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.
