Troubleshooting Chart:
* In hard water areas, scale may form inside the discharge end of the eductor, as well as in other areas of the unit which 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.
1. No discharge
a. No water
a. Open water supply
b. Magnetic valve not functioning
b. Install valve parts kit
c. Excessive water pressure
c. Install regulator if water pressure exceeds
4.14 bar (flowing)
d. Eductor clogged
d. Clean* or replace
2. No concentrate draw
a. Clogged foot valve
a. Clean or replace
b. Metering tip or eductor has
b. Clean (descale)* or replace
scale build-up
c. Low water pressure
c. Minimum 1.76 bar (with water running)
required to operate unit properly
d. Discharge tube(s) not in place
d. Push tube firmly onto eductor discharge
or flooding ring missing from
hose barb; ensure inner discharge tube
inner discharge tube
is installed and has flooding ring.
e. Concentrate container empty
e. Replace with full container
f. Inlet hose barb not screwed
f. Tighten, but do not overtighten
into eductor tightly
g. Clogged water inlet strainer
g. Disconnect inlet water line and clean
strainer
3. Excess concentrate draw
a. Metering tip not in place
a. Press correct tip firmly into barb on
eductor
b. Chemical above eductor
b. Place concentrate below the eductor
4. Failure of unit to turn off
a. Water valve parts dirty or
a. Clean* or replace with valve parts kit
defective
b. Magnet doesn't fully return
b. Make sure magnet moves freely.
c. Push button stuck

6. Water discharge from air
a. Restricted discharge hose
a. Ensure discharge tube is not immersed,
vents on eductor
kinked or elevated. Ensure there is no
liquid in the discharge tube when begin-
ning to operate dispenser
b. High water pressure
b. Install pressure regulator if
flowing water
pressure
exceeds 4.14 bar
