Flux Sensors - 

If trigger connection points cannot be established, the magnetic field readers (82.23.1) may be used in 

place of the trigger board and cable. The magnetic field readers or flux sensors connect directly to the control board in 
the trigger wires spots as shown on the wiring diagram. The magnetic field readers or flux sensors can be placed on 

wash motors or rinse valves to measure a magnetic field when the motors or valves are activated which will trigger the 
proper pump or valve on the dispenser. 

 
 
 
 

 

 

 

1.

 

Connect the wash trigger (white and brown wires) to the appropriate wash trigger output (between 24 and 480 
V 50/60Hz) as recommended by the dish machine manufacturer. 

2.

 

Connect the rinse trigger (black and red wires) to the appropriate rinse trigger output (between 24 and 480 V 
50/60 Hz) as recommended by the dish machine manufacturer. 

3.

 

Make sure to connect the earth ground (green wire) to the ground connection on the dish machine as 
recommended by the dish machine manufacturer. 

Main Power should be applied any time there is power to the dish machine. The main power cable will come out of the 
conduit fitting with the trigger cable and be hooked up near the same electrical connection point on the dish machine. 

If there is ever any question about the main power or trigger cable connection to the dish machine, please check 
with the dish machine manufacturer to see where the proper trigger connection points are located before 
installing the trigger connection wires.

(Some models may not include all items listed below) 

Symptom Probable 

Cause

Remedy 

No power is being supplied 
to the unit 

1.

 

Trigger Cables connected to the wrong 
place on the machine. 

 

2.

 

Switch on bottom of unit is turned off. 

 

3.

 

Power is not cycling on the machine 
properly. 

 

4.

 

Trigger/Power cable is damaged from 
installation. 

1.

 

Check wiring diagram for proper connection and 
contact dish machine manufacturer for correct 
trigger placement. 

2.

 

Make sure switch is turned on. 

 

3.

 

Check with the dish machine manufacturer if all 
power should have been restored to the unit to see 
if there is an issue with the machine. 

4.

 

Turn power to the dish machine off and inspect the 
cable for any possible damage done. 

Pumps are not priming like 
they should be or not 
holding a prime 

1.

 

Hole in the tubing from the chemical 
container to the pump head. 

 

 

2.

 

Hole in the squeeze tube in the pump 
head. 

3.

 

Fitting is not tight on the tubing 

1.

 

Check the tubing from the chemical container to 
the pump head for leaks by feeling the tubing for 
chemical that has leaked out. Replace the tube if 
necessary. 

2.

 

Replace the squeeze tube after inspecting it for a 
possible hole or leak. 

3.

 

Check both the inlet and outlet fitting and tighten if 
necessary to create a good seal. 

Pump over feeding 

1.

 

If in concentration or probe mode, 
feed rate may not be set correctly. 

2.

 

If in concentration or probe mode, 
probe cable may not be connected 
properly. 

3.

 

If a probe is being used, scale could be 
built up on the probe. 

4.

 

Range of set point is too low. 

1.

 

Check the programming for the feed rate. 

 

2.

 

Check the probe cable connection points and make 
sure it is connected properly. 

 

3.

 

Clean Probe. 

 

4.

 

Check set point in programming. 

Pump under feeding 

1.

 

If in concentration or probe mode, the 
probe cable may be shorted. 

2.

 

If a probe is being used, scale would 
be build up on the probe. 

3.

 

Range of set point is too high. 

1.

 

Check the probe cable for any possible shorts and 
correct the issue where necessary. 

2.

 

Clean Probe. 

 

3.

 

Check set point in programming. 

Rinse/Sanitizer pump not 
running 

1. Speed turned off. 

1. Check the programming to see the speed setting 

and make sure it is on the proper setting.
