Hi,
during the wash cycle and that has
Remove the spray arm and covers...check around the wash impellor and screens....often see stuff caught there and the macerator blade or wash impellor hits it and makes noises.
It doesn't have any.
Motor, slipping/loose/stripped seal ( where the wash impellor screws onto ) have been common noise makers....something in the drain pump is another.
