What does Frigidaire Dishwasher Leaking - Causes & Fix mean?

Water in the leak pan triggers the i30 fault. Most often caused by oversudsing, a loose hose, or a door seal issue.

How do I fix Frigidaire Dishwasher Leaking - Causes & Fix?

Follow the step-by-step diagnosis below. The most likely fix is identified by checking power, sensor resistance, and control-board signals in order — using a multimeter and the part numbers documented in the parts reference table.

Can I keep running the equipment with this fault active?

Generally no. Faults on Appliance units are emitted when a sensor, safety, or control circuit is outside its operating envelope. Running through an active fault risks compressor, heater, or control-board damage. Diagnose and clear the fault first.

What part is most commonly replaced for Frigidaire Dishwasher Leaking - Causes & Fix?

The most frequently replaced parts for Frigidaire Dishwasher Leaking - Causes & Fix are listed in the Parts Reference section of this guide with OEM part numbers and typical price ranges. Check the table for direct replacements.

Is Frigidaire Dishwasher Leaking - Causes & Fix a DIY repair or do I need a technician?

Sensor swaps, fan motor replacements, and condenser cleaning are typical DIY-level repairs. Anything involving refrigerant, gas, or high-voltage (>240V) work requires a licensed technician for both safety and code-compliance reasons.

Frigidaire Dishwasher Leaking - Causes & Fix

Frigidaire Dishwasher Leaking — What’s Happening

When a Frigidaire dishwasher shows a leak symptom, it usually corresponds to the i30 fault code. This means water has been detected in the leak pan beneath the tub, and the machine has entered a leak-protection mode to prevent floor damage.

The i30 fault is specific to water in the base pan. It is not the same as i20, which is a drain or complete-drain fault. Many techs see customers report “leaking” when the real issue is either an actual component leak, oversudsing from too much detergent, or a door that isn’t sealing properly.

Most Likely Causes

Oversudsing from detergent Too much detergent or the wrong type creates foam that spills into the leak pan and triggers the i30 fault.
Door not sealing properly A gasket obstruction, misaligned racks, or damaged door seal allows water to escape during the cycle.
Loose or damaged hose connection The inlet hose or drain hose can loosen over time or crack at the fittings, dripping water into the base pan.
Failed pump or pump seal A worn circulation pump seal or cracked pump housing leaks water into the pan below the tub.
Tub or sump seal leak Seals around the sump or tub joints can degrade and allow water to seep into the leak pan during normal operation.
One-time spill or splash event A large spill during loading or an overloaded tub can put water in the pan without any component failure.

How to Diagnose and Fix

Turn off power at the breaker or unplug the dishwasher before any inspection work.
Check the display to confirm whether the fault is i30 (leak pan water) or i20 (drain restriction), since these require different diagnostics.
Pull the dishwasher forward and inspect the base pan for standing water or dampness.
Open the door and look for excessive suds or foam in the tub, which points to a detergent issue rather than a mechanical leak.
Inspect the door gasket area for obstructions, damage, or gaps, and check that racks and spray arms are not blocking the door from closing fully.
Trace the inlet hose and drain hose from the back of the machine to their connections, looking for drips, cracks, or loose clamps.
Examine the circulation pump, sump area, and visible tub seals for wet spots or active drips while the machine is off.
If the pan was triggered by suds or a spill, dry the leak pan completely, correct the detergent amount or loading, and run a test cycle to verify the fault clears.

When to Call a Pro

If you find active water dripping from the pump, sump seals, or tub joints, or if the leak pan continues to fill after you’ve corrected detergent and door issues, call a qualified appliance technician. Internal seal and pump repairs require disassembly of the lower machine components and proper torque on fasteners. A pro can also test for intermittent leaks under pressure and verify that the i30 fault clears after the repair.
