Re: No installer menu found and no settings show to turn on
A two speed pump has the ability to switch between high speed, or a more cost effective low speed. The pump ID Label will indicate if it is a two speed pump, as both horsepower will be listed. Most pumps are one speed pumps.
Low salt would not cause a Check Flow display. This has something to do with not enough water passing through the manifold assembly and activating the flow switch in the tri-sensor assembly. However, insufficient flow can cause a low salt display.
Resolve the flow issue first.
Check pump/skimmer baskets. Check to make sure there aren't any valves redirecting flow from the manifold. Check filter pressure to see if it needs to be backwashed or cleaned.
Regarding a flow issue with the AutoPilot, also check your cell for scale formation within the cell body. Check the manifold base check valve to ensure it is not stuck in the opened position (turn the pump off and see if the check valve closes all the way, then turn the pump ON to see if it freely opens). If it's stuck in the opened position with the pump off, it may be allowing too much water to bypass the tri-sensor.
