Question about Whirlpool Duet GHW9150P Front Load Washer
Our problem is the machine doesn't use enough water to wash or rinse the cloths. Soap is left in the cloths each time they're washed and then it sets when the cloths are dried. This allows mildew to form when they get damp from use and they start to stink! The washer stinks of mildew because there is not enough water to flush the soap from the machine after each wash and it builds up in the washer and the drain system. I've even read where people were having problems with drain flies because of the buildup. People are having to clean out the drain pumps because of gunk building up over a short period of time.
After much encouragement from my wife I decided to tackle the problem! Much encouragement!!! Once I determined that the problem was related to the lack of water we were on the way to clean cloths again. Not so quickly. Once it was determined that the machine needed more water to do the job I tried buying a replacement pressure switch, the device that controls the amount of water entering the machine, but found that it worked just the same as the one it replaced. This is when I realized that Whirlpool had a serious problem that they would not acknowledge. See my blog for the whole story and a couple of solutions that solved the problem for good!
My blog - (http://whirlpool-dueling-with-duet.blogspot.com/). You'll find a link to Mike's Blog where he solved the problem by recalibrating the pressure switch after reading my orginal blog. I told Mike that I really enjoyed my solution to the problem but that his was much more cost effective. I hope this will help others solve similar problems that they may be having with their front loading washer.
Duet Owners and others,
Our Whirlpool Duet front loader doesn't use enough water to wash or rinse the cloths.
This past weekend I decided to try a little experimentation to determine just how the
pressure switch works in the machine. I decided to replicate the function of the machine by
cutting a piece of 1-1/4" pvc pipe the height of the washer and install a hose barb at the
base of the pipe to allow connection of a piece of 1/4" clear plastic tubing that would
connect to the pressure switch. I located the switch at the same height that it is in the
machine, connected an ohm meter so that I could tell when the contact closed that indicated
full water level. I really learned a lot by doing this, none of my original ideas proved to
be true but after seeing for myself how the switch reacted to water level I began to
understand what would have to be done to increase water level in the machine without having
to make an adjustment to the switch. It really is simple after you see how it reacts.
This is what I learned. The length of tubing has very little to do with when the switch
closes, the orientation of the tube has everything to do with when the switch will close.
Let me explain by getting you to draw a simple XY graph. First draw the vertical and
horizontal axis lines, next starting at X=0 and Y=0 draw a 45deg.line on the graph go back
and add two more lines equally spaced between the X axis line and the 45deg.line, do the
same for the Y axis. Be sure to allow the angular lines to extend the full length of the X
and Y lines. It should start to look like one quarter of a spoke wheel at this point. At
this point take a kids drawing compass and draw a quarter circle with the point of the
compass located at X 0, Y 0, allow the pencil to extend to the full height of X. Everywhere
the pencil crosses a line represents water level on the X axis based on the angle of the
tub with relationship to the vertical axis. If you were able to follow my crude
instructions you should now see how the orientation of the tubing that feeds pressure to
switch is effected by the angle that it leaves the machine tub and travels to the switch.
If it’s not plain yet just draw a line at each cross point parallel to the horizontal axis
and let it run to the vertical axis. Where it crosses the vertical axis represents water
level in the pvc pipe.
I haven't opened up our machine yet so I don't know if I will be able to increase water
level with what I have learned but I plan to try. All depends on how the line is oriented
now and if there is room for me to reroute the tube in a more vertical direction as it
leaves the connection point on the washers tub. Horizontal travel is additive and once you
have reached the maximum horizontal travel allowed by the switch calibration no amount of
vertical travel will change the trip point. You have to go vertically as quickly as
possible with the line to increase water height in the machine to the desired level at
which point you want to travel horizontally to the switch.
Look at the graph you'll see how water level increases when the tube travels in a more
vertical direction and decreases as you move toward the horizontal axis.
I sure hope I can make this work because it will be a simple fix for the water problem
that everyone is having with these front loaders and want require any electrical knowledge
and better than that want require any money unless you have to add some length to the tube.
Twenty feet of the clear 1/4" tubing cost me $2.68 and about the same for the double ended
3/16" hose barb. I'm hoping someone will see this and give it a try with success and pass
it own to others. If not I'll give it a try as soon as I have time.
If anyone gives this a try please let us hear from you on how it worked out. Remember look
at the graph, when I tried filling the pvc pipe with the tubing running straight up the
pipe I was able to get 28 inches of water in the tube before the switch tripped, this is a
lot more water that your machine will hold so take it slow. I'm sure you will not be able
to find a straight vertical path but vertical adds just like horizontal as long as you get
the vertical travel ahead of the horizontal. Remember always unplug the machine before you
start working on it!!!
P.S. This has all been inspired by a guy named Joe Tass after having read his blog it got
me to think about a simple way to solve the problem. I sure hope that it works out. I'm
going to post this in the comment section on his blog as well. Good Luck All

Have you tried cutting back on detergent.. due to low water use of machine if too many suds/detergent suds and detergent may not get completely rinsed out also be sure you were using HE detergents low suds high efficent..preferably any but tide it tends to suds the most of any HE
