Safe dishwasher leak checks

4 steps
  1. 01

    Stop use and close the water supply

    Use caution

    Stop the dishwasher and close its water-supply tap. If water is near electrical connections or cannot be contained safely, keep clear and arrange qualified help.

  2. 02

    Check for excessive foam

    User-level

    If there are suds or foam, stop the cycle and use only detergent made for automatic dishwashers. Hand-washing liquid or too much detergent can contribute to foam and leaking.

  3. 03

    Limit checks to accessible areas

    Use caution

    Without removing panels or pulling a built-in appliance out, look for an obviously loose visible hose connection, damaged door gasket, or a large item blocking a spray arm. Compare loading and installation with the exact model manual.

  4. 04

    Treat an internal or recurring leak as a service issue

    Professional help

    If a leak code returns, the base contains water, or no accessible cause is found, leave the water supply closed and contact the manufacturer's service channel or a qualified technician.
