Dishwasher Lower Spray Arm WPW10491331

Took less than one minute

Replaced Arm spray...
Turn it left and it comes off......place new spray in .. turn it right...and it's in...make sure it moves freely.......Arm wasn't turning and water was consistently hitting the front door.....I also replaced the door seal...

The new lower spray arm fit right into place. All set, and I will always check to see if it is sitting properly!

I simply removed the melted spray arm, then set the new spray arm in place, twisted the built-in securing nut (clockwise to its stop), and it worked without any problems.

The top and bottom parts of the lower wash arm were separating. This caused water to spray out the ends of the wash arm and come out the front of the dishwasher. In addition this water was not spraying upward resulting in dishes not getting cleaned. Took me a while to figure this out but the repair was simple.

The air just unscrews with one twist and the new arm twist right back on. No tools needs. Saved me $100 service call.

Something had been loaded in the dishwasher that had gone thru the basket - it hit the arm sprayer and broke it off.

Replacement sprayer was exactly the same - the partselect website has very specific identification method so you get the proper part. You must have your model number.

I watched a you tube video which was referred by part select. This was helpful.

I did not realize at first that only part of the arm sprayer had broken off. The arm sprayer broke off, but there is a base to the arm sprayer that was still attached to the dishwasher. So I could not, of course , fit the new arm with its base over the existing base because they are the same size. Once I realized this, it was a simple replacement, following the youtube instructions. You do have to press and turn counter clockwise to get the old base off, but once that was done, the new sprayer arm, which arrived attached to the base, easily fit, and press hard to turn it clockwise to reattach it..

It has worked perfectly. It is a hard turn to get the arm sprayer off or on, which is good so it doesn't come loose during washing, but when replacing it, you aren't sure of why it won't turn. It is a hard turn. Watch the you tube video.

Pulled up old spray arm and snapped new on in place. Took less than a minute and no tools. Dishwasher is like new again.

After replacing the door seal and the dishwasher still leaked a lot of water out the bottom of the door, I read posts by a couple of other DIY who said the lower spray arm can split at the seam and cause this. One post noted it is very difficult to determine if this is the problem, that you may have to take the blade of a screwdriver and try to pry the seam apart gently to see if a gap does appear with very little force being applied. If so, then just imagine what happens when that very hot water makes that plastic more flexible and then the seam opens and forces waves of water against the lower door. I could see a small seam split using that strategy and when I replaced the spray arm, my leak stopped. I don't regret replacing the door seal as it had a couple of small tears and hard water deposits all over it, so it was time to do that even though it was not the culprit for the extensive leak. The arm is SO EASY to replace, just twist the plastic nut under it and it pops right off. Put the new one on and twist the nut the other way and it secures it.

lower wash arm cracked by spinning into items hanging out of bottom of basket. part twists and snaps right in. glue did not fix.
