Re: neff integrated washing machine w5320xogb….vibration
First off, who installed it ?
I would insist they come back and check the installation as 90{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} of noisy/vibrating new washing machines are due to poor intalls.
The transit bolts may not have been removed, the feet aren’t levelled correctly, the floor itself may be to blame also.
You really shouldn’t need any extra securing if the appliance is installed correctly.
