Softener not draining brine water from salt storage tank!


I have a Kenmore Ultrasoft 100 water softener Model # 625.725112 which is not draining the water from the salt storage tank even after I cleaned all the nozzle/venturi parts, housing and else 2-3 times.

I checked all the parts and the flow plug which sits in the housing (HVDC) looks worn out. Could that be a problem?

Also I have been using the softener for the last 6 years or so but never used any raisin bed cleaner. Would cleaning that with a raisin bed cleaner help?

Also just like you sanitize the softener before you start using it, you put some bleach in the brine tank. Can I do the process again (after all the salt is gone from the tank) and use CLR instead of Bleach? The water in my area is very very hard and I'm sure I have blockages at several places.

Thanks and I'll be waiting for your response with all the details!

Thank you for your question.

I am sorry you are having a problem with the water softener. I see that Anna T has given you a few links to look over. I recommend following the advice in the second link. Jimmy has given great diagnostic information. If you are confident that the nozzle and venturi is clean and the flow plugs are clear I recommend replacing the seal kit. I will post the instructions for replacing the seals below.

Just remember to turn the water supply off first.

Turn the water supply off to the softener.

Unplug the softener

Remove the plastic covers.

Remove motor mount and gear

Remove the clip for the drain

Remove the screws securing the valve cover. A burst of water will come out, I recommend wrapping a towel around the valve body. This will keep the water from spraying.

Remove rotor and the seals from the valve cap. Make sure you remove two seals. Sometimes the small seal will stick in the cover.

Lube and install the new seals on the rotor and place into the valve cover.

Then remove each seal one at a time. Lube the replacement seal and install it. That way you will not get confused on what seal goes where.

You have a cylinder in the valve body that has a spring on the underside. Remove the cylinder and slightly stretch the spring. This helps the sealing of the seal.

Once all of the seals are replaced you can reassemble the softener in the reverse order.

After you have completed the repair, push and hold the regenerate button. This will start the softener in a cycle. While the softener is running check for water leaks. If you spot any leaks, turn the water off immediately and repair the leak.

Do not use anything other than resin cleaner, to clean the resin bed.

Please let me know if you have any other questions.

If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:

Thank you Mark for your very helpful response and thank you Jimmy for posting the link as well. I'm confident I could change the seals myself and I'm gonna change the HVDC flow plug as well as I read somewhere if it's worn out, it's not gonna help create the pressure. Thanks again and hopefully these things will do the trick. Thanks!

Please let me know know how this works. Another tio is to look at the face of the rotor. the face that rubs on the seals. If it is scored it should be replaced also. Thanks Mark.
