for assistance and to possibly avoid a service call.  

Feet may not be in contact  

with the floor and locked.

Front and rear feet must be in firm contact with floor, and washer must 

be level to operate properly. Jam nuts must be tight against the bottom 

of the cabinet.

Check floor for flexing or sagging. If flooring is uneven, a 3/4" (19 mm) 

piece of plywood under your washer will reduce sound.

See “Level the Washer” in “Installation Instructions”.

Load could be unbalanced.

Load garments in loose heaps evenly around the washplate. Do not load 

garments directly over the center of the washplate. Adding wet items to 

washer or adding more water to basket could unbalance washer.

Wash smaller loads to reduce imbalance.

Use Bulky Items cycle for oversized, non-absorbent items such  

as comforters or poly-filled jackets.

See “Cycle Guide” and “Using Your Washer” in this “Use and Care 

Guide”.

Empty pockets before washing. Loose items such as coins could fall 

between basket and tub or may block pump. It may be necessary to call 

for service to remove items.

Washer not level.

Water may splash off basket if washer is not level. 

Fill hoses not attached tightly.

Tighten fill-hose connection. 
Make sure all four fill hose flat washers are properly seated.

Drain hose connection.

Pull drain hose from washer cabinet and properly secure it to drainpipe 

or laundry tub.

Check household plumbing  

for leaks or clogged sink  

or drain.

Water can backup out of a clogged sink or drainpipe. Check all  

household plumbing for leaks (laundry tubs, drain pipe, water pipes, 

and faucets.)

Fill hose washers.

It is normal to hear metal items on clothing such as metal snaps, buckles, 

or zippers touch against the stainless steel basket.  

Objects caught in washer 

drain system.

Clicking or metallic 

noises

Gurgling or humming

It is normal to hear the pump making a continuous humming sound with 

periodic gurgling or surging as final amounts of water are removed during 

the spin/drain cycles.

Washer may be  

draining water.

Check the following for 

proper installation:

Unbalanced loading can cause basket to be out of alignment and cause 

water to splash off tub. See “Using Your Washer” for loading instructions.

Washer not loaded properly.

Check the following for 

proper installation or see 

“Using Your Washer” 

section.

Not enough water  

in washer

Load not completely covered  

in water.

This is normal operation for an HE low-water washer. The load will not be 

completely underwater. The washer senses load sizes and adds correct 

amount of water for optimal cleaning.  See “What’s New under the Lid.” 
IMPORTANT: Do not add more water to washer. Adding water lifts the  

garments off the washplate, resulting in less effective cleaning.

Washer may not be level.

Humming

You may hear the hum of the sensing spins after you have started the washer. 

This is normal. Sensing spins will take several minutes before water is added 

to the washer.

The sensing light is on.

Washer won’t run or fill, 

washer stops working 

or wash light remains 

on (indicating that the 

washer was unable  

to fill appropriately)

Check for proper water supply. Both hoses must be attached and have water flowing to inlet valve.

Both Hot and Cold water faucets must be turned on. 

Check that inlet valve screens have not become clogged.

Check for any kinks in inlet hoses, which can restrict water flow.
