Water backup in the sink is one of the most obvious indications that the dishwasher is blocked.

  • Also, if you smell bad aromas emanating from the dishwasher, particle buildup may be the cause.
  • The spray arm may be blocked if the dishwasher is loud throughout the cycle.

  • A blocked dishwasher may also be the result of mineral buildup in hard water.
