Re: wmt03 wobbly drum???
Front to rear movement is normal. I’m a little puzzled as to why you replaced the bearings yourself on a machine that is covered by a manufacturers 5 year parts warranty. you would have only paid the labour, and Hotpoint would have replaced the whole inner and outer drum assembly, and you would have been able to call them back if the repair was not satisfactory. By doing the repair yourself you have invalidated your warranty. these machines can be noisy with even the sightest unbalanced load. Is it noisy on spin when you run it without clothes in it?
NB. If you did not use the latest bearing kit with the Rubena seal then early failure of the replaced bearings is a distinct possibility sometime in the future. If the new seal you fitted had a large spring on it then that is the old type.
