If you did not turn the unit OFF and unplug. it before changing the filter, do so now.Just repeat the process, but make sure the master ON/OFF Switch is OFF and the unit is unplugged before removing and replacing the filter. Be sure the filter is properly installed.Wait at least 5 minutes, before plugging the unit back in and Turning the Master ON/OFF Switch to ON. That should give the electronics time to rest themselves.
