My whirlpool DU900 spray tower came off of the nozzle cap. I can not figure out if it was glued on, or what. Even if I was able to re-attach it somehow, the bottom rack would not close, as it is sticking up. Thanks in advance for any help. Can send pics!
I got the same problem and spent a couple of days trying to figure it out. The solution is extremely simple - you just snap the tower to the bottom tray. You need to lift the tray, insert the tower through the middle cell of the tray, and just snap it on it. That's it - no bolts, no connectors, nothing.
I had the same problem and thanks to derofeyev I figured it out. I thought I would post some pictures for those who might still be confused. Lift tray and put tower through.
I found it helps to twist it into position. So start with in the tower like this:

If you are speaking about the filter behind the spray arm in the tub:
grasp the tower (the top post above the spray arm)
and unscrew it. CCW under and in the center of the tower hole thus revealed is a philips screw and fiber washer holding the spray arm on remove these then remove the arm. next, using a flat screwdriver un-snap the filter cover
Hi, you may want to try looking at all the holes in the spray arms. If you see anything blocking a hole, use the tweezers and remove the stuff. Remove the bottom spray arm and check for items in the water delivery hole.Check the lower spray tower that is connected to the bottom rack. Make sure all rotating parts rotate properly. Look underneath to make sure nothing is stuck in the tower. Remove any stuff stuck that is preventing rotation or clogging the tower.
To prove it when you have it running use a spray bottle and spray around the wires starting at the distributor and lastly spray the coil tower. do this late at night then you can see the sparks and see why it is so affected by wet situations.
The failure is a crack in the coil tower.
RECOMENTADTIONs listed below:
1. Replace coil.
2. Use a old oil wire and cut away the wire insulator and slide under the existing coil wire all the way to the base.
3. Use black electrical tape and neatly wrap the coil tower.
If the spray tower is not in place then water will not get to the spray arm for the upper rack. You should be able to re-install the tower. Look for small tabs at the bottom that fit into slots in the mounting. The tabs should snap in or lock when the tower is turned slightly. If the tabs are broken off you should replace the tower. You can use the dishwasher without it but he dishes on the top rack will not get cleaned and the pressure tot he bottom spray arm may be reduced causing dishes to not get completely coean.
I take it, it turns over ok.Spray the ignition wires with WD-40,that's a water displacer. If it starts ok then, replace the wires. If still no start then spray the distributor cap. It may have a crack in it (that you can't even see). If there's moisture inside the cap, you've found it.Finally try spraying the ignition coil tower ( where the big wire comes out). That can be cracked too.
There have been many versions of the spray tower used over the years. If you have the model HDA3400G which you posted under, you should get a part number WD22X10008 which is the lower spray arm and tower assembly. By looking at the new part, you will see how a couple tabs hold the part on, and can figure out how to remove the old one with a flat blade screwdriver (or two). If you have a different model, please post the exact model number. The model number sticker is generally located on the left side wall of the tub, right by the front.
The Spray tower fits in the bottom rack, Its actually pretty obvious as there is no way it can sit int he position it has to without being in the rack itself otherwise the rack and tower would block each other all the time.
Examine the base of your spray tower it should have two "clips" or plastic protusions that will, with a circular twist, snap onto the bars of the middle of the rack itself. Then when in place and your rack is slid inside the dishwasher the tower should sit directly over top of the exact middle of your bottom spray arm.
