hi there! i had a look inside my front loading washing machine to
inspect an intermittant tripping mcb problem and carefully removed the
motor to vacuum it from carbon dust.to make this easier i laid down
the machine on its side.

turns out it was clean but when i replaced it & refitted belt, drum is
now making a bad loud friction metalic sound at every revolution at a
certain position, even when spinned by hand. machine operates ok
except this sound.

what could i have done wrong? thanks
