Error code 06 on your Hayward pool pump indicates an over voltage condition, meaning the incoming power supply is too high for the pump to operate safely. This can damage the pump motor and other electrical components. The error typically occurs if your electrical supply is unstable or the pump's voltage settings don't match your home's power input.

How to Fix Error Code 06

  1. Turn Off Power to the Pump

    WARNING: Always disconnect power before working on electrical components. High voltage can cause serious injury or death.
  2. Check the Voltage at the Pump's Terminal Block

    Caution: Work carefully around live wires. If you're not comfortable using a multimeter, call a professional electrician.
  3. Confirm the Pump's Voltage Setting

  4. Test the Power Source Voltage

  5. Inspect Wiring and Connections

    WARNING: Capacitors can store electrical charge even when power is off. Discharge them safely or have a professional do it.
  6. Replace the Pump's Motherboard or Control Board (if needed)

    Warning: Replacing the control board requires opening the pump's electronics. If under warranty, contact Hayward before attempting repair.
  7. Reset the Pump and Test

When to Call a Professional

If the incoming voltage from your breaker panel is over 250V (for 230V) or 125V (for 115V), call a licensed electrician to inspect your home's electrical system. Also call a pool professional if you're uncomfortable testing voltage or opening the pump's electrical box.

Frequently Asked Questions

What does error code 06 mean on a Hayward pool pump?
Error code 06 means the pump has detected an over voltage condition. The incoming power supply is too high, which can damage the motor and electronics.
Can I reset my Hayward pool pump to clear error 06?
Yes, after fixing the voltage issue, you can reset the pump by turning off the circuit breaker for 30 seconds and then turning it back on. However, the error will return if the over voltage persists.
What voltage should my Hayward pool pump receive?
Most Hayward pool pumps are designed for 208-240 VAC (230V models) or 110-120 VAC (115V models). Check your pump's label for the exact rating.
Is it safe to run my pool pump with over voltage?
No. Running the pump with over voltage can cause permanent damage to the motor and control board. It may also create a fire hazard. Always fix the voltage issue before operating the pump.
Why does my Hayward pump show error 06 after a power outage?
A power outage can cause voltage spikes when power is restored. If the spike exceeds safe levels, error 06 may appear. Check the voltage and consider installing a whole-house surge protector.
