Noisy electric water pump during bleeding procedure

I was surprised by the amount of noise coming from the water pump when speeding up and slowing down during the 12 minute automatic bleeding process. It sounded like the screetchy noise a worn out bearing would produce.
Before the coolant change I read many posts about it and seem to remember that some people wanted to know, how they could tell the pump was working at all, because they could not hear anything.
There is no CEL.
