I'm stumped, and so are other people I've talked to....Last week, my Kenmore 90 Series washer (made by Whirlpool) stopped filling prematurely when set on full - it only filled about half to 2/3 full, and started agitating. I decided to replace the pressure switch (original Part Number 3366845). The box for the part that I got (new) has part number W10339326. Inside the box, there is rubber tubing, one hose clamp, and the new pressure switch. The interesting thing is that the new pressure switch has a part # of W10231387 stamped on the underside, which does not cross over to my model washer (at least anywhere that I have looked so far). I connected the switch, and now my washer overflows. If I unplug the washer or push in the timer knob, the water stops filling, so that tells me that the water inlet valve appears to be working as desired. I did NOT install the clamp - the box included no instructions on which end of the hose the clamp should go on - the tub end or the switch end. Do you know? Also, if I blow on the tube going to the water level switch to simulate a full tub, it stops filling and starts the rest of the cycle. If I bypass the switch with a clip leads, it works as desired. I have verified that the tubing is not damaged or cut, and I have also verified that the tube holds pressure by putting a balloon over the end and filling the tub. While it did not inflate the balloon, it did keep it firm with the air pressure from the tub being full. Is it possible I have a bad water level pressure switch that is DOA, even though it is new? According to Whirlpool (I had my supplier call their contact at Whirlpool) the part W10231387 has superseded W10339326 as of March 12, 2012, because W10339326 was no longer available. Also, I have tested this in several different wash cycles, so I don't believe it is the timer. To recap - which end of the tubing does the clamp go on? Do I have a bad pressure switch? What else could be wrong? Thanks!
ANSWER Hi Johnathon. You need to use the clamp on the new hose at the pressure switch part # W10339326. When you install the pressure switch, advance the unit into a spin mode and let it cycle through until it normally stops. This resets the pressure switch because it tells the switch the hose and the tub are clear. There has been an up grade in the part #. This is the correct part for your washer. Thank You.
