[Solved] Bosch SRV53M03EU - how to remove the water jacket and hydrostat for cleaning?

After 8 years of trouble-free operation, the dishwasher did not want to draw in water. After reading a few tips, I concluded that it was time to clean the water jacket and hydrostat. The hydrostat is very dirty - you can see it on one of the photos. The first thing I did was pour some baking soda solution into the hydrostat tank.
It helped because the dishwasher "caught" and works properly, but it still gets a little tired when taking in the water and everything is still very dirty.

I would like to take it all off and clean it properly and I don't see how to do it right now when it is installed in the dishwasher. Is there any option to clean it without removing it?

Unfortunately, I do not know how to remove the water coat. In the rear part at the top there is such a translucent plastic - like a corner that I can not remove - I marked it with an arrow in the picture.
The one in the front came off without a problem. I would not like to break it, so I am asking for tips on how to do it. I tried to undermine him from all sides, he bends but does not want to go down.

Almost exactly where you marked the arrow you will find a screw on the torx20 and it will go down after goodness, the front corner comes under force (from below), after removing the crossbars fastening the coat you need to gently tilt and pull up (water will pour out), then disconnect the hoses. The hydrostat chamber also comes under pressure.
Clean the hydrostat chamber and the pipe connecting it to the washing bowl, leave the coat alone.

Access to this screw is from the back (I cannot access the dishwasher now)?
How to clean it? I thought to fill it with vinegar - can it?

By the way - can you remove the hydrostat without removing the coat?

If you look at this plastic from behind, you will notice it immediately.
You cannot remove the hydrostat without dismantling the chamber.
A flat screwdriver and a brush are enough to clean, you don't have to dip.

Okay, you managed to clean the entire hydrostat, and the dishwasher works nicely and draws water.

However, I noticed that after starting the program water does not run through the pipe, which is on the right side of the dishwasher (photo). From what I can see it feeds water to the sprinkler on the right wall of the washing chamber. I did not follow the entire program, but stopped it after about 15 minutes when it was still pouring cold water, so maybe it is only later that the water is delivered through this pipe? How is this with it?

This is a pipe to nowhere, venting the washing chamber. The distribution and emptying of water in this construction is carried out only through the water jacket and its arrangement.

Ok, everything is clear I thought water was going to flow that way Thanks for the help!
