Question about GE Profile 26.6 cu. ft. Side-by-Side Refrigerator with Dispenser TFX27PRBWW

1 Answer

Water won't flow from GE Smart Water under-sink RO water filter

GXRM10GBL02 model - Changed all three filters. Reserve tank doesn't seen to fill. After many hours, flow only lasts about 20 seconds. I can hear the trickle of water into the drain from the RO filter.

Did I switch tubing lines when I replaced the Flow Control and screen in the 1/4" tubing from the RO cartridge?

Was I supposed to bleed off air somewhere?

    I also have the Ge GXRM10GBL02 model and this is the second one that I have owned. The first one had this same problem and now my second one does as well. It worked fine for a while then suddenly the reserve tank no longer fills. My tank is light and empty when I remove it but there is no pressure adjustment as far as I can tell on my tank. There is only the hose line in and a nut at the bottom of the tank. Not sure what to do aside from take it back again and use a different filter system.

Disconnect the water pressure tank making sure the end the line hooks up to is open. The tank should be relatively light, and if you shake it you should not hear any water. If you hear water in it, or it feels heavy, that means the bladder inside the tank has failed. Replace the tank with a new one, and set the pressure on the bicycle type valve at 8 PSI before you connect the tank up to the water line.

    Were you able to find the problem? I think you should have been able to with that info I gave you. Let me know how it turned out please. Hope you were able to do a Fix-Ya for your RO system.

    I have the same problem... my tank is light and has no water in it. It has around 10psi in the tank. Is there another issue?

6 stage ro system under counter style will not stop draining or producing ro water at all I removed unit changed 3 pre filters and a post polisher now I gotta problem How long will this unit run to fill...

If the RO is not shutting off and there is no water from tank there are several things to check.
1. The product water tank is probably low on air. The tank may be full but no water will come out. Put enough air in tank to force out all the water then reset air pre-charge to 7psi for 3 gallon tank.
2. The capillary tube / check valve of RO system is bad. This puts back pressure on membrane to help create water.
3. The Automatic shutoff is not working, causing the unit to run constantly.
I would have to know what model RO it is to narrow down the problem further.
Depending on the Membrane production 10, 25 gpd, etc. and the TDS of water it may take 24 hrs to fill the tank.

I changed all filters as per manual and cant get any water on the faucet. Pressure at storage tank is good at 7psi. But i got water after removing the RO filter. Any idea what would be the root cause?...

Check the capillary tube to make sure it is not plugged. This will restrict the flow from membrane. Also make sure the seal for membrane is not damaged. It takes several hours to refill the RO tank if it is empty.

I own an old Culligan RO system with a particulate filter, carbon filter, RO filter and post carbon filter all connected by tubes in an open environment. Replaced filters and tank is only 3-4 years old...

It is quite common to loose air pressure in the RO over time. At times the tank will be full of water but will not have enough air pressure to push water out. Take the tank of drain as much water as possible, for 3 gallon tank bring pressure in tank to 7psi, for 10 gallon tank pressure should be 10psi.

Just replaced particulate, activated carbon and polishing filters. Turned water supply back on, made sure polishing filter in properly as to flow. Allowed about three hours to fill tank. When I turned...

Is this an RO system or just filtration? If so, does the membrane need replacing and/or is the GPD capacity on the membrane compatible with the system?
Another thing to look your flow rate this low at a constant rate (perhaps taking 3 hours to accumulate 30 secs worth of water)? What are the micron ratings of the filters you are using? If they are too low or at the submicron level, this could massively reduce flow.
One more're only using one tank right? Because throwing a couple inline with each other with different pressures and capacities will also do this...

Culligan ac 30 reverse osmosis system - changed the filters, good flow for 3 days then began diminishing. Now nothing comes out of the faucet. Holding tank is empty.

I would pull out all the filters changed and check them. If a GAC filter is used as the post filter, before the RO tank, carbon fines can come out of the filter and can plug up the head on the RO system. Make sure the sediment pre-filter is not plugged and there is plenty of water supply. You may have lost pressure in the RO tank. A 3 gallon tank should have 7psi pressure when totally empty.

Our R-04 under sink water holding tank, for our culligan water filtration system got drained, and the pressure is now gone and it won't fill up on it's own. We had a leak, fixed it, but now need help...

The RO tank will still fill up even without any pressure it just won't push any water out. If the RO tank lost pressure and it is a sealed tank, it should be replaced. The bladder is bad.
A 3 gallon tank should have 7psi pre-charge pressure, 10 gallon 10psi. There must not be any water in tank to set the pre-charge pressure.
If the RO tank is not filling up then there is another problem.

No flow from EcoWater undersink filtration unit. Flow stopped so we changed two carbon filters and one sediment filter. Still almost no flow.

The water storage has probably lost its charge. A 3 gallon tank should have 7 psi pre-charge pressure. Tank has to be totally empty to set pre-charge. Turn water off to RO, pump air into tank to force all the water out at faucet, turn tank valve off and relieve pressure until 7psi charge.

There may be several causes for this. Here is a list of things to look for.
1. If an activated carbon filter was installed many times carbon fines will plug up the head of the RO housing. Pull the filters out and flush the whole assembly with NO filters in it.
2. The capillary tube (which puts back pressure on the membrane to create water) may be worn out and all the water will run to the drain. Replace capillary tube
3. The automatic shutoff may not be opening to allow for water flow.
4. Shut the water off at RO tank and take the line off from RO filters to see if any water is flowing from housings.
5. The RO tank may also need air. If the air charge is low in tank (7 psi for 3 gal tank) no water can be forced from the tank.
6. If the RO is fed by a piercing valve make sure their is water coming from it.
7. Depending on what type of RO it is their may be a flow restrictor in head of membrane housing that can get plugged also.
I hope these tips may help you,

Under sink tank on older water filter onlyy produces 2 qt at one time. it use produce 1 gal. we have lime iron promblem water 3 flter culligun system under sink water filer system over20 yr old filters...

I am assuming based on your description that the system you have is a reverse osmosis system. If this is true, you most likely need to recharge the air pressure in your RO storage tank. I have included step-by-step instructions below. If you find that your tank is not holding air or the tank will not empty completely, the bladder inside the tank may be broken and the tank will need to be replaced. I have included a link to our selection of RO tanks as well. To recharge the tank you will need a bicycle tire pump and a tire gauge that will be capable of reading below 10 psi. If you don’t have one that reads in single psi increments, then a meter that starts at 5 psi will work.

1) Close the cold water feed valve (if you can’t locate this on your system, you may be able to turn off the cold water to your sink)
2) With the RO tank valve on, locate the valve stem on the bottom or side of the tank. (this will look like the air stem on a bicycle or car tire)
3) Remove the stem cap.
4) Drain all water out of tank through open RO faucet into sink. (Continue to leave the RO
faucet open throughout the entire procedure)
5) If the current tank pressure doesn’t empty the tank, apply tire pump to valve stem
and pump a few times. Flow will increase and then gradually decrease as
pressure equalizes. Do not overcharge the bladder during this procedure.
6) Repeat step #4 and #5 until tank is completely empty. (Tank is empty when additional
pumping produces no more water)
7) At this point, adjust EMPTY tank to exactly 7psi. (Gauge reading midway between 5
& 10psi is sufficient)
8) Turn off RO faucet.
9) Replace cap on valve stem
10) Open cold water feed valve.
11) The water is useable immediately; however, tank will take a few hours to completely fill.
