At Rooter Man, we get all kinds of questions. So we’ll let our experienced technician, Cap, answer this one.
The most significant source of a clog from a washing machine is lint. Yes, lint. We see the lint trapped in the dryer lint catcher, but there is no lint catcher in washing machines. So imagine the amount of lint sent out of your washing machine. Although the drain is usually big in diameter, the lint catches itself in the drain pipe along with detergent, soap, dirt, coins, oil, and grease. It’s a clogging mixture bound to cause problems over the years.
