I have a 2 speed pump and a timer with the orange tabs to control run time. There are dip switches that are supposed to control how long the pump runs on hi speed before switching to low speed. The low speed has been over riding the hi speed when both switches are in auto. I can get hi speed to work, but have to have low speed switch on off and hi speed on manual. I replaced the dial timer and still have the same problem. Do the dip switches need to be replaced as well or where should I look for the next step to correct the problem?
