Possible Causes
Failed keypad speed control circuit, Shorted external analog input (if equipped), Faulty control board DAC output
How to Fix / Troubleshooting
Safety: Disconnect power before accessing control wiring.
- Check for external control: If the pump is wired for external analog speed control (0–10V), disconnect the analog input wires and test the pump in standalone keypad mode.
- Test keypad control: With external control removed, attempt to change speeds via the keypad. If the pump still ignores commands, the keypad or control board may be faulty.
- Inspect keypad: Look for stuck or unresponsive speed buttons. Replace the keypad overlay if buttons do not click or register.
- Control board diagnosis: If a known‑good keypad does not restore speed control, the control board’s speed command circuitry is likely defective and requires replacement.
