Problem with the dishwasher, where to dig? ⇐ Hotpoint-Ariston

[saruar]

Good afternoon Ariston 41566. The washer stopped starting. I thought the problem was in the aquastop hose. I removed it and replaced it with a regular hose, turned on the water and water began to constantly flow into the dishwasher without stopping, the startup cycles never started, the dishwasher only drained the water even when selecting any mode. Where to dig further? Why doesn’t my dishwasher stop filling with water? I open it and there is water up to the door and it keeps coming.
