The pump is running and water is circulating in the pool, but when I look into the pump, through the lid, the basket will not completely fill with water. Why?

There are a few possible reasons for this.First, check the skimmer and pump baskets. There may be debris in one, the other, or both that is preventing the water flow.Second, your filter may need back washing.Third, there may be a blockage in the plumbing or in the pump. If you have tried cleaning the pump and skimmer baskets and back washing the filter and the problem still exists, we recommend that you arrange for a Service Technician to call.
