Possible Causes
Faulty keypad or speed buttons, Corrupted programming, Drive output stage locked, Automation overriding local control
How to Fix / Troubleshooting
Safety first: Turn off power before opening the control housing if needed.
- Check automation: If connected to a Hayward automation system, verify that external control is not forcing a single speed.
- Manual speed test: Disconnect automation and attempt to change speeds from the local keypad.
- Reset programs: Clear and reprogram speed settings and schedules.
- Inspect keypad: If speed buttons are unresponsive, the keypad may be faulty and require replacement.
- Drive issue: If commands change on the display but motor speed does not change, the drive output stage is likely defective and the drive module should be replaced.
