What Does Error i30 Mean?

The Westinghouse Dishwasher error code i30 indicates a water leakage detection issue, triggered by the internal anti-flood device. This error often halts the dishwasher mid-cycle and may be accompanied by water accumulation in the base pan, constant operation of the drain pump, and visible leakage around the unit. Common causes include a door seal failure, a clogged or kinked drain hose, or an internal leak. Immediate inspection is recommended to prevent further damage.

Common Symptoms:

  • Dishwasher stops mid‑cycle with i30 displayed
  • Water present in the base/pan/tray beneath the dishwasher
  • Drain pump running constantly in some models when error appears
  • Possible visible water leakage around the unit

Possible Causes
