Query about Bosch WVG30461GB tub design and serviceability

The problem

The user wanted to know whether the Bosch WVG30461GB washer-drier had a serviceable tub and bearings, or a sealed outer drum, before buying a replacement machine intended to last well.

Likely cause

The discussion indicates a concern that many modern machines, including many Bosch models, use sealed or welded plastic outer tubs, making bearing replacement difficult or uneconomic. For this specific WVG30461GB, the thread suggests it is likely to use the same type of plastic tub, but this was not conclusively verified from parts information.

What fixed it

No repair was involved. The advice given was that sealed tubs are common across modern machines and that washer-driers still use the same plastic tubs. The original poster decided to look for the machine at a good price with an extended warranty rather than obtaining confirmation of a serviceable tub.
