Repair or replace a dishwasher: use cost, age, and leak risk

A clogged drain path may cost little. A leaking tub or multiple major failures can change the answer quickly.

Safety first Disconnect power and water only when you can do so safely. Stop for gas, damaged wiring, flooding, or instructions beyond the owner’s manual.
  1. 1

    Confirm whether the problem is installation, maintenance, or a failed part. Filters, hoses, latches, and some pumps can be reasonable repairs.

  2. 2

    Get the full repair price and ask what warranty covers the part and labor. Compare it with delivery, installation, old-unit removal, and any plumbing updates.

  3. 3

    Treat cabinet or floor damage as a separate cost. Repeated leakage can outweigh the value of keeping an older machine running.

  4. 4

    Consider performance. Poor cleaning caused by loading, detergent, water temperature, or a dirty filter does not automatically justify replacement.

  5. 5

    Replacement is usually the stronger option for a leaking tub, severe rack corrosion, or a major repair on a machine already near its expected service life.
