Please check if the machine is leveled or use a spirit level to keep the machine steady or use a rubber mat to check , in case the floor is too much polished. Also check if the machine wobbles. if so check the drum movement or the suspension.
I found the manual on a website which I didn't note down, but which was very useful as it had almost every washing machine manual on the planet! Now I know that the energay saving and deep rinsing buttons are activated by pressing them in. Thanks anyhow for your attempt to help!
