DUL300XTKT0 Whirlpool Dishwasher - Instructions

Was able to replace and repair without taking the dishwasher out. Thermostat is behind and to the left of the power junction box. Has 2 wires going to it. It is up against the bottom of tub. I used an angled mirror to see what I was doing. 1 small screw to detach and pull down thermostat. Be sure power is off before you start. Also reprogrammed defaults. Hit any button 1-2-3, 1-2-3, 1-2-3, fast and close door. Let it sit 15 min to run and re-set defaults. Now I have heat and dry dishes.

I snapped on the new part onto the track. It was that easy! :) Thank goodness the part was available from Part Select!

Removed leads from fuse and installed jumper wire (while the power was off, then turned back on) to determine that circuit board was still good. Ordered new fuse and installed using existing wire connections. Did not splice in new connectors that came with fuse. Wires were clean and good and did not want to cut and splice.

Since I had watched a repairman diagnose the problem, it was eash to reproduce how to pull the unit out from the wall and find the faulty part to remove it and replace it with the new thermistor. Two wires to disconnect and connect and repair nearly complete. Pushed it back in, screwed it back to the cabinet and installed foot plate and done.

I had removed this part several times before, it had clogged from sediment, so I had practice. That issue was resolved, but I determined the water level during the wash and rinse cycles was low, and the valve appeared to be the culprit. The trick is to remove the valve from the bracket, removing the single screw, and sliding the unit so the tangs on the bracket can be pushed to the rear and then towards the front. When you disconnect the electrical connection, then the valve can be pulled out towards the front for better access and to disconnect, if your supply hose is long enough. That makes swinging the wrench easier. Other wise it is tedious. Make sure to reapply thread tape after reconnecting the supply hose.

Replace motor/pump assembly

I pulled off the old clips and easily replaced them with the new clips and popped on the wheels.
I replaced 8 clips and 8 wheels in less than 15mins

Bent the plastic housing down holding the spinner. Slipped the top of clip in slot on top of housing. Attached spinner and bottom of clip by holding top clip and pushing bottom of clip in place. No tools were needed.

Remove upper tray and spray arm. Remove two screws retaining pipe for upper spray arm and overhead. Unscrew retainer on top of lower spray arm and remove. Gently rotate the upper feed pipe clockwise until pipe can be removed from lower pipe. You may then remove the lower pipe and bearing housing where the seal is. Reverse order for reassembly. I also replaced upper spray arm bushing. Very simple, remove one screw and the arm will come out.

Pulled everything out the front, and dug down to find a thrashed chopper assembly (like a little garbage disposal). The previous owner just tossed anything in; pop tops, plastic cutlery, etc.
Didn't pay attention to the exact installation of the chopper as I pulled it out, but, it turns out that it only goes in one way.
Used pictures and instructions I found online as a guide and didn't have any issues.
Replaced the check valve because it isn't expensive and I was in the neighborhood.

Removed first part of the broken part from the top rack of the dishwasher from below.

Removed the screw from the bottom of the sprayer arm to release the second half of the broken part.

Threaded new part in sprayer arm and replaced screw.

Attached part to top rack of dishwasher from below. This part was difficult. (The part appeared to be a little larger than the original.) It was a two person job, one person pushing down on the rack and the second pushing upwardand inward on the part it click to click it into place. Dishwasher now works great.

Very simple. We had to remove the screws holding the metal cover on the inside of the dishwasher to access the electrical panel. Then we disconnected the wires that were connected to the fuse kit, unclipped the kit from the panel, clipped the new one on, and replaced the wires. Then all we had to do was screw the metal cover back onto the inside of the door and it worked just fine.

1) Remove the racks

2) Unattach the feed tube the runs from the bottom of the dishwasher tub along the back to the top (this is the grey plastic tube that the top rack sprayer plugs into). This is done by unclipping the tube in two places, one stainless clip is in the back of the tub and one stainless clip is on the top of the tub.

3) After the tube is loosened from the clips, give the tube a 45° twist clockwise (relative to the bottom of the tub) and then pull up. This should remove the entire feed tube and bottom sprayer assembly.

4) There are now 4 stainless steel torx screws visible on the bottom of the tube. Remove the screws using a torx driver. Remove the grey plastic "gear looking" piece that was held in by the screws by pulling straight up.

5) On the left hand side of the tub you will see one more (smaller) torx screw. Remove this screw and then with a pair of plyers, give the housing piece that was held on with the screw a tug straight upwards. There is a post sticking straight up that will help you do this.

6) The grinder assembly is now visible, and in my case, completely jammed with paper. Pull the grinder and screen out of the groove it is sitting in.

7) Place the new grinding and screen into the groove. The grinder blade will have to be pull back (toward you) so the grinder coupling teeth can properly engage with the motor coupling teeth. This may take some fiddling.

8) once the grinder is installed, reverse all the steps starting at step 5.

I looked up the most common problem with this model and it was the chopper assembly. I removed everything down to this. Sure enough, mine was broken off and the screen was completely clogged with debris. It was not difficult to replace, but it did take me a few minutes to slide it in to place. Ladies, you can do this. No need to call a repairman! Look up the repair manual and see where the assembly is. I had no idea it was even there. My dishes are spotless now.

.The easiest way to complete the impeller and chopper motor replacement is to disconnect the power, water and drain line, remove the dishwasher from the cabinet, set the washer on its back.

From this point everything is visible, pump housing, motor, etc. and it's a matter of disassembly and reassembly. Make note or a drawing of where all the wires are connected so you reconnect them in the right spots.

Reinstall water lines and power and check for leaks before replacing shield or kick plate.
