KitchenAid model KUD101FL

It is most likely that one of the hinge pulley cables is broken. You will have to order them by model number. They are made of cord and break after many openings. It is usual that you will have to pull the dishwasher partially out of the cabinet to replace them. I suggest replacing both sides at the same time, otherwise you will be replacing the other side soon.

check an replace door spring

Falls open when? This unit wom't operate unless the door is secure so I assume you mean the door assist springs are disconnected or broken and the door just falls heavily to the open position after you unlatch it from the closed position. Try these, part 18 here

Take a look at my other Sequoia posts about this.

You need to remove the interior pull handle first then gently pry away the interior panels from the top down. Go look at Tundra Solutions.com for the detailed procedure on the handle assemlby replacement but here is a rundown:

First, take off the license plate.
Since the hatch wouldn't open, I started from the inside and took down the top trim piece. After that the two side pieces come down, then the main trim piece which covers the bulk of the door comes out. These are all popped in with the white tabs.
There are 3 access hole covers to pop out (don't forget to install them back in when done) and through the left hole you can see the mechanism to unlatch, press it down with a screwdriver and open the door. If anytime you close the door you will have to do this to unlatch, up until you disconnect the cable and pull out the handle, then you have to locate the cable and pull that directly.
Behind the large trim piece you will find a metal access cover, remove the 7 or 8 10mm bolts holding that on and pop the 3 white tabs and let it hang off to the side. Disconnect the cable from the handle assembly by reaching in from the right hand side and popping of the cable from the handle assembly.
From the left and right access holes, locate the two 10mm nuts which hold the license plate assembly to the door and remove them. Then there are 4 plastic tabs that come in from the outside that hold the license plate assembly on in each corner, try and locate those and using some pliers squeeze them together and push it through. Next locate the license plate lamps wire connector and release that from the left side, it’s the simple push in and pull out square white connector.
After these are out, put back in 1 or 2 bolts into the large metal access cover so the hatch can be lowered (don’t close it).
Here is where I had fun, begin to pop out the assembly that it was bolted to. I ended up breaking 3 of the 4 plastic tabs in each corner because I did not use pliers from the other side to pull them out, however it remained somewhat useable (hindsight 20/20).
Now the license plate assembly can be taken to a bench to replace the handle assembly (Toyota doesn't sell just the handle, it is a small assembly). Two screws out and the assembly is replaced.
Before pressing the license plate assembly back onto the truck, make certain all the plastic tabs are in the assembly and not in the truck. Reverse the process to re-install.

Remove the front panel by removing the screws located on the inside of the door (note hold door inplace, since it is heavy and will fall out after screws removed). Unscrew screws located on bottom of plastic retainer (2 each) Remove tension spring. Note 2 are included right and left. Note color of spring on end, different springs for different door types, stainless, black,beige or white. Replace all in reverse order.

There is normally 2 heavy springs & cables that control the "falling" of the door located in the bottom of the machine or it the door itself. Sounds like one (or both) have snapped.
