How to completely reset Bosch SPS 53E02 ⇐ Bosch

[Vladi-peace]

Good day to you...
Need help or advice. The problem is that my PMM has recently stopped producing proper pressure on the nozzles, and accordingly the dishes have stopped washing properly. In addition, it became clearly noticeable that she was beginning to become dull, spending long periods of time on various actions. I called the workshop, a master came and suggested that the engine had screwed up... Having checked the inflow and outflow of water, he assured that all the valves were working, after which, with my consent, he changed the engine to a new one, but the result remained the same. The master threw up his hands, returned my engine to its place and left. I have an assumption that there is a program failure, but the machine does not give any errors, and I don’t know how to restart or reboot it in general... Please advise if anyone knows anything... Thanks in advance
