Code Description Cause
The flow rate requested by
the gel timer exceeded the
max flow rate (26 cycle per
pump)
Bad level sensor(s)
Tank low on material
Loose/broken connection
Bad level sensor(s)
Defective fill valve
Defective fill valve
No material is actually being
fed
Loose level sensor
connection
Bad level sensor
The number of pump cycles
since last reset has
exceeded the limit
The number of dispense
Valve cycles since last reset
has exceeded the limit
Pressure exceeds
user-defined limit
Solution
Reduce the flow rate so that the
gel timer flow rate is below the
max flow rate
Replace level sensor(s)
Fill tanks with material
If the tanks appear to have plenty
of material, check to make sure
the level sensor(s) is connected
to the proper port and that the
cord is not damaged
Replace level sensors(s)
If the tanks appear to have plenty
of material, check to make sure
the level sensor is connected to
the proper port and that the cord
is not damaged
Replace fill valve is leaking
Replace level sensor
Make sure the feed pumps are
operating properly
Check for loose or disconnected
wires or plugs
Replace level sensor
Performed desired maintenance
and reset the pump cycles in the
maintenance screen.
Performed desired maintenance
and reset the pump cycles in the
maintenance screen.
Inspect for leaks in fluid path.
Increase operating pressure by
increasing flow rate and/or
restriction in the hose and valve.
Decrease user-defined pressure
limit.
