Fault Description Troubleshooting Action
8 1, 4 Solution solenoid overload
1. Check for a wiring problem.
2. Check coil resistance (see below).
3. Replace solenoid if coil is shorted.
11 NA Chemical pump overload
1. Check for a wiring problem.
2. Replace pump.

Mode
Solution solenoid open
1. Check for disconnected solenoid wiring plug, open in
wiring, or open in solenoid (see below).
2. Repair or replace.
Voltage at control board should be -24V referenced to B+.
37 NA Chemical pump open
1. Check for disconnected plug or open in wiring.
2. Repair or replace
When the pump is On, it makes a clicking noise.
If the board output is correct it should appear as a pulsed
signal to a DVM.
62 4, 2 Solution solenoid control fault
1. If J3-11 is 24V referenced to B+ when Solution switch is
Off, replace control board.
2. If J3-11 is 0V referenced to B+ when Solution switch is Off,
disable fault via Hidden Menu. Refer to “Control Board J1,
J2, and J3 Pin Outs and Test Points” section.

Troubleshooting Solution & AXP/EDS System Issues
Problem Possible Cause
Inadequate or no solution flow No solution in the tank.
Red Solution Shutoff Valve (21) is in the Off position .
Clogged Solution Filter (20), valve L1, or hoses.
L1 Solution Solenoid Valve defect.
Main controller fault.

Solution tank level indicator shows empty even
though the tank is full
Small clear hose at pressure sensor on control board is kinked - refer to “Replacing the
Operator Control Panel“ for instructions.
Solution flow and/or chemical rate don’t appear to
follow programming
1. Air leak at hose connection to pressure sensor.
2. Air leak at Pressure Sensing Tube fitting.
3. Small clear hose at pressure sensor on Interface Control Panel is kinked.
Solution level indicator doesn’t work after new
control board installed
1. Solution tank wasn’t completely drained before installation of new Interface Control
Panel. Completely drain the solution tank and the pressure differential should work
properly again.
2. Check for air leaks at re-connected hose fittings.
Chemical rate doesn’t match manufacturer
specifications
Check that pump is wired correctly and that the polarity isn’t reversed.
