AutoPilot Pool Pilot Soft Touch ST-220 Troubleshooting Guide

What is your Pool Pilot Soft Touch ST-220 telling you?

  • Service Light with Single RED Flash & Flow-Ok Light is Off:

    • In this error mode the Pool Pilot Soft Touch is NOT producing chlorine due to a flow related issue. Please refer to our Pool Pilot no flow troubleshooting guide.
  • Service Light with Double RED Flash:
    • In this error mode the Pool Pilot Soft Touch IS producing chlorine however it is a warning that the system needs attention to prevent a complete loss of chlorine production. Please refer to our test instructions provided below to diagnose the system.
  • Service Light with Triple RED Flash:
    • In this error mode the Pool Pilot Soft Touch is NOT producing chlorine due to low amps. Please refer to our test instructions provided below to diagnose the system.
  • Service Light with Quadruple RED Flash:
    • In this error mode the Pool Pilot Soft Touch ? ? ?
  • Low Salt Light:
    • This is indicating that the unit has detected that salt has dropped below 2400 ppm. Check salt level and adjust to 3000 ppm to ensure that chlorine is able to be produced.
  • Add Salt Light:
    • This is indicating that the unit has detected that salt has dropped below 2000 ppm and the unit is not able to produce chlorine at this low level. Check salt level and adjust to 3000 ppm to start chlorine production.

Pool Pilot Soft Touch Diagnostics Mode:

  • If your unit is providing a service light with double or triple red flashes you will want to perform the test below and provide us with the results for troubleshooting by our technical staff:
  1. If the unit is not already in “boost” mode you will want press the “boost” button and allow the system 60 seconds for boost to activate fully before moving on to the test instructions provided below.
  2. Accessing the diagnostic mode: Press and hold BOTH the up and down arrows at the same time. Hold them pressed until the output display lights go out, leaving just the bottom light illuminated (approx. 5 seconds). You will want to make note of these test results. You can e-mail or call us for tech support based on these details.
  3. The first value to be displayed is the salt concentration in Parts Per Million (PPM). This value is measured by counting the number of flashes of the top 3 lights. In the case of salt, the top light is not used, the next to the top flashes the 1000’s digit and the third light flashes the 100’s digit in ppm.
    Example: 2 flashes/pause/8 flashes/pause Read: 2,800 PPM
  4. The second value is the water temperature in degrees Fahrenheit. When this is displayed, the second light from the bottom is on. The top light flashes the 100’s digit, the next the 10’s digit and the next the units of temperature.
    Example: 8 flashes/pause/6 flashes/pause Read: 86 Degrees F
  5. When the third light from the bottom is on, the cell voltage is displayed. The top light is not used. The second light flashes the 10’s digit and the third the units of voltage.
    Example: 2 flashes/pause/8 flashes/pause Read: 28 Volts
  6. When the fourth light is on the cell current in amperes is being displayed. The top light displays the 10’s digit (not normally used), the next the units and the third the tenths of amps.
    Example: 5 flashes/pause/5 flashes/pause Read: 5.5 Amps
  7. Now that you have your test results you can e-mail or call us with the results for technical support.
