Potential Damage from Not Removing Electrolux EWB 105205 W Washing Machine Transport Locks?

I recently purchased a washing machine; Electrolux EWB 105205 W.

After a week, when I returned home, it turned out that none of the security measures were unscrewed by my sister. I found out that the washing machine was jumping all over the bathroom during spinning. Now that I have unscrewed 3 screws, everything works fine.
But I wanted to ask the experts, if the security has not been removed and has already been washed in the washing machine 7 times, does it mean that it is somehow damaged or worn?
The sister removed the security measures in the rotor, but the screws on the back of the washing machine were not removed in time.

Thank you for the advice and best regards.

I don't think the washing machine is permanently damaged. These screws are to stabilize the drum so that it does not fly during transport. The effect of not unscrewing these screws is the lack of cushioning of the drum and the effect you describe.

Akajarz, thank you for the information. I am calm, and my sister was so happy that she told you to say thank you very much

It is worth checking if water is leaking somewhere. Sometimes the drum housing is damaged (cracked) where the screws are inserted. The easiest way is to open (unscrew) the top plate of the washing machine and you can see everything. Or check the floor under the washing machine immediately after washing that it is not damp. All activities must be performed with the washing machine disconnected from the power supply - the plug disconnected from the socket !!!
