What Does Error Code i30 Mean on a Frigidaire Dishwasher?

The i30 error code on a Frigidaire dishwasher indicates that water has accumulated in the bottom pan, triggering the flood protection system. This built-in safety feature is designed to prevent water damage to your home and the appliance’s internal components. When this error occurs, the dishwasher will usually stop its current cycle and activate the drain pump continuously.

Common Causes of the i30 Error Code

1. Internal Water Leak

Water may be leaking from loose or cracked hoses, a damaged tub, or worn pump seals. When enough water pools in the base tray, it lifts the float switch and triggers the error.

2. Faulty or Stuck Pressure Sensor

A malfunctioning pressure sensor may falsely detect an overflow and activate the error code, even if there’s no actual leak.

3. Excess Detergent or Suds

Using too much detergent or incorrect soap (like dish liquid) can cause foaming that overflows into the base pan and triggers the flood sensor.

4. Drainage Problems

A clogged drain pump or filter can cause dirty water to back up and spill into the base.

5. Unlevel Dishwasher Installation

If the unit is tilted forward, water may pool in the bottom tray and cause a false error signal.

What Happens When the i30 Error Is Triggered?

• The dishwasher stops mid-cycle.
• The drain pump may run continuously.
• The control panel locks out normal operation and displays "i30".
• If unresolved, the appliance may remain non-functional and experience additional internal damage.
