How do I open the door assembly of a zanussi wds1183w so as to access the door handle and replace it?

1. Locate the linkage that connects the door handle to the door latch mechanism. You may need to detach it from the door handle.
2. Look for any other retaining clips or screws that are holding the door handle assembly in place.
3. If the door handle assembly is still not coming out, you may need to remove the interior panel to access the back side of the door handle assembly.
4. Once you have access to the back side, inspect the door handle assembly for any additional screws or clips that are holding it in place.
5. Once you have removed all screws, clips, and linkage, the door handle assembly should be able to be pulled out of the door.

If you are still unable to remove the door handle assembly, it is recommended to refer to the vehicle's service manua

From the description of your issue it sounds as though if the door handle rod has come off inside the door. If so, in this you would have to pull the door panel to access it. Door won't open from either inside or out handle? That's going to be a bit of a trick getting it off. It couldn't be a handle broken because if it was, one handle or the other would open it but it's the rod has com off the latch assembly. If you can gain access to the inside the door at the latch side, you should be able to manually move to latch by hand to open it and replace the broken retainer clip. I hope this helps in your repair. Jesus loves you, John 3:16-17 (KJV)

there is a lever if you can pry it open a bit and get some type of hook in there and pull it across you can get it open i can get it with just a flat blade screw driver but a have had heaps of practice

take the lid off and reach down

More likel that the door latch or handle is broken.
Only way to open door now is to remove the top cover and force the door lock open from inside, you may possibly break the lock by doing this, but there is really no other alternative.

You should be able to repair your existing door. Have a look around the perimeter of the door to see if there are any screws, particularly near the handle. You are looking to take the front fascia off the door, so that you can access the inside. Most doors have the front fascia held on by small brackets glued to the back of the glass that clip on to a fixing on the internal door. The top of the fascia is normally held in place by the handle. Once you have the front of the door off you can retrieve the piece of glass that has fallen out. You will almost certainly find that the glass has come away from the adhesive that was used to hold it in place. You will need to clean up the glass and the metal door and re-stick the glass using a high temperature oven door glue

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.

take top off and see if you can feel for the door peg sticking thro the interlock and operate by hand.
also, you can chew away the door handle and operate the door peg with a small screwdriver.
the door handle kit will need replacing anyway
