WATER POOLS UP IN WASHER OVERNIGHT

The F21 error code indicates a long drain. Here are some tips that should help you resolve this problem:

Check your washer drain to make sure that it is draining properly.

Check the drain hose for kinks and clogs. Make sure that it is installed properly per the instructions in your owner's manual. An improperly installed drain hose can prevent the washer from draining properly.

Check for excessive suds in the washer tub. Excessive suds can prevent the washer from draining properly and will result in the F21 code. Make sure that you are using the proper amount of HE (High Efficiency) detergent to prevent excessive suds.

Place a shallow pan on the floor beside the washer and then pull the drain hose out and place the end of it in the shallow pan to see if the washer will gravity drain. If it does, then excessive suds or a drain pump problem could be causing this failure. If the water does not drain or drains extremely slowly, you could have a clog in the drain system of the washer. Follow these steps to check for a clog in the large item filter of the pump:

Unplug the washer.

Remove the bottom front service panel as shown in the first image below.

Since the washer door is likely still locked, you can manually unlock it by carefully reaching up along the front panel and pulling down on the manual release tab of the door lock assembly until it clicks. You can then open the washer door.

Remove any clothes and then use a wet/dry shop vac to drain any water out of the washer.

Arrange shallow pans and/or towel in front of the large item filter shown in the second image below to catch residual water when you remove this filter.

Remove the large item filter as shown below. It is likely that you will find a clog in this area that is preventing your washer from draining.

If you do not find any clog or restriction in the large item filter and none of the other issues discussed above apply to your situation, then you could have a failed drain pump. If the pump is damaged and will not pump out water then it will need to be replaced.

These tips should help you resolve the F21 error code issue in your washer. If you need more help, resubmit your question with additional details.

if you can get to the valve, disconnect the molex to the solenoid and if the water stops you have a control problem if it does not then the valve is bad

Finally the washer must be placed with a tilt- use a spirit level- so that all water will drain to the outlet port and thereby there is no residual water remaining.

First, unplug the washer and turn off the water. Get a small block of wood (about 6 inches high). Pull washer away from wall. Tilt back and place wood block under washer. This will allow you to access the 3 bolts on the bottom of the kick plate. Using a 1/4" socket, remove the bolts and set aside. Pull kick plate down. The drain pump is conveniently located in the front on the right hand side. Before proceeding, grab a garbage bag with no holes in it. You will use this to catch the water that will come out when you unscrew the filter. Place garbage bag under filter housing. Make sure to use one hand to keep the bag in contact with the filter housing (or ask your wife, kid, neighbor, etc to help with this) while unscrewing the filter in a counter clockwise direction. It will be difficult to turn due to the o-ring. Be patient. Turn it slowly. Water will start to come out as the filter is loosened. You may want to pause at this point and let the water drain. BEWARE! The will most likely have an offensive odor to it. Once all the water has drained, you can finish unscrewing filter and find your reward. I found a key, necklace, coins (mostly dimes), drill bit, nylons and lint. Be sure to clean the filter and housing with a bleach solution or vinegar solution before replacing filter. When replacing filter, be sure that it is tightened all the way down. If not properly tightened, the washer may leak when in use. Put kick plate back on and secure with the 3 bolts. Tilt back and remove wood block. Plug washer back in and turn on water. I would recommend running a clean cycle before using.

The IE fault code indicates that your washer is not filling properly with water This error code is displayed if the washer is not fully drained within 10 minutes. I will give you troubleshooting tips for both the fill problem and the drain problem.

To troubleshoot a drain problem, follow these steps:

• Follow the steps on page 17 of your owner's manual to clean the drain pump filter. If you do not have your owner's manual, you can access it on our Manage My Home website.
• Check your drain hose for kinks or clogs.
• Make sure that the drain hose is properly installed according to the installation instructions for your washer.

Here are some troubleshooting steps for the filling problem:

• Make sure that the water valves behind your washer are fully open.
• Check the filter screens on the inlet valves where your fill hoses connect to the back of the washer. If debris is clogging the screens, remove the screens and thoroughly clean them. Flush the inlet openings thoroughly with water to prevent debris from entering the washer and corrupting the inlet water valves.
• A drain installation problem can cause siphoning of washer fill water. Make sure that the drain hose is properly installed per the installation guidelines for your washer.

Dishwasher Problems - Water will not drain out

heatman101

If you experience a problem where the washer does not drain properly or the drain pump makes excessive noise, here's the information you need to check the drain pump:

Symptom: PUMP IS RUNNING, BUT NOT DRAINING PROPERLY.

1. Unplug the washer while servicing inside the unit.
2. Remove the lower kick panel under the door by removing the three 7mm screws under the bottom edge of the panel. HINT: Use a couple of blocks of wood to prop up the front feet of the washer to gain better access to the screws. Once the screws are removed the panel should drop down, and then pull off. If the panel becomes stuck, a slight tap on either side will dislodge it.
3. Locate the drain pump. It will be located directly under the wash tub (it is the only pump this washer has).
4. There is an access removal cover on the pump that can be removed to clean out the trap. BEFORE doing this, it is strongly recommended that you remove all residual water from the wash tub & drain line or you will have about a gallon or so inside your washer and on the floor to clean up.
5. Here's a helpful way of quickly removing the residual water. If you own a wet/dry shop vac, remove the drain hose from the standpipe at the wall and pull a vacuum with the shop vac. This will empty the wash tub, pump and drain lines. If you don't own a shop vac, grab a bunch of old towels and open the access on the pump slowly so that it comes out at a trickle. Allow the towels to soak up the majority of the water. Close the access and stop the water if you need to get additional towels.
6. Open the pump access and remove once you have all the water drained. Check the drain pump for foreign objects and debris. Check the pump impeller and make sure there's nothing caught in it. Items as small as toothpicks or cotton swabs have been known to stop this pump from working.
7. Clean out the pump thoroughly and reinstall the access cover. Make sure the cover is snug, but do not over tighten.
8. Place the drain hose back in the standpipe (IMPORTANT - DO NOT FORGET!).
9. With the bottom panel still off, plug the washer back in and select the following on the operator console - DRAIN SPIN, NO SPIN, and then press any button under OPTIONS 4 times (it must be the same button). "C00" will show on the console display as the washer begins diagnostics mode.
10. Check the drain pump for leaks as the washer fills. The pump is gravity filled and will hold water even it is not pumping. Allow washer to run through diagnostics until it begins the wash tub tumble cycle.
11. At this point, you can stop the diagnostics procedure by pressing PAUSE/CANCEL 2 times. The drain pump energizes and the washer will begin to drain.
12. If the drain pump works normal and there are no leaks detected, reinstall the bottom panel and tighten screws.


NOTE: It is normal to have residual water left inside the wash tub under the wash basket. This is why it is important to leave the door ajar when not in use so this water does not become sour.

Try cleaning the drain plug. I did this in about 5 minutes and was amazed at how much debris was clogging up the drain. Mine was accessible by removing two screws at the bottom of washer and removing panel. Drain plug was right there and easy to unscrew. Be sure to have a cookie sheet or other pan to catch the water that will flow out. Once that drain is clear, thumping should stop because water can flow down the drain easily.

Q - My washer seems to keep filling  with water, the water keeps coming in the washer and going out the drain without the washermotor running.
A - This often is a drain hose that is too low or a drain hose that has been pushed too far down inside the stand pipe....the water is actually siphoning out of the washer. Do not "seal" the drain hose to the house plumbing pipe, this will also allow the water to be siphoned out.
