Bearing faults are usually not catastrophic if you can endure the noise - but it's only gonna get worse and most people rightfully hate that sound.
They can get catastrophic at some point with bearings seizing up instantly and suddenly during a spin which could cause extensive damage to many parts. So it's not something you can just ignore for ever.
So if you want to repair the machine, do it sooner rather than later.
If you want to go the replacement route, you should be abled to limp along for a dozen or so cycles without too great of a danger until the replacement arrives.
If the machine really is 10 years old, I personally would go the replacement route.
There appear to be some New Old Stock (NOS) parts you could get for like 40$ if you search for them:

At that price, if you can do the work yourself, it's a small investment and even if the control board fails in a year or so, it's an OK deal.
However, if you go for a new part at 160$, and the control board fails in a year (which at 10 years old isn't terribly unlikely), that would be something to be annoyed about.
Even more so if you can't do the work yourself and have to pay 300-400$ for the job.
