DISPENSING TROUBLESHOOTING 

 

1.

 

Irregular / Intermittent Dispensing from one side  

 
 

Possible Reason 

Solution 

Too much water pressure.  
Recommend 40 to 60 psi for 
the 

WL100 Water Treatment 

System 

to operate properly. 

Check water pressure at the inlet bulkhead with a water pressure 
gauge. 
 
Additional method of verification is to turn off water to unit and 
press the dispense button.  Does the Solenoid open without water 
pressure to the unit?  Listen for Solenoid to activate, not to 
mistaken for the button “click”. 
 
Adjust water pressure to 40‐60 psi.  

The correct input water 

pressure is critical to the performance of the unit to allow 
Solenoids to open. 

 

Loose or bad connection on 
the Front Dispensing PCB or 
Solenoid Connector 

Check that they are connected properly and tightened. 

Solenoid  

If both the Water Pressure and PCB have been ruled out, then it is 
the Solenoid. 
 
Replace Solenoid. 

Dispensing button is broken on 
PCB 

Check PCB for loose or damaged button.  Replace PCB as 
necessary.
