    i traced it all the way up to the door. There is a little valve at the bottom of the door. the water reaches that, then after the valve it dosn't flow. I discoinnected the valve and it works fine. the air lock is in the door. i tried to figure out how to open the door up but is all sealed. any other suggestions?

    I disconnected it and then pushed the leverand water shoots through it fine. It's just when i reconnect it to the end that goes up through the door to the spigget. the valve i was talking about is (i think) just a rubber coupler. if you push in on the white rings it disconnects from the little tubing. I believe the problem lies from that coupler to the spigget . so it is something inside the door I can't get to. Any suggestions? Thanks for your help.

Yes this is air lock. You will need to bleed the system. Loosen the nut that is running to the machine not to the valve and let the water squirt out. If that doesnt do it then you will need to remove it all the way and allow water to run trough it for 15 seconds then you will be ok. Other problem is that you could have it on upside down

    The valve that you are talking about is a pressure valve. Meaning that the water has to have enough pressure to get through it. If the pressure is not high enough, then it will just stop there and nothing will work. That valve could be bad and need to be replaced also

    I am very sorry for wasting your time with the. To get to the spicket and inside the door. You will need to take the ice and water spicket apart.
    I hope this website helps you see how to remove the cover to get inside

Water in basement in flood that covered the lower element. When power was turned back on, the green light on the top of the heater was blinking twice. When I hit the reset button, it is now blinking...

Yes sensor should be replaced along with lower element.

1) Manufacturer's say that flooded water heater should be replaced: Call homeowner's insurance company.

2) Brand of water heater is not known, but it could be the American or Craftmaster or Whirlpool energy-smart electric with control box.

3) With energy-smart:
1 flash is start-up failure, and 3 flashes is sensor failure.
The moisture probably shorted element and/or lower sensor.

4) The moisture inside tank will take long time to dry out, especially since the foam insulation is wrapped tight. To dry out element and sensor, you have to remove cover and insulation over element, but if you leave insulation off and run water heater, then the sensor is exposed to cool outside air and will not read temperature inside tank.
Plus a wet water heater is electric shock hazard.

Premier Plus Model#MHE62-30H-045DV Ser#45T421608 I just purchased this hot water heater.I had it professionally installed by a plumber.We had hot water before I went to bed but when I woke in the morning...

sounds like you have a power problem. or worst than that a leak . So lets look at the leak first. Turn off the water supply at the water heater on top. This valve should be on the cold side of the heater on top.

Turn it off, check and see if you have pressure in the house by turning on a faucet. It should run for a second then stop. That is good if it does. Leave the valve off on the heater and check that your breaker is on. Reset the breaker by turning it on and off.

Wait about 2 hours turn the heater back on and check to see how hot the water is hot then you might have a leak in the building. If there is not or little hot water. Check the wires where it connects to the water heater. You might only have one wire that is connected right.

The best thing to do is to get a amo meter and check to see if you have 220 if you dont have 220 you will not warm up the water the way it should.

Thanks Richard

GE Smart Water under sink dual water filters replaced. Very little water pressure. I have reinstalled them, no improvement. I have been replacing these filters for 5 years and have not encounerted this...

Hi jbboggeri,

Welcome to fixya!

I would go ahead and open the new set and install them. If you get pressure, you know the others were bad and can send them back for a refund.
If there is no change, you can always put them away and use them again later.

Please reply back and let me know how it went. Thanks,

My 40 gallon whirlpool electric water heater stopped working today

The thermostat (either the upper or lower if it has two thermostats) has an integral circuit breaker that trips if a problem occurs. First try resetting the breaker. Look for a red button in the middle of the thermostat (which will most likely be behind a metal panel. BE SURE to shut of the breaker in the electrical panel that serves the water heater.

The water heater should start to heat up if the thermostat breaker doesn't trip right away. However, if the breaker on the thermostat trips again at any time, there is most likely a short in the thermostat and it needs to be replaced.

They two thermostats are not identical. The upper unit typically has three wire connections while the lower unit only has two.
If you find that one of the units must be replaced, ensure that you get the proper replacement. Then, you should mark the wires and their connection points and then disconnect them. The thermostat can then be slid out of the clasp that holds it to the tank. Slide the replacement in and reconnect the wires and ensure that they are tight.

You should complete your water heater thermostat replacement by turning the power to the unit back on. Observe the proper operation of the water heater and ensure that the thermostat is set at the desired temperature. (The temperature should normally be set at 120 degrees to save energy and avoid burns.)

Only you know your level of ability. Water heaters are high voltage and draw a high amp load. If you feel you cannot safely perform this work, do not attempt it. Call a plumber instead.

Hope this helps.

I have a GE MWF water filter that is dripping water into the refrigerator. Fridge is about 8 yrs old and have changed many of the MWF water filters. 1st time with this problem.

Many times fines from these filters become dislodged and plug up the filter housing. If you have the bypass plug for the filter, install it and run a couple gallons of water through fridge to flush the system completely. The install the filter again. Make sure none of the water lines feeding fridge are pinched or kinked and valve is on all the way.

I am on a well system (submersible pump) and low pressure issues happened this week. Checked the pressure on Smart Water system and it was 45psi. I replaced the paper filter with a carbon filter cleaned...

This could be caused by several different issues. A faulty switch on the well, bad well tank, bad check valve. If you have a water softener, bypass it to see if pressure loss is through it. That carbon filter will cause even more pressure loss. Turn a cold water faucet on, let the well cycle several times and observe the cut-in and cut-out pressure. Typical well pressure pressure will be 40-60psi.

GE smartwater filter (model GXRLQR) stopped!

These replacement filters (GXRLQR) are FLAWED straight out of the factory. The problem is in the 2 little "teeth" nubs that stick up near the center circle of the filter. When the filter is twisted and inserted, these teeth push up on a tiny black spring loaded valve in the body of the filter, alowing water to pass through up and out the spigot. The flaw is that the "nubs" are too short and do not push open the spring valve far enough, reducing flow to a semi-trickle, even with a brand new filter. GE seems to think this is not a problem.

Solution=stick a $0.25 garden hose rubber washer in the top of the filter and screw it in. You may have to try a few times to get it to work and seat properly. When it works, you'll immediately get a nice super flow of water. Better than upgrading to a $200 filter system recommended by GE...

I was changing my filter in the ge filtration system, and it says to turn off the water and press the red button. Then it says to unscrew the filter take the old one out and clean the filtrstion system...

The red button is a pressure relieve valve. If the system is leaking from the valve, try pushing the valve up from the underside of the cap where the valve is located. If this does not work the housing needs to be replaced. You do not have to replace this with a name brand like GE. All you need to do is make sure the housing that you are purchasing is the same size.
