Troubleshooting 

Symptom Probable 

Cause 

Remedy 

Proportioner 
fails to draw 
chemical 
properly. 
 

1.  Insufficient water supply pressure.  
2.  Safelink cap has chemical build-up 

(if installed). 

3.  The outlet tubing might be pinched 

closed. 

4.  Chemical metering tip is clogged. 
5.  Mineral deposits are built up in the 

in the proportioner. 

1. 20 PSI is the minimum allowable 

pressure.   

2. Soak in hot water to clean. 
3. Straighten out the tubing to remove the 

restriction. 

4. Remove metering tip from check valve 

and replace with new one. 

5. Soak proportioner in delimer or off the 

shelf product such as CLR to clean 
mineral deposits. 

“Air Gap” 
Proportioner is 
dripping or 
spraying a mist 
(fan pattern) of 
water. 

1.  Mineral deposits are located on Air 

Gap nozzle. 

1.  Soak nozzle and inlet screen in delimer or 

off the shelf product such as CLR to clean 
and remove mineral deposits.   

Water valve is 
not shutting off 
completely. 

1. “Sliding lever” return spring may be 

missing on Remote Fill gun. 

2. “Sliding lever” is not returning all 

the way down due to interference 
between the sliding lever and either 
the chemical supply and/or outlet 
tubing. 

3. Bucket fill outlet hose is catching 

the bottom edge of the sliding lever 
during normal usage. 

4. Bottle Fill valve will not shutoff. 
 

1. Remove cover and visually check for 

sliding lever return spring.  Replace if 
missing. 

2. Remove cover and visually check for any 

tubes rubbing the sliding lever.  Routing of 
chemical supply and outlet tubing must not 
restrict the movement of the sliding lever.  
Reroute tubing. 

3. Don’t pull the bucket fill outlet hose too 

tight from either side otherwise sliding 
lever may not return properly. 

4. Make sure bottle fill hose is not pressed 

against the lever. 

Water valve is 
leaking. 

1.  Barbed nut is too loose.  

 

1.  Shut water supply off first.  Hand-tighten 

the barbed nut.  Do not over tighten w/tool. 

Threaded 
connections 
are leaking 
water. 

1.  The connection between the 

dispenser and water supply line is 
too loose or rubber washer is 
missing. 

2.  Backflow prevention devices 

and/or proportioners are too loose. 
 

1.  Shut water supply off first.  Carefully 

tighten the female hose coupling on the 
dispenser to the inlet water supply line.  
Do not over tighten. 

2.  Tighten loose connection(s) with tools if 

necessary.  Do not over tighten if using 
tools. 

Selector valve 
is not selecting 
the correct 
chemical 

1.  The transmission assembly is 

malfunctioning. 

1.  Make sure the transmission is engaged 

with the selector valves. If problem 
persists, replace transmission assembly. 

Water is 
leaking in 
between the 
two water 
valves 

1.  Plastic fitting connecting the water 

valves has lost its seal. 

1.  Remove the plastic fitting and apply 

silicone grease to both O-rings and 
reattach to the valves.
