I'm not quite sure what the right forums is. I have a 10 year old Siemens washing machine. At medium spin speeds there is an extremely loud rocking noise.
At low and high spin speeds there is no noise & it operates as I would expect it to.
I called out an engineer who said there was nothing wrong with it and it was because I wasn't balancing my loads correctly. However this noise is apparent on every cycle regardless of whether I wash bedsheets only, towels only or clothes only.
Any advice? Is it likely something is broken if I am only hearing the noise on medium spin speeds and not on low or high spin speeds?
