Why does my washing machine keep overflowing every few months?
Washing machine overflows caused by a repeatedly clogging air tube and pressure switch will keep happening if only cleared temporarily with hot water, vinegar, or a syringe. This leaves homeowners stuck in a bimonthly maintenance cycle that eventually risks severe water damage and mold in floors and ceilings.
