First check the eductor assembly. Top of valve under chrome plate. Pull it out and clean it (after bypassing and depressurizing the system)
If that is OK the the brine piston will need to be replaced. There is a rebuild kit for this series valve that is about $120 that includes the refill piston and a retrofit kit. It would be wise to rebuild the valve.

Try cleaning the filter screen under the metal cover plate. Also check your water supply pressure. Some softeners won't run properly on low pressure.

Hi again Brett, The ejectors they are referring to are the spray nozzles on the bar in the top of the tank. You simply unscrew them and wash them off, don't loose any pieces. The charge is all for labor and know how. Use the link I gave you last time for one of the two manuals and it will show you the pictures of the nozzles. Good Luck to you, this should Fixya!

Solar salt is full of sediment and even stones at times. Al that white scum on top is the reaction between the salt and sediments in solar salt. All that sediment gets drawn into valve during brining and causes many problems. That stuff is cra***. Use either Dura cube or Hardi cube salt and you will not have this problem again. It is available from most water treatment dealers

SOURCE: water softner problem, does not refill water to brine tank
There is .25 gpm flow restrictor in the top of the float assembly, It may have sediment in it. Unscrew the cap on float top and check the restrictor. When you hook it back up run the system to refill (last cycle) hold the float stem down until all the air is purged from float assembly and see if that works. Also the float ball (foam) may have slipped top too far and is shutting off prematurely. If this does not work it is in the valve which has small pistons, diaphrams and springs to control the cycles. Each cycle also has a solenoid which makes these components work. You will not find a service manual for the Mark 50 valves. They are obsolete unfortunately and parts are no longer available. This valve was made for nearly 40 years and was the hallmark of the Culligan line.

SOURCE: Proper Disposal of a Culligan Mark 50 Water Treatment Tank?
If you disassemble the valve completely (all metal parts) the valve itself is delrin plastic and is recyclable along with the brine tank. You may be able to scrap the softener tank. You will have to get all the resin and gravel out of it. Just tip it over take the inlet manifold out and drain the resin into a bucket, take the resin to culligan for disposal.
