We have a stackable maytag washer dryer and the fuse on the washing machine keeps blowing what could be the problem

SOURCE: water keeps draining

You may be experiencing what is known as "siphoning".  If you have your drain hose shoved too far down in the drain standpipe, or if you have the top of the standpipe opening sealed off, sometimes it creates a vacuum and will cause the washer to drain constantly drain.  You need an air gap in order to prevent this.  Double check your drain hoses for the following:

1. Make sure the hose is only placed in the standpipe about 3 to 4 inches.  If it is sitting so far down in the pipe that it is resting in the trap where all the water is it will siphon.

2. Check the opening around the top of the standpipe where the hose rests.  Makes sure there is still an air gap around the hose.  That is, make sure the hose isn't seated so tight that it seals off the standpipe completely.  This will cause siphoning.

3. Make sure you haven't placed anything around the standpipe opening.  Many people will wrap old towels or wash cloths around the opening in order to prevent overflows and odors coming back up through the pipe.  In doing so, they often inadvertently seal off the standpipe and cause a siphoning problem.

Last of all, the standpipe should be about 36 inches from the floor.  If your drain line is sitting too low it can also cause siphoning issues.

I know I'm keying in on this drain line issue quite a bit here.  There are some other things that can cause water levels in a washer to drop, but you mentioned nothing about any leaks and this is the most common problem.  You will know for sure if you pull the drain hose out of the standpipe and suddenly hear a sucking noise.  This is air being reintroduced through the drain line.  I hope you find this information helpful.

There is a micro switch next to the fuse. It is shorted out. Replace the micro switch and solve your problem.

SOURCE: mle2000ayw Stackable washer/dryer not washing, spinning

If the door lock light is on then is might be the "door lock enable spin switch" the plunger at the opposite end from the wax motor is not fully depressing the switch. In the stackable it is just behing the door lock. Remove the two middle covers (2 white phillips screws and one hex head screw on the middle of lower cover by the wires)to test place a few layers of masking tape on the end of the plunger and cycle the machine. Might also be a weak Wax motor (dark brown in color) to be safe replace both for about $12 each. Fix in 10 - 15 min.

The Service Manual for reference. Sears Parts Direct for reference.
I have tried to work with a few folks on this issue never received feed back to resolution see this post. I feel the issue is caused by one of three possible issues.

A stuck key issue/defective Spin Cycle key making constant contact forcing the Key/LED to cycle thru the Spin Cycle settings. Under normal conditions if you press and hold the Spin Select key it will cycle thru the settings, yours has a mind of its own (defective issue).

A false signal from the Control Board for the Spin Cycle.

A corrosion path issue at the Membrane Pad ribbon cable socket connection between pins 5 and 4. See page 20 of the SM button functionality “Spin” key.

Try to verify that the spin cycle membrane key is not stuck/defective signaling the Control Board to cycle thru the spin settings. I have not experienced this issue but let’s try the Membrane Pad Test to get a start point. See the Service Manual page 15, I have modified the process to make it a bit more understandable at least for me. Make sure the two digit display is not On or Lite.
Press the off button first so there is nothing displayed in the Two Digit display of your FAV6800AW.

Now Enter / Exit Service Mode

To enter Service Mode press the Enviro Plus and Spin Only keys for three seconds or until the control beeps. While in Service Mode, pressing the Presoak key will start a membrane switch check that verifies switch operation.

All the LEDs (except Presoak ) can be toggled or slewed by pressing the key associated with the LED or set of LEDs. Do not press the Presoak again during this test.

Press each key once and only once including the Signal Key the on side and the off side, also the UP and Down Arrow key of the LED display. All keys (including the OFF button) must be pressed within 5 minutes for this test to pass. “PA” will be displayed for five (5) seconds once all keys have been pressed and the test is completed (more like PA will be displayed for only a few seconds on my FAV6800AW). Following 10 seconds of inactivity at any point, this test will exit without any display. Let us know the results.
