Filter Replacement and Sanitizing Procedure
Use the following procedure and the reference in Fig. 3 when servicing the Good Water
NOTICE: Cleanliness is essential in the filter replacement procedure. Be sure to wash your
hands thoroughly before handling filters. The use of protective gloves is strongly recommended.
Pre-flushed activated carbon cartridge and polishing filter cartridge
Particle filter
Household (5.25%) bleach - hydrogen peroxide is not recommended
Clean 1-gallon plastic container with cap
100-ml graduated cylinder
Plastic pan to hold manifold assembly
Tubing connector, 3/8” tube x 3/8” tube
Flat-blade and #2 Phillips screwdrivers
Paper towels
Disposable plastic gloves (like those used in the food service industry)
1. Locate the system’s supply valve and turn off the system’s water supply.
2. Using the graduated cylinder, add 5 ml (about 1 teaspoon) of bleach to the 1-
gallon container. Open the dispenser faucet and fill with one gallon of product
water. If there is not enough RO water, fill the container the rest of the way with
soft water. Cap the container and shake to mix.
NOTICE: If any RO water remains after filling the container, you may want to fill a
pitcher with the drinking water as it will take several hours for the system to refill after
servicing. In any case, leave the faucet open until the storage tank is empty and then, close
the faucet.
3. Remove the polishing filter (Fig. 4) and discard. Connect the tubing ends together
with the tubing connector.
4. Lift the filter assembly from the mounting bracket and place it in the plastic pan to
catch any dripping water.
5. Using the flat-blade screwdriver, pull the u-clips from all three housings. Insert the
u-clip into the two square holes at the bottom rear of the manifold and push up to
release the filter housings. Remove the housings with a downward twisting pull.
6. Remove the particle filter cartridge and the activated carbon cartridge and discard.
If the RO membrane filter will be reused, clean the outside with a wet paper towel
and place the membrane filter in a clean, unused plastic bag.
7. Wet some paper towels with the diluted bleach solution. Clean the inside of the
housings and the underside of the manifold with the paper towels.

1. Add 15 ml (about one tablespoon) of bleach to the particle filter housing (#1,
Fig. 3). Replace all three housings on the manifold and insert the u-clips.
2. Turn on the supply valve and fill the storage tank with 1 to 2 gallons of water.
NOTICE: The weight of the storage tank will increase by 8 to 16 pounds. Turn off
the water supply valve.
3. Wait ten minutes before opening the faucet and draining the storage tank. Do not
rinse any remaining solution from the tank.
NOTICE: During this time, proceed to the “Sanitizing the Manifold Assembly” section.
Wait to do step 4 until indicated.
4. Remove the temporary tubing connector and replace it with a new polishing filter.
Make sure the flow arrow on the polishing filter points to the faucet (Fig. 4).
1. Using the flat-blade screwdriver, pull the u-clips from all three housings. Insert the
u-clip into the two square holes at the bottom rear of the manifold and push up to
release the filter housings. Remove the housings with a downward twisting pull.
Discard any solution remaining in the housings.
2. Open the particle filter cartridge bag half way, being careful not to touch the filter
element. Lubricate the particle filter cartridge o-rings with water and insert the
cartridge into position #1 in the manifold.
3. Fill housing #1 about 2/3 full of the diluted bleach solution from the 1-gallon
container. Assemble the housing to the manifold and replace the u-clip.
4. Repeat steps 2 and 3 for housing #2 (activated carbon cartridge) and housing #3
(RO membrane filter).
NOTICE: For RO membrane filters that have a single open-end, pour diluted bleach
solution into the center tube.
CAUTION: The solution should remain in contact with the RO membrane filter
for at least five (5) but no longer than ten (10) minutes. Longer contact time will
shorten the life of the membrane.
NOTICE: While waiting for the filters to be sanitized, complete step 4 of the “Sanitizing
the Storage Tank and Faucet” section. Then complete step 5 below.
5. Using the #2 Phillips screwdriver, loosen the capillary assembly retaining screws,
then twist and remove the assembly. Inspect the tubing for plugging and kinks and
replace the tubing as needed. Reinstall the capillary assembly, but leave the screws
¼-turn loose.

Or go to link below to get the manual starting on page 8 tells you how to service the system.

Fills then stops even with door open

Aha, I see.

Well, there are only 2 likely issues here. Either the inlet valve is faulty (Jammed open), or the controller module is faulty. However, If you haven't already, before you do anything else, unplug the machine from the mains for 30 minutes. There is a small possibility that this will reset a faulty program or setting and all will be OK. Unlikely, but worth a 30 minute wait. Expect this to fail, but it's worth a shot. Presuming it fails move on to the instructions below:

To test the inlet valve, you are may have to pull a wire off one of the terminals and see if that causes it to shut down. In case you're not sure the hose on the back of the dishwasher screws onto a fitting and that fitting is part of the inlet valve assembly, so you need to get to the back of the fitting so you can see the valve (This should be pretty easy and a case of just removing a few cover screws or, more lokely the top of the discwasher).

I'm presuming that you currently have the water turned off, so do the following.

TEST 1 is simply turn on the water with the machine unplugged. If water starts entering the machine when it's unplugged, then the valve is clearly jammed open and needs replacing (You just MAY manage to find some debris jamming it open and clean them out, but its a little unlikely and you will probably need to replace the nvalve. It's a pretty easy job as you will be able to see once you have it explosed with the top off the machine)

Where test 1 has shown that with power off, no water enters the machine, let's test to confirm that the controller is opening the valve at the wrong time:
Ensure that the water is now turned ON but that the machine is
Gain access to the valve as discussed
remove one of the 2 wires that run to the valve
Plug the machine back into the wall. Does water start to run through the valve? (This should not be possibl if it passed test 1)
Turn the machine on at the front panel. Does Water start to run through the valve? (This should ALSO be impossible if it passed test 1)
Replace the wire on the valve that you removed
Power on at the mains agian and repeat the above tests. You should expect that water will start to run into the machine again, demonstrating that the controller board is faulty. There is a tiny chance that the unplug/power off and disconnect procedure may have reset a problematic valve or controller module, in which case, count yourself very lucky. It's more likely if you have reached this stage and you still have water flooding in taht you have just proved you need a new controller module.

The water in our culligan water cooler keeps turning into ice and will not come out of the unit. How do we prevent it from freezing?

There is a thermostat that is to shut off the cooler. It has gone bad and will need to be replaced. Often the Culligan contract includes the cooler maintenance and repair...check with them, they should fix it for you.

How do you go about "descaleing" the coffee maker? The water does not flow through the coffee capsule very well.

I know that most grocery stores sell a "cleaner" or two next to their coffee filters/coffee makers/kitchen appliances section. These are usually heavily acidic, and will do a great job of cleaining your coffee maker. I've always been wary of acid in my coffee though, so I just use white vinegar. It'll do a decent job of cleaning out the coffee maker. Run a 1:1 mix of water and vinegar through your coffee maker, drain it, then run water through at least twice.

Scaleing/deposits building up in a coffee maker are signs of imperfections in the water. All tap water has it, but if you don't want to worry about it, use bottled or filtred water in your coffee pot. Plus, your coffee will taste better!

We have owned a Britta for over 30 years. Recently when changing filters the water has a greenish color. Hoe do we get rid of it? Is it safe to drink?

If you mean a water softner on tap, then you will need to sanitize it with Sodium Metabisulphate or similar. Fill the unit, not the filter, with a solution and leave for 10 minutes then flush it slowly through the pipes, Baby sterilization liquid will work. You have to remove the algae.
It probably is safe to drink but I wouldn't!
Hope that helps.

Remove the grease filters. This will expose the two screws that hold the lamps in. Turn the screws anti clockwise until the lamps drop a little. Twist the lamps gently anticlockwise to release them from the fittings. My instruction manual says reverse the procedure to insert new lamps. Haha. Good luck and be careful.
I had a lot of trouble getting the lamps back in. So much so that I have somehow damaged the fittings or wiring and now have to have a repairman out.... looking at $150 plus just because a light blew!

If you were to log on to the manufacturer's web site, I think you will be pleasantly surprised as usually one is able to download, by model number, Customer Instruction Manuals, list of Dealers, for spare parts and service, Driver downloads and Installation Instructions as required.

This is the best way of ensuring up to date drivers for your system and they are free of charge!

I hope this helps.

Is there a service manual available for Kenmore Deluxe Water Purifier Model No. 34481?

Is this the right unit: ? The parts list and owner's manual are available but the the parts blow up doesn't show where the parts fit. The link to the parts list is on the right hand side of the page. No additional service manual appears to be available from Sears/Kenmore.

I hope this helps.

LG RefrigeratorModel LFX25960ST - icemaker has been replaced once

Most ice maker heads cost less than $49 to replace if you get it at a wholesaler. The water quality going to it will effect how long it will last, Reverse Osmosis treated is the best, filters will help some but are not a cure. Your budget is the determining factor in this equation.
