Bearings are going, lots of noise from drum when

You have diagnosed the problem yourself. Now you need to get a quote for the repair, which is a major job. Call around your local repairers and see if they will give you a rough estimate, without having to pay for a call out.

You might find it is better to replace the machine.

Also always best not to overload the machine. For example a 5Kg machine does not mean that it will take 5KG worth of dry towls. Imagine the weight of the towls once soaked. That will probably be 3 bath towls max.

Good luck.
