Yes, the brushes need to bed in.

Wash should be so quiet that you have to look to know it is running.
Spin,
(ours is 1400rpm bosch ) makes a little noise, but hey, its so little
compared to anything else.

I've never heard anything so bloody daft as "the brushes need to bed in"!!!
Oh Please!!

In fact, are there any brushes??!! Most new appliances use induction motors.

Even so, the bedding in of brushes in a fallacy.

It's probably a bearing and if anything like our NEW Hotpoint will need a
replacement within weeks.

New brushes don't make noise - poor quality or badly lubricated bearings do!
Manufacturers these days use the cheapest possible bearings and don't use
much (if any) grease.



Brushes bedding in my arse!
