Note: All errors can be manually reset by pressing Stop/Resume when the error message is shown, or by cycling
power applied to the pump after the error has occurred. Under certain circumstances, the "Drive overload" error can
only be reset by cycling power applied to the pump. If the troubleshooting steps listed above do not help to resolve
the error condition, then the problem may be internal to the motor/drive. Contact Hayward Technical Service at
(908) 355-7995 for additional assistance.

Indicates that the DC bus voltage has risen above 400 VDC. Verify that line voltage is
within 10% (207-253 VAC) of pump rated voltage at the terminal block.
Indicates that the DC bus voltage has dropped below 230 VDC. Verify that line
voltage is within 10% (207-253 VAC) of pump rated voltage at the terminal block.
Also, verify that power supply connections are properly made at the circuit breaker
as well as at the terminal block.
Indicates that the internal components of the drive have become overheated. Motor
airflow path should be checked for obstructions and cleared if present. Check
ambient temperature and verify against motor nameplate (50°C/122°F).
Indicates that motor current is too high. Check impeller, diffuser, shaft seal, and
motor for any issues or binding.
Indicates that the drive was not able to start the motor. Check impeller, diffuser,
shaft seal, and motor for any issues or binding.
Indicates that one of the motor phases is open and that the motor/drive may need to
be replaced. Contact Hayward Technical Service for additional assistance.
Indicates that there is a problem with the processor in the motor/drive, and that the
motor/drive may need to be replaced. Contact Hayward Technical Service for
additional assistance.
Indicates that there are communication problems between the user interface and
motor/drive. Connections between the user interface and motor/drive should be
verified.
Indicates that the drive memory has been damaged or corrupted, and that the
motor/drive may need to be replaced. Contact Hayward Technical Service for
additional assistance.
Indicates that there are communication problems inside the motor/drive, and that
the motor/drive may need to be replaced. Contact Hayward Technical Service for
additional assistance.
Indicates that the user interface is receiving an error from the motor/drive that it
does not understand. Contact Hayward Technical Service for additional assistance.

Questions and answers
I have Hayward variable speed pump (pool) MAXFLO VS(TM) looks like timer is not following real time. If I **** trying to modify current time does not show save option, Controller does not start any time program, message shows no timers are set. Is that problem fixable, or controller must be replaced?
The timer issue on the Hayward MaxFlo VS 500 variable speed pump may be fixable by adjusting the settings in the Timer Menu. If the pump was previously controlled by a mechanical time clock, it should be connected directly to the power supply, bypassing the clock. If the issue persists and troubleshooting does not resolve it, the problem may be internal to the motor or controller, which could require replacement.

How can I run my Hayward VS pump in manual mode? (I just want to be able to push a button to start and stop and not have to reprogram anything). MY pool company installed a pump and now I cannot use my remote. TH pump id for a waterfall in the pool
