Amica ZZM 447 E dishwasher showing E4 overflow error and water leaking underneath

Hello
I bought a built-in dishwasher. The guy who assembles my furniture hooked me up. I wanted to use it for the first time. I refill the detergents, pack something (seriously there is not much there) and turn it on and you get an E4 error and water leaks underneath.
(error E4 according to the instructions:
Error description: Overflow
Action: Inlet water level too high)
I will add that I removed some of the dishes, so it won't hurt to check, I turn on hooray, the dishwasher works after 2 minutes, the same error pops up, but the water does not flow anymore. I have no idea what this is about.

Overfilling means overflowing with water, not overfilling the dishwasher with dishes

But how to fix it? I have literally the same case.

Hello,

I had the same case. The following message appeared on the display: Error E4 Inlet water level too high. The day before my differential broke, but I didn't know why. Only when the dishwasher refused to obey and this message appeared, I associated the facts. Well, I pulled the dishwasher out of the building and saw what was happening. In my case, a hose popped out of the connector located on the upper housing. I replaced the clamp with a twisted one, wiped the water off, dried it and so far everything is fine.
I am writing this because I was looking for such information before and I did not find anything about this error.
If I helped someone, that was the point.
Regards

I will also throw in my experience with these dishwashers. This error is caused by the activation of a contact connected to the float located at the bottom of the dishwasher housing. It detects water leaks, when the system is leaking and water spills out of the dishwasher - it is blocked. In my case, just like the predecessor, the hose from the washer at the top slid off. This can be quickly checked without unscrewing the dishwasher, because usually it is enough to pull out the soundproofing mat. After correcting this hose, draining the water from the bottom of the dishwasher, the problem disappeared.
