No Discharge
Cause
Solution

No water

 
Open water supply

Excessive water pressure

 
Install regulator if water pressure exceeds 85 PSI (flowing)

Eductor clogged

 
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.

 

 

 

No concentrate draw
Cause
Solution

Clogged check valve

 
Clean or replace

Metering tip clogged

 
Rinse in hot water or replace: DO NOT REAM CLEAN!

Eductor clogged

 
Clean or replace

Clogged water inlet

 
Clean screen
Clogged foot strainer   Clean or replace
Low water pressure and/or volume   Replace with full container
Check valve not screwed into eductor firmly   Tighten, but DO NOT OVERTIGHTEN!

Excess concentrate draw
Cause
Solution

Metering tip not in place (or wrong metering tip)

  
Press correct tip firmly into barb

 

 

Water flow won't shut off
Cause
Solution

Ball valve defective

 
Replace

 

 

 

Leaks at plastic tube
Cause
Solution

Compression nut loose

 
Tighten nut 1/2 turn

 

 

 

Low or no water flow
Cause
Solution

Inlet screen clogged

 
Clean or replace

Supply source inadequate

 
4 GPM flow necessary to operate unit; move unit or replumb incoming line
Scaled eductor or fittings   Clean* or replace

Backflow into concentrate
Cause
Solution

Eductor check valve inoperable

  
Clean or replace check valve

 

 

Discharge from backflow preventer vent
Cause
Solution

Backflow preventer check valve dirty or defective

 
Clean or replace backflow preventer (Kit #105)
Water hammer condition in supply system (cause of "splitting")   Install water hammer shock arresters or water pressure reducing valves
Negative pressure in supply line causing reverse flow   This is the proper operation of this component. Cause of negative pressure must be corrected.
     

 

 

Leaks at plastic and copper junctions
Cause
Solution

Compression nut loose

 
Tighten nut 1/2 turn

 

 

Weak foaming action
Cause
Solution

Clogged water inlet strainer

 
Clean or replace
Water pressure too low   Minimum 25 PSI required
Water temperature too high   Use lower temp water source (Concentrate flow decreases above 140 degrees F water)

 

 

 

Weak spraying action
Cause
Solution

Clogged water inlet strainer

  
Clean or replace
Water pressure too low   Minimum 25 PSI required
