmly onto eductor discharge hose barb; be sure inner discharge tube is installed and has flooding ring

Cause: Concentrate container empty
Solution: Replace with full container

Cause: Inlet hose barb not screwed into eductor tightly
Solution: Tighten, but do not overtighten

Cause: Clogged water inlet strainer
Solution: Disconnect inlet water line and clean strainer

No Discharge
Cause: No water
Solution: Open water supply

Cause: Magnetic valve not functioning
Solution: Install valve parts kit

Dead or No Display
Confirm main power connection voltage with a volt meter. Check fuse if optional fuse kit is installed. Substitute transformer followed by the printed circuit board to determine fault.

Excess Detergent Consumption
7.4.1 Probe Mode

Check probe for scaling and measure wash solution via titration kit or by other means. If detergent us at proper concentration, troubleshoot the dish machine for clogged drains, excessive fresh water feedback, etc.

7.4.2 Probe-less Mode

Confirm that initial charge is dispensed only one time per initial fill. if you experience multiple initial charge feeds (Automatic/Conveyor mode only) review initial charge wiring connection. All other modes, adjust initial charge and dose adjustments accordingly.

No Detergent Feed
7.3.1 Probe Mode

Temporarily disconnect probe wire with detergent signal on to force detergent feed.

If detergent feeds, check for probe scaling and check detergent setpoint setting.

If detergent does not feed, substitute pump motor (or solenoid coil) followed by the printed circuit board to determine fault.

7.3.2 Probe-less Mode

Confirm that unit is in a detergent feed condition as determined by rinse/initial charge signal inputs and initial charge/dose adjustments.

If detergent does not feed, substitute pump motor (or solenoid coil) followed by the printed circuit board to determine fault.
No Rinse Feed
Rinse feed is locked out under the following conditions:
Probe-less/Door/Automatic Initial Charge modes – Rinse is locked out after Initial Charge begins until the following rack (rinse signal) occurs.
Probe Mode – detergent signal did not occur within 90 seconds prior to rinse signal (Rinse Saver feature).
If not in one of the above conditions and rinse does not feed, substitute pump motor followed by the printed circuit board to determine fault.

Unit Is Not Pumping Fluid
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)
