Pump will not start at all; no humming, no sound, but power is available at the outlet.

Safety: Isolate power before opening any covers. If unsure, contact an electrician.

• Check external devices: Confirm any time clocks, chlorinators, or automation systems feeding the Onga pump are in ON mode and supplying power.
• Test outlet: Plug in another appliance to verify the outlet is live.
• Inspect pump switch: If the Onga pump has a built-in switch, check for mechanical damage or burning. Replace if faulty.
• Open terminal box: Check that active, neutral, and earth wires are secure. Tighten any loose screws.
• Thermal overload: Some motors have a reset button; allow cooling and press reset if present.

If there is confirmed power at the motor terminals and it remains dead, the motor winding or internal protector is open and the motor assembly should be replaced.
