Introduction
The Moulinex OW500300 is a bread maker for up to 1.5kg dough. It has 1650 W and 2 heating elements top and bottom and thus it is very good in cooking the bread on all sides and producing a good crust. Unfortunately it lacks an on/off switch and so I decided to open it and add one and also it needed some care.
Tear Down
Unfortunately it's not an easy process and I didn't found a useful tutorial on the Internet.
Start
The machine is quite bulky and heavy (5.5kg) and when you carefully examine the outside of the machine you can see it is divided into 2 parts, e.g. there is a column along the sides. The column is where the two halves connect with plastic clips and screws on the inside but I learned the hard way that also the upper half (cover) is secured by the opening, e.g. baking chamber made of metal! Specifically the side element of the metal baking chamber can be separated from the bottom chamber.
Therefore one must first loosen all screws in the baking chamber and also from the 2 heating elements and try to pull out the upper plastic cover and the metal side element at the same time.
Like I said I learned it the hard way and I did pretty much destroyed a few things, especially many plastic clips and screws of the halves and even some of the baking chamber but eventually I succeeded. The machine is also a bit old and some screws were a little bit rusty and a bit hard to loosen.
