The pump timer does not start or stop the pump at the programmed times.

Safety First: Unplug the pump before performing a hard reset if recommended by the manual.

• Verify settings: Review the Summer Waves timer instructions and confirm the current time and on/off periods are set correctly.
• Power reset: Unplug the pump for 5 minutes, then plug it back in and reprogram the timer.
• Avoid frequent outages: If your area has frequent power cuts, consider using a manual on/off schedule instead of relying on the timer.
• Control failure: If the timer still behaves erratically, the control PCB or relay is likely faulty, and the control head may need replacement.
