Question about Whirlpool Refrigerators

2 Answers

I have a new Whirlpool refrigerator (model ED5FVGXWS06) with an icemaker and water dispenser. It currently has a copper tubing water line with compression fittings which supplies the icemaker and water dispenser. The copper tubing is then connected to a plastic line (via compression fittings) which hooks up to a reverse osmosis water filter. While it works fine, I am having a problem moving the refrigerator back against the wall because the copper tubing line keeps crimping and won't coil back the way it is supposed to. What I would like to do is to replace the copper line with the more flexible "stainless steel" braided hose which I see is available in home supply stores. However, the Whirlpool instruction guide which came with the refrigerator indicates that copper tubing (1/4 inch) should be used to supply the icemaker/water dispenser. On the other hand, the water supply to the refrigerator is filtered water which comes from my "reverse osmosis" water filter, and I have read that filtered water from a "reverse osmosis" filter can corrode copper tubing and cause problems. Therefore, my questions are as follow: 1. Even though the Whirlpool instruction guide states to use copper tubing, can I instead use stainless steel braided 1/4 inch hose for the water supply to the icemaker/water dispenser? 2. Can I use teflon tape to help seal compression fittings, and do I need to do this? 3. If I am using filtered water from a reverse osmosis filter, should I even be using copper tubing? 4. The way the refrigerator hose outlet is positioned on the back of the refrigerator, it is probably necessary for me to install a brass elbow in order to properly position the supply line. Can I use any of the types of brass "compression fitting" elbows which are sold in home supply stores to do this? 5. All things considered, what is the best kind of tubing or hose to connect the refrigerator with the water supply? Thank you for your time.

    Thank you for the information. What confused me is that in the Whirlpool instruction manual, they briefly discuss reverse osmosis water supplies, in terms of a possible loss of pressure, but they do NOT advise against using copper tubing which they recommend. I cannot understand why they did not mention the problem of reverse osmosis filters and copper tubing.

    While I appreciate the other expert's response, it does not appear that he/she is a Whirlpool expert. Can I also receive a response from a Whirlpool expert?

    Thank you.

    Thank you for your help.

    Thank you for your help. I just didn't know whether you were a Whirlpool technician, and what I was concerned about was Whirlpool's insistence upon the use of a copper line. However, I do appreciate your prompt response.

  • matt4976 Mar 13, 2011

    Ok, I'll gladly do that. Only thing is that I also accepted his, as the correct answer. Can I do both? If so, just tell me how to do it and, as I said, I will be happy to oblige.

I despise the copper water lines on refrigerators for exactly the reason you have mentioned. This is why my customers will not pull out the refrigerator to clean behind it and to clean the compressor area which in turn causes non cooling issues.
I have many times installed just the plastic water line seen on many part distributor
You now will be able to move your refrigerator in and out without the worry of crimping the line. If you can find a long enough Stainless braided line....even better.
Just ignore the Whirlpool instruction guide on the matter.
It should not be necessary to use teflon tape on compression fittings. The compression fitting is made to seal without the tape.
Using a reverse osmosis should not harm the copper line. If you have hard water this would have a tendency to harm the copper more than the osmosis filtering.
You can use a brass fitting but with the plastic line you would not need one.

Here is the link that will show you the line you can use. The copper line is not for the water but for the compressor.

if you have any other questions and or concerns please post.

    I also have a reverse osmosis at my lake house and was the maintenance manager @ coca-cola where we produced the dasani water....reverse osmosis filtering. I have never seen any adverse conditions because of this filtering procedure.

The storage tank, tubing, and dispensing faucet should be made of plastic, stainless steel, or other nontoxic materials. The low pH and mineral content of RO-treated water may corrode copper pipes and allow lead to leach into the drinking water from brass components.

Since RO pure water is very aggressive, if ran through a copper pipe it will pick up a copper taste. The tubing after a reverse osmosis unit should therefore be non-metallic. RO units will pass all the CO2 that is found in the feedwater.
The best solution for you is to use all plastic tubing and compression fittings, you won't need teflon tape with compression fittings. The plastic tubing is also the most flexible and forgiving, just don't pinch the lines.
I hope this answers your question and a vote for the solution would be greatly appreciated. Thanks for using fix Ya.

    Whirlpool is the manufacture for most refridgerators in the country. The answer I gave was the answer to your question, They suggest copper tubing on all makes and models, but if you use Ro water it will taste like copper and will deteriate your lines , that is the bottom line! If your water pressure is good then don't worry.

    I just don't have the whirlpool badge on my Fixya page, but I appreciate your reply and concerns. If a whirlpool Expert give you the same answer I would appreciate if you accept mine if you deem it correct and once again thanks. They are only concerned with water pressure so that the ice maker and such work like they should and like I said if pressure isn't a probl;em then don't worry.

  • Dcramer531

    No can only accept one, looks like I lost out here. But life goes on. I am not sure if the fixya team can help with that or not, I don't get to see that end of the business. was his answer the same as mine?

Which water line or lines do I connect to refrigerator, model # ED22RFXW01, man. 08/99

It's advisable to go with flexible plastic tube with sweet water supply. Please follow the instrction as per video attached.

Even if your refrigerator comes withan automatic icemaker, you will need to connect it to a water supply for it tomake ice. While this is not a particularly difficult job it requires someknowledge of plumbing and the use of tools. ThingsYou'll Need:
  • Compression Nuts
  • Knife Or Scissors
  • T-valves
  • 1/4-inch Copper Or Plastic Tubes
  • Drill Bits
  • Variable-speed Drills
  • Drill Bits
Read theinstruction manual that came with your refrigerator. Specific instructions forhooking up the icemaker may be included. Locate thepipe nearest the icemaker that carries cold water. Most often, this is the coldwater pipe that connects to the kitchen sink. Install at-valve in the main cold water line - not on the 3/8-inch faucet tubes - sothat there are two outlets: one to the sink and one to the icemaker supplyline. Turn offthe water. Put asleeve and compression nut over the line that will supply the icemaker in orderto tightly connect it to the water line. Turn thewater back on, and, holding the end of the tubing in the sink or over a bucket,flush the line to remove any debris. Turn the water off again. Snake theline from the water source to the icemaker connection, drilling holes in thebacks of cabinets if you have to in order to push the line through. Find theicemaker inlet from the refrigerator and attach the other end of the line usinganother compression nut. Turn thewater back on. Throw awaythe first few containers of ice to be sure the line is completely clean beforeyou use the ice.

Replace water inlet valve for ice dispenser with new. When icemaker cycles it dispenses through the water dispenser instead of tube going to ice maker. I have switch lines around but can only get water...

The ice maker is what tells the water control valve to open so it may be correct now and the thermostat in ice maker may be defective. Part 27 or 627985 down below where it says Whirlpool Ice Maker Parts Breakdown and in that photo is the ice maker thermostat. If your ice maker has been used for many years the complete ice maker may be better to replace. Ice maker Model=> 4317943

Whirlpool indoor ice maker not making ice

Could not locate your model number. However, Check fill tube for icemaker inside the freezer. Iced solid? replace water valve. No ice in fill tube? Get correct model number and resubmit your request.

Replace selenoid and water is still not going to ice maker

Did you pour about 2/3 cup of water into the icemaker and did it dump ? If you did pour water into the icemaker , and it did not dump the cubes , then the icemaker is bad . If it did dump , so you replaced the water valve , then the fill tube directly at the icemaker is frozen with ice . It will need to be removed ( fill tube at icemaker ) and the ice cleared out by hot water . On some models , behind the refrig , 2 screws hold the fill tube in place . Remove the tube , and clear the ice . When reinstalling , have someone guide it from inside the freezer , to where it mounts on the icemaker fill cup .

Water dispenser problem

Did the man who installed it use plastic hose or copper pie? PLastic pipe can get crimpled (closed) and starve the water supply.
Simply move the refrigerator far enough away from the wall and see if the tubing is crimped. If it is copper and it is crimped- you should call the installer back to repair the copper pie. Once copper pipe is crimped- it is unusable and must be refitted with a coupling or union or some other proper repair.

Maybe this is all that is wrong.......
Hope this helpes!!!

Icemaker is not making ice

check the fill tube on the ice maker to see if its frozen upo. if it is you are going to need a new solinoid valve due to it leaking thru the valve and freezing up.

I had a Whirlpool Model GD5SHAXNS in which the icemaker quit working about the same time (3 years old). I had water out the dispenser, I found that it was the icemaker itself failed not calling for water to fill it. I replaced it with a icemaker on-line for about $100 and problem fixed. I have been told his is a common problem with the icemaker in this model ref.

Whirlpool icemaker

Try using an hairdryer or defrosting the unit completely , this often get rid of blockage caused by frozen lines fixing the problem.

The water lines can also be unblocked from dirt using a thin flexible shaft. This after defrosting.

If all that does not fix the problem, then you may need to replace the water valve, the icemaker solenoid, or the whole icemaker assembly.

My new Whirlpool Refrigerator the water and ice still stink

Change the supply line to the plastic tube line or copper. Do not use a braided plastic or metal braided line these will make the water taste bad. Changed mine to the plastic line and cured mine, no filters needed.
