We have a 24x12x52 Intext pool 8 years old with a salt water system. Been through two salt water systems and NOW all of the sudden the power is on but nothig happens when you try to get the pump working. No humming Nothing! It must be a simple electrical fix which I know nothig about. I took the cover off and everthing look like new inside. Hit the reset several times. Would like to just replace the unit with the key pad but cannot find just that unit. Hate to have to pay 400-500 for whole sand filter etc. Any ideas beside call an electrician? Ty This system is only 2-3 years old.
