What i30 usually means on a Frigidaire dishwasher

i30 usually indicates water in the base (or a leak sensor/float switch was triggered). Causes range from a one-time overflow/foam event to a recurring leak from hoses, pump seals, or the sump area.

Do this first (to prevent water damage)

• Stop the cycle if it’s running.
• Shut off the dishwasher water supply under the sink (turn the valve clockwise to close).
• If water is present on the floor or the unit is still running the pump, turn off power at the breaker.
• Towel up standing water and keep it away from outlets, power strips, and cords.

Quick checks you can do at home

1) Check for obvious leaks under the sink

Look at the dishwasher supply line connection and shutoff valve under the sink. A slow drip can run down and end up under the dishwasher.

2) Inspect the door seal area

A misloaded rack or debris on the gasket can cause water to leak out the front corners and make its way into the base area.

• Make sure large items aren’t preventing the door from closing fully.
• Check for food debris stuck along the door gasket and wipe it clean.
• Confirm the bottom spray arm can spin freely (items striking it can splash water toward the door).

3) Rule out “foam overflow”

If the wrong soap (like dish soap) was used, or too much detergent was added, excess foam can push water out of the door area and trigger i30.

• Make sure you’re using dishwasher detergent (not dish soap).
• If you saw lots of suds, let the unit sit and dry out before attempting another cycle.

4) Let the dishwasher dry out (sometimes i30 is “latched” by water in the base)

If i30 was triggered by a brief event, allowing the base pan to dry can sometimes clear the code.

• Leave the door slightly open to help it dry.
• Use towels at the toe-kick area to absorb any visible moisture.
• Avoid touching wires/components if you remove the toe-kick panel.

If i30 returns after it has fully dried, there’s likely a recurring leak that needs service.

5) Reset (only after water/power safety is addressed)

• Restore power after the base area is dry and you’ve confirmed no active leaking.
• Try a short rinse cycle while you watch for leaks.

Most common causes of Frigidaire i30

• Water in the base pan triggering a float/leak switch
• Door gasket leak or door not sealing due to loading issues
• Supply line drip under the sink or at the dishwasher connection
• Internal leak from sump, hoses, clamps, or pump seals
• Foam overflow from wrong detergent/too much detergent
• Inlet valve overfilling (less common, but possible)

Likely parts involved (when it needs service)

• Base float / leak switch assembly
• Sump seals, internal hoses, clamps
• Drain pump or pump seal (depending on model)
• Water inlet valve (if overfilling is confirmed)
• Door gasket (if damaged)

When to call Beacon

Call for service if:

• i30 returns after the unit dries out
• The dishwasher runs the drain pump continuously
• You see repeat water under/around the unit
• You want a technician to locate the leak source (sump, hoses, pump, or door sealing)

Our friendly technicians in yellow can find the source of the leak, confirm the base switch is doing its job, and fix the underlying issue safely.
