How to Fix / Troubleshooting

Safety first: Disconnect power before opening the control housing.

  • Factory reset: Follow the AquaJet manual procedure to perform a full factory reset of parameters. This often clears minor memory errors.
  • Reprogram settings: After reset, re‑enter all required speed schedules, timers, and configuration options.
  • Firmware update: If AquaJet provides firmware updates via USB or service tool, apply the latest firmware following their instructions.
  • Replace control board: If E16 persists and the pump cannot be configured, the control board's memory may be defective and require replacement.
