This is under warranty still call Culligan for service. Is it flashing an error code? In the meanwhile unplug the system for two minutes and plug back in, this may reset the controls.

Culligan mc450 constantly dripping through overflow pipe. Any ideas what I should do.?

If it is running at the drain for the softener, it has a bad seal pack and it needs to be replaced. You will need a Culligan service tech for this if you are not handy.

On my Ultra Jet 3 th power lights keep flashing?

Count the number of flashes IE 3 flashes a pause then 3 flashes this is a error code and tells the tech what the problem is. Without knowing the number of flashes I cannot help. If you have your owners manual there should be a page for error codes somewhere near the joystick page
