After your pool filters on the "backwash" setting, you should move it to the "rinse" setting. With the pump off, set valve to rinse. Start pump and operate for about 1/2 to 1 minute. This ensures that all dirty water from backwashing is rinsed out of the filter to waste, preventing possible return to the pool. Stop pump, set valve to "filter", and start pump for normal filtering. If it still won't start, check for restrictions in the intake and discharge lines.
