When to Call a Professional
Call a professional technician if the float mechanism appears damaged, if the error persists after cleaning, or if you discover leaks in the water supply lines. Also contact a pro if the float switch itself needs replacement, as this requires electrical connections and accessing internal components.Frequently Asked Questions
