What Causes Clogs in Washing Machines?

Clogs in washing machines can arise from various factors, often leading to drainage issues or malfunction.

• Lint and Detergent Buildup: Over time, lint from clothes and residual detergent can accumulate in the washing machine’s drainage system. This buildup can lead to significant blockages, causing water to drain slowly or not at all.
