Why is my Kenmore stackable wash machine and Dryer making random dripping noises when not in use?

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.

Likely the main drum bearing in the back. I have seen these go bad, and loud squeaky noise tells you. You can get a new main bearing and replace. It is in the center of the back of the drum, accessee through back panel of dryer usually.

It is possible that the belt has come off or the lid latch is no functioning.

First unplug the machine then remove the two screws from the front lower edge of the washer.

The front panel will lift up towards you at a 45 degree angle. The latches will release than the entire front panel can be place out of the way.

The lid latch can be seen on the underside of the top panel to the right, check that the wires are not loose.

You will see a large motor mounted upright near the base this should have the belt around the pulley to the bottom of the tub assembly. Check for obvious damage

Outside of this you will need a repairman for help.

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 front panel comes off and you will be able to trace the water source. These combo units spin immediatly and if the drain is slow the water will spin up over the edge of the tub during drain.
