Frigidaire Dishwasher Error i30 — What It Means & How to Fix It

What Does This Error Mean?

Error i30 means your Frigidaire dishwasher's flood protection system has activated because water was detected leaking into the base pan under the tub. The machine locks itself out to prevent further water damage to your kitchen floor. You must find and fix the source of the leak before the dishwasher will run again.

Common Causes

Door gasket (seal) is worn, cracked, or misaligned, allowing water to spray out
Water inlet valve is leaking at its connection fittings
Pump housing seal or sump gasket has deteriorated and is dripping
Drain hose connection inside the machine has come loose
Accumulated condensation in an older machine has reached the float switch level

How to Fix It

Do not run the dishwasher again. Turn off the circuit breaker for this appliance and shut the water supply valve under the sink.

Continuing to run a leaking dishwasher will worsen any water damage under your cabinets.
Pull the dishwasher forward slightly (after disconnecting power and water) or remove the lower kick panel to access the base pan. Use towels or a wet/dry vacuum to remove all standing water from the base pan.

Once the base pan float switch is no longer floating in water, the lockout will clear after a power reset.
With the tub empty, inspect the door gasket all the way around. Look for cracks, tears, gaps, or sections that have peeled away from the channel.

A damaged door seal is the most common cause of i30. Replacement gaskets cost $15–$30 and can be pressed into the channel without tools.
Inspect all hose connections visible from the front: the drain hose where it connects to the pump, and the water inlet valve supply line. Feel for dampness or white mineral deposits (a sign of a slow drip).

Loose hose clamps are easy to tighten with a screwdriver. Cracked hoses need replacement.
After drying the base pan and fixing any visible leak, restore power and run a short rinse cycle while watching from the front (with the kick panel off) for any dripping.

This confirms the leak is sealed before you fully reinstall the dishwasher.
If the base pan is dry and no leak is visible but i30 returns, the float switch in the base pan may be stuck in the raised position. Locate the float switch and gently press it down to release it.

A stuck float switch causes a false i30 even with no water present. Clean around the float with a dry cloth.

When to Call a Professional

Error i30 always means water has physically escaped the tub — this is not a sensor glitch. You must identify and seal the leak before using the dishwasher again, otherwise water damage to your kitchen sub-floor will continue. If you cannot find the leak source after inspecting the door seal, hoses, and pump, call a technician — a slow drip from the pump housing or inlet valve fittings can be difficult to locate without running the machine under observation.

Frequently Asked Questions

Is error i30 dangerous? Should I be worried about mold?

Yes — any water leaking under your dishwasher can soak into the sub-floor and cabinet base, potentially causing mold if not dried quickly. Dry the base pan and the area under and around the dishwasher as thoroughly as possible, and allow it to air out for 24–48 hours before reinstalling.

Can I reset error i30 without fixing the leak?

You can clear the code by drying the base pan and resetting power, but the error will return immediately on the next cycle if the leak source has not been fixed. Never ignore i30 — it always indicates real water where it should not be.

How much does it cost to fix Frigidaire dishwasher error i30?

If the door seal is the culprit, the gasket costs $15–$30 and takes under 30 minutes to replace yourself. If the pump housing seal has failed, parts and labor from a technician typically run $150–$250.
