ESI 9620 lox does not heat water ⇐ Electrolux

[Shmel]

The car is 6 years old. Operation intensive. About a year or two ago it stopped heating the water (and drying it by itself). Somehow they continued to use it. Then she started pouring too much water. Changed the pressure switch. And she began to pour water as needed and began to heat it up. Now it has stopped heating the water again, but it pours normally.

I cleaned the pressure switch (and at the same time the combined temperature/turbidity sensor). It worked... once in fast mode, after switching to normal mode it stopped heating again.

I took it out and washed the pressure switch again. It didn’t work.

I took out the combined sensor and cleaned the contacts on it. It worked, quickly... once.

And then I realized that, in fact, the last time I took out the pressure switch, I was too lazy to lay it on its side, so I took it out like this, from the front. And the other times, I always put it on its side (on the right, where there is access to the heating element).

I put it on its side and did nothing. It worked... once.

I ask for advice on how to fix it:).
Thank you.
