The 2-speed pump in my 2006 J385 shuts off after about 25 minutes of use and will not re-start until it has cooled down (this started about 2 months ago and has not gotten worse and has not improved). My pumps have always automatically shut off after 20 minutes. I usually re-start them to relax a little longer and then I leave the pumps on for another cycle as I put dichlor in to sanitize when I am done. Any suggestions?
