Opened pool yesterday and let pump run all night. Just shut pump off a little while ago and put multiport into backwash mode and immediately my cheap blue hose popped up so I shut the pump off. I fixed the hose and tried to start over but I couldn't get it to backwash. No water coming out. When I turn the valve to filter I get nothing. Only setting that seems to work is waste. Do I have a bad valve? The spider was changed last season could it be worn or dislodged?
Thanks
