WATER USEAGE How much water is used in a typical large load of wash: all cycles - wash and rinse?

This is a known issue!

You can choose second rinse or use less HE detergent. If you are using liquid no more than 1/4 cup for large load.and a little less for smaller load

I would look at lid switch on this model and plunger to lid .Under lid is spray flume that can be damaged by large loads ,check that close. put it in wash full and drop lid hard it may come on.

Pulled this together from a couple of Solutions & added some helpful tips I found as I successfully changed the rinse cycle water level!
ATW4475XQ - Admirial Water Saver washer - Adjust Rinse cycle water level
The rinse cycle water level can be adjusted. Unplug the machines power.
You can youtube a video on how to remove the top control panel, its just 2 screws on the back of it,
phillips head. Swing the control panel up, and find something to support it so you have both hands free.

You'll see a clear plastic tube coming up from the back rear like 3/8 in diameter, to a "T"
connection. The one that goes to the left, thats the wash water level switch it connects to. The one you
can adjust, large, medium, small, from the front of the panel . The other off the T goes to the rinse
water level switch. There is not a knob to adjust it. But if you look at the bottom of the lever
mechanism/cam pickups of both switchs, you will see that they are the same. Rotate the wash load size
(knob on outside of control panel) from small to large, back to small, notice how the mechanism changes?
The rinse water level swtich acts the same way, although it is only a 2 position switch, small and
large. Once you watch the wash level mechanism move from rotating it back and forth a few times, you
should be able to see how to rotate that same mechanism on the rinse switch 1 click. It will click into
place, there are only 2 positions as I said and from the factory its in small, so once it "clicks in"
dont go any further. I did mine with a very small screw driver without removing the rinse switch.
Once you get that hidden switch turned to the other position, put it back together, fire it up and now
your rinse is the large level, all the time.
NOTE: There is a white plunger out of the end of each switch with a screw located in place. Dont mess
with the screw or that plunger. As you adjust the lever mechanism/cam this adjusts the amount of that
plunger sticking out, which changes the pressure pickup for water level.

Low water pressure or bad inlet valve, or clogged screens in fill hoses, check flow with hoses disconected these will be the causes! check hot and cold fills than check warm, any differnt all setting work?

The typical cycle is;
fills to selected water level
agitates wash cycle
drains wash water
spins wash cycle
fills to selected water level on rinse cycle
agitates on rinse cycle
drains rinse water
spins final time
end of cycle

the drain hose is to low the water is syphoning out on the high loads

error code f 06 keeps coming up and we cannnot afford to have it serviced at this time we were told it had something to do with the control panel

The psi should be in the green on the gauge,20-25.The 10 second rinse cycle is the default setting.

water pump blocked with nylon stuffing from old pillow.removed front panel from hinges under the lid. water pump at the right hand corner removed hose then removed 2 cups of nylon threads and stuffing forced into pumps small openings where it was compacted to a solid mass.
