Question about Culligan Sediment Water Filter Heavy Duty

1 Answer

My (mark 100 automatic) water conditioner was unpluged for a couple of weeks. Since pluging it back in, it has regenerated every night for the last 10. The salt container is half full and shut off valve is in the operating position. I recently cleaned the salt storage tank, as suggested in the manual. There have been no other changes to explain why its operation like this. Plaese help, losing sleep!

    I have checked the back flush and brine times, but thats about it. The clock was still on the correct time so I did not have to reset that either.

  • foxwood620 Mar 10, 2009

    I understand what you are saying.This particular softener has a sensor in the unit for regeneration. There is no set time or volume between regenerations.

  • foxwood620 Mar 13, 2009

    Hi again. The only settings that I was able to check were as follows. Time of day, time of regeneration, salt dosage, backwash time, brine rinse time, hardness level. These are all set to the levels they were when the unit was installed. I have booked a service call for this Monday. And have unpluged the unit for now. If you have any ideas, I will try them first. Thanks.

    Hi, There is not a lock on the display, and I am able to change the settings. But as far as a setting for regen interval, this unit has an aqua-sensor which regenerates when needed. It may be the the sensor has gone a little screwy!

    Hi, You know, I have never asked if you see a little lock on your display. I am sorry I just assumed you would know if it was locked or not. If it is, you can only adjust the time of day without a service call. I should still display the interval though.

    Hi, The next status push after Hardness should be regen interval. It is in days on time clock models and gallons on metered models. Then you may have one or two settings after that which would be lock or unlock and enable or disable for the display. If you are not getting the regen display it is possible that there is a control board problem, but check your sensor connections to be sure. Let me know!

    Hi, Sorry been out of town for a few days, If you have a mark 100 it has those settings i am looking for. The auqa sensor is the device that tells the program head to go ahead with the regen cycle but you have to have something to set the interval. This is not optional or automatic. It is either a program setting or a mechanical timer.

    Hi, It must have been a coincidence that the time was the same. Never the less, it needs to be reprogrammed!
    There are defaults, but if you looked at the program what was the Regen Interval? If it shows a 1 it will regen everyday, if you have a time clock model. If you have a metered it works by gallons.

    Hi, After being unplugged for that period of time it has to be reprogrammed. Have you done this?

If this is an Aquasensor model. The probe is sending a signal to regenerate. It needs to be pulled and cleaned. You would need to call culligan for this repair.

Water in salt tank looked bad so i drained it should i put a couple of gallons of water in the salt tank after draining it to get circulation back again ?

The main problem in water softening units is that people continually use pool salt because it is cheaper. Most find eventually that it is not as it blocks the medium in the tank with sediment and rubbish. You may have to replace the medium in the system and restart the regeneration process Best policy is to use only kiln dried water softener salt It IS different.

My softener sucked all the brine out of the brine tank the last time it regenerated, now it will not fill back up?

It is not going into brine refill. There may be a restriction (debris) at the float assembly in brine tank. or the refill piston in valve may be bad.

Hard water, salt in in tank, what do i do

Make sure there is not a "Salt Bridge" in salt tank. Salt tank should always be at least 1/2 full of salt.
You may have just run out of soft water, run 2 manual regenerations in 24hr period. If no soft water still. The eductor assembly is plugged with iron or sediment and needs to be cleaned out. The eductor assembly is where the brine is drawn through to regenerate the resin.

That depends on what part of the cycle water is going into salt tank. If it is the last cycle (refill) it is normal until the proper water level is reached. If it is any other cycle then the brine piston or sealpack needs to be replaced.

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.

Mark 100 has a

I removed the control panel and saw that it had a series of dip switches. All these dip switches were all positioned to the same side, this is the way it was installed.

I reset it by flipping all dip switches to the opposite side, then unplugged it for 10 seconds and plugged it back in. The LED the. Displayed something other than the "CS" code. With it still powered, I reset the dip switches to original setting and unplugged again for 10 seconds. When I plugged it back in, I was able to reprogram. I'm sit sure if this is how a service tech would reset the control, but it worked for me and my mark 100 has been running fine since. Good Luck

Have a 30yr. old mark 20 culligan water softner which still works

You should not have to adjust the brine setting. Just the days per week. The salt dosage is dependent on the capacity. If you cut back on the days used you will still need to use the same amount of sodium to regenerate the softener.
