Here is another example of why you should always empty the pants pockets when loading your washing machine. This pump is from a rather expensive Whirlpool Cabrio clothes washer. See the little hole where the hose stem joins the body of the pump on the 1st photo? That was caused by the penny that was in the pump (see it sitting there in the 2nd photo.) The drain pump kicked that penny hard enough to punch a hole in the body of the pump. A $250 repair and a flooded basement later and the customer can do laundry again.
BTW – this unit was on the main floor of the house, so when it flooded it also ruined a section of the ceiling in the basement.
Empty the pockets folks – or keep my number handy, you’re gonna need me.
