11477 fills and immediately drains water ⇐ Hotpoint-Ariston

Good afternoon. The dishwasher began draining water immediately after filling, indicators 1 and 3 were flashing. Moreover, if you open and close the door during a fill, the cycle proceeds normally, either until the end, then until the next fill... I took it apart, no leaks are visible. Where to dig? Thank you.
