During a wash cycle a machine making any form of grinding, knocking, or buzzing noise is a major red flag and should be checked as soon as possible. These noises suggest the possibility of defective bearings, worn out spray arms, or deteriorating circulation pumps. Ignoring repairs can also increase your appliance replacement frequency. Attending to repairs early on can help prevent complicated kitchen workflows, reduce kitchen clutter, and lead to finer repairs for a cheaper cost. Don’t delay, prompt repairs bring efficiency and peace of mind.
