When the wiper connection goes o/c, you often get a dc offset showing
up on the output wire, creating major noise. Adding a resistor
prevents this, and can turn a very noisy pot into a silent well
behaved one, some of the time.

"When the wiper connection goes o/c ..." the pot no longer works, noise or no
noise, so replace the bloody thing!

Not at all, its common for pots to go momentarily o/c while rotating
them, and as long as its very brief its not normally noticed. If it
gets to the point where it is noticeable, then yes, its replacement
time.
