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

  • Internal water leak detected (medium)
  • Door seal/gasket failure or improper seal (medium)
  • Clogged or kinked drain hose / drainage issue leading to water accumulation (medium)

How to Fix Error i30

DIY Fix Check for leaks and water accumulation

  1. Turn off and unplug the dishwasher
  2. Carefully pull the dishwasher out and inspect under/around for water in the base pan
  3. Look for any obvious puddles, drips or wet spots

DIY Fix Inspect door seal and drain hose

  1. Examine the door gasket for cracks, debris, or misalignment
  2. Clean the gasket and ensure it seats properly when the door closes
  3. Check the drain hose for kinks, twists, or blockages and straighten/clear if found

Technician Only Service leak detection components and internal inspection

  1. Remove lower access panel and inspect anti‑flood tray and water sensor switch
  2. Test and replace faulty seals or float/leak sensors as needed
  3. Check internal plumbing (inlet valve, hoses) for damage

Parts needed: Leak sensor/float switch, Door gasket/seal, Drain hose/connector

🛑 When to Call a Pro:

  • If internal components (e.g., leak sensor, wiring) need diagnosis
  • If water damage is extensive or recurring after basic checks
