Have you read the manual. I do not know much about this type of machine but have heard that at times the water level will not be above the clothes.

Turns out there are TWO water level switch's, one for the load size, one hidden behind the control panel for rinse level.

Once apart, fixed the low water rinse level with no problem.

I now get to have the full water fill rinse cycle I desired. And BTW, from the factory this brand and model washer is set for the smallest water level for rinse mode to be a water saver.

:)

Its pretty simple to adjust. If you call a repairman out, I doubt they will adjust it, as most who I talked to said it was not adjustable.
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 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.
Thats what I did to mine, took all of 5 minutes to disasseble, fix, and reassemble

They swear though this cant be done....Ok then...And if you need factory service work, you can always change it back ;-)
I would imagine if its the same model number, unless they have changed it, which I dont think so since its so new of a model-2011 model, should be the same.

I have pictures if needed
There is a white plunger out of the end of each switch with a screw loctited 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.

No problems at all.
The entire reason I even followed up and posted that I found the fix and reviewed it at home depot is in hopes others would look for the info and use it for themselves. As this is, for its price, a decent no frills machine that is based on the same direct drive all whirlpools of this design use.
I have my own well water, and could care less about saving a few gallons of water-I would much rather opt for a full rinse level.

Thanks again. I'm not sure if it's direct drive or belt driven. When I Google "Whirlpool WTW7340XW direct drive" I get results from Sears that say yes. When I go to Lowes which is where they bought it, it only says "Two Piece Agitator/Impeller: Impeller", but it also says "Sound Reduction: Yes".

She really likes the 4 cubic ft feature and the idea of cleaning her rugs in it. She's going to win this battle it looks like. For some reason she doesn't think the Admiral will be big enough.

For $249 I know she wouldn't have been disappointed, but at $610 (by the time you add 4 yr extended warranty) the Whirlpool may not live up to what she thinks it can do. Gonna go ask her one last time and if she says no, then it is what it is hahaha.

EDIT: Yeah done deal. Lowes is installing it tomorrow....hope she likes it. But thanks again for all the information...much appreciated!
