Washer agitates so vigorously water sloshes out of the overflow tube on large,extra large and super cycles. Tub slams back an forth on agitate cycle is this normal?

My parent's Hotpoint did the same thing!! The brake on the bottom of the tub is not engaging! It needs replaced!!

Sounds like a lid switch

the purpose of that tube so it anywater that comes out of it goes through it and directs the water down the back and away from the motor. Now the bigger issue is why is water coming through that tube.What i suspect the reason of that is that the transmission is defective and the break is that internal to the transmission is slipping so the inner tub turns during the wash cycle force water up the side of the tub into that tube.during the agitate cycle the tub is not suppose to move at all and stay locked into place,but instead its moving where the water is forced up by centrifical force too and out the top of the tub cover,if it leaks with only a small water load it will leak worse with a large water load. if this is what is happening and the tub is rotating on agaitate cycle teh fix for that is to replace transmission which in most cases cost as much as replacing the washer would be

sorry to say you have a very expensive to repair problem ):
the transmission has a brake built into which is suppose to hold the tub in place during the agitation cycle and then release on the spin cycle to spin. the brake isnt engaging and the only fix is to replace the transmisson which is very expensive.
it may work for awhile then as it gets worse and the tub moves more during the wash cycle water will slosch out of it all over the floor,sorry to break the bad new

The water-level switch regulates your washer's fill volume. This switch is usually a diaphragm device with a small, clear tube attached between the switch and the bottom of the washer's outer tub. As the water level in the tub increases, the pressure on the air in the tube increases. When the pressure reaches a certain level, it activates the switch, shuts off the water, and signals the timer to begin the agitate cycle. If the switch is defective, it may prematurely signal the water to shut off. If so, you probably need to replace the water-level switch.

I have a 2005 model GE washer that would overfill only on SUPER size load. After looking around on the web, then inside the machine, I checked the tube from the tub to the switch, no problem there. Then I found an adjustment screw on the load size selector / pressure switch (all one piece). I moved it one turn clockwise, then ran a test cycle. I got lucky on the first try... no more overflow, the water comes up just above the top holes in the tub. I hope this will help others.

Water-inlet valve A defect in the water-inlet valve may mean that it's no longer able to shut off completely when the electricity has been turned off to it. If this occurs, the valve may leak and drip water into the clothes tub. In time, the water may accumulate substantially. If this happens, you need to replace the valve.

Water-level switch A defect--or an obstruction--in the water-level switch may mean that it can't tell the water to shut off. So the machine overflows. This switch senses the water level in the clothes tub. It's usually a diaphragm device with a small, clear tube attached between the switch and the bottom of the washer's outer tub. As the water level in the tub increases, the pressure on the air in the tube increases. When the pressure reaches a certain level, it activates the switch, shuts off the water, and signals the timer to begin the agitate cycle. You can either clear any obstruction in the tube or replace the water-level switch.

ck under agitator pull dispenser out remove large wing nut dowm center of agitator pull up ..nothing there remove rubber pluggs each side of top remove phillip screws lift top pull tub ring off at tabs along edge and remove.. basket lifts out ck under it

Hi,
I found this answer on Repairclinic.com. Hope it helps...

The inside tub moves on the spin stage only and cause the water, by a centrifugal force, to be forced out of the clothes. During the wash cycle,the tub is stationary and the agitator moves forth and back. If you would like to remove the agitator - Remove the inner agitator cap (inside the top of the agitator) and then open the screw (be aware not to lose parts !) Good luck !
