Frigidaire Dishwasher: error code i30

Professional Repair Guide

What is this symptom?

Is your Frigidaire dishwasher showing error code i30? This indicates that the internal leak detection system has detected water in the base pan, halting normal operation. The dishwasher will not start or complete a wash cycle until the issue is resolved, often running the drain pump continuously. Possible causes include actual leaks, sensor faults, or drainage issues.

Urgency: Medium

Important Tips for Frigidaire Models

  • Error code i30 specifically indicates leak detection triggered by water in base pan and is common across many Frigidaire dishwasher models.

Possible Causes

Water in the base pan / internal leak activating the anti‑flood system

How to Identify: Water present in the bottom tray of the dishwasher; code appears and drain pump runs continuously; float switch actuated by water level. (Frigidaire Appliance Support

Part: Leak detection float switch and base pan

Clogged or faulty pressure sensor/float switch

How to Identify: Dishwasher thinks there’s water in base when there isn’t; float may be stuck, debris on sensor; error clears only after cleaning/repair. (Fleet Appliance

Part: Pressure sensor / flood float switch

Unlevel dishwasher causing water pooling

How to Identify: Water not draining properly; level check shows unit is off plumb front‑to‑back or side‑to‑side. (Fleet Appliance

Part: Dishwasher leveling legs

Drainage obstruction (filter, drain hose, drain pump blockage)

How to Identify: Water backs up into tub/base, dishwasher won’t drain; visible debris in filters; pump impeller blocked. (Fleet Appliance

Part: Drain hose, drain pump, filters

Faulty water inlet valve allowing overfill

How to Identify: Dishwasher overfills or water continues entering when not expected; valve fails continuity checks. (Dishwasher USA

Part: Water inlet valve

Cracked tub, loose connections, or component leaks

How to Identify: Actual visible leaks under/around unit; water present after cycles. (Dishwasher USA

Part: Tub seals, hose connections
