Ariston LDF12314 Dishwasher Error A:5 - Water Supply and Filter Cleaning Checked

Hello.
The dishwasher, as in the topic, starts working, tries to pump out the leftovers, you can hear that it is taking in water (it's not very good for me), you can hear that it is pumping out the water. After a while, error A:5 is displayed and work is stopped. I can't find what this error means. I checked the water supply - OK, I cleaned the sieve and filter without dismantling the device.

Pressure switch signal the error A05 when the low or high water pressure is present.
Check pump.

I'm reviving the topic for those looking for answers!!!

Hotpoint Ariston LSF 835 dishwasher
after starting the program, the error "A 05" appeared during filling and after a while the water was pumped out. After checking the strainers and measuring the washing pump to see if there was a short circuit/crossover, I checked it after blowing out the hydrostat/prestostat and the supply line, it started to roar - was probably suspended. (the hydrostat is located on the bottom right)

I am repeating the issue of error A-5
Error A-5 occurs for the Ariston Hotpoint LFF8314EXEU dishwasher. very similar symptoms. The error occurs irregularly. Most often, before starting the washing pump in various washing cycles (it will release water, draw in new water and error A-5 occurs, sometimes at the beginning of the program, and sometimes before the final rinse after pouring the heated water. The washing pump has been replaced - C00257903, the pressure switch - C00274118, the jacket water with turbine – C00256546.
The hose connecting the pressure switch with the bathtub was checked (patent, no water in the hose, no cracks). The contacts inside the pump starting stepper motor were cleaned - C00256972. According to the information we have, error A-5 for Indesit dishwashers means A05 - The pressure sensor has not been reset.
How to perform testing? What could be the reason ?

This error means nothing more than a clogged hydrostat chamber
A simple test is to pour 1.5 liters of clean hot water into an empty dishwasher, unplug the hose from the hydrostat and blow into it with a compressor, then the slimes remaining in the hydrostat chamber will appear in the dishwasher.

I confirm the post above, everything was checked, I also blew the hose from the pressure switch and still the error. Only when I blew it out with a compressor did the lumps come out and it runs like new. Thank you.
