Rheem Insufficient Flow Rate / Incorrect Speed Programming

Pump runs but pool water remains cloudy or dirty despite apparent circulation.

Possible Causes

Rheem variable‑speed pump programmed at too low RPM, Clogged filter reducing effective turnover, Bypassed or partially closed valves around filter, Oversized pool relative to programmed run time

How to Fix / Troubleshooting

Safety First: Turn OFF pump before adjusting valves; programming changes can be made with power on.

  • Increase speed and run time: On Rheem variable‑speed models, raise the RPM during filtration cycles and extend daily run time to achieve at least one full turnover of pool volume.
  • Verify valve positions: Ensure water is actually passing through the filter and not bypassing via a heater bypass or recirculate setting.
  • Clean the filter: Backwash or clean cartridges to restore full flow.
  • Monitor pressure and flow: Adjust speed until you see strong return flow and appropriate filter pressure.
