What causes Frigidaire Dishwasher i30?

Over-sudsing from hand or dish soap, too much dishwasher detergent, detergent put directly in the tub, or spilled rinse aid (Frigidaire lists all of these as leak causes). A loose or leaking connection at the water inlet valve or supply hose. The dishwasher not level, so water runs toward a corner of the door. Door not fully closed (Frigidaire notes the kick plate can sometimes stop it closing completely). A clogged filter or glass trap, or soil buildup in the sump. On a new install, a drain hose installed wrong, blocked, or a disposer knockout plug left in. Loose sump hoses or a leak in the sump area (technician check per the Electrolux service manual). An overflow float stuck in the up position, so the code shows even with a dry pan (per the service manual's float check and repair guides).

How do I fix Frigidaire Dishwasher i30?

Press Cancel, then turn the dishwasher off at the breaker so the drain pump stops, and close the water supply valve under the sink. Wipe up any water on the floor and keep it away from outlets and cords. Open the door and look for suds in the tub. If you find them, rinse them out, wipe up any spilled rinse aid, and from now on use only automatic dishwasher detergent in the dispenser at the recommended amount (or one tablet). Check the supply hose at the water inlet valve for a loose connection, drips or kinks. Check the dishwasher is level side to side and front to back, and that the door closes and latches fully with nothing (including the kick plate) in the way. Clean the filter and glass trap and clear any food soil from the sump. If the dishwasher was just installed, check the drain hose is installed per the guide and not blocked, and that the disposer knockout plug was removed. Give the base pan time to dry so the float drops. Repair guides note this can take a day or more unless the pan is dried by hand, which means removing the kick plate or pulling the dishwasher out. Restore water and power and run a short cycle while you watch under the sink and at the front for drips. If i30 returns, the leak source needs finding.

When should I call a pro for Frigidaire Dishwasher i30?

i30 comes back after the pan has dried and you've ruled out suds, the inlet connection, leveling and the door. Water is leaking from inside the cabinet: the sump, sump hoses, pump seals or hose clamps. The Electrolux service manual checks start there. The pan is dry but i30 stays on and the drain pump keeps running, which points to a stuck or faulty overflow float switch or its wiring. Removing the dishwasher from the cabinet or working on the base pan, sump or float switch. The dishwasher was installed within the last 30 days (Frigidaire says to go back to the installer) or is under warranty. Call Frigidaire at 1-800-944-9044 rather than opening it up.

Frigidaire Dishwasher i30: Leak or Overflow in the Bottom Pan (Meaning, Causes, Fixes)

Q: What does Frigidaire Dishwasher i30 mean?

i30 on a Frigidaire dishwasher means water has been detected in the bottom (base) pan under the tub, from a leak or an overflow. The dishwasher stops washing and runs its drain pump to keep water from building up. Start by turning off power and water, then look for suds from the wrong detergent, a loose water inlet connection, or a dishwasher that isn't level. Frigidaire's owner's manuals list i30 as "A leak or overflow of water has been detected in the bottom pan" and tell owners to look for loose connections at the water inlet valve and make sure the unit is properly leveled. Some models show the same code as E30. Electrolux's dishwasher technical service manual (5995668042), which covers the same Frigidaire/Electrolux platform, explains what happens: the unit stops and the drain pump runs continuously. Its technician checks are loose sump hoses or leaking around the sump, whether the overflow float is in its lower position and moves freely, and soil buildup in the sump. Because the code comes from a float that water lifts, it won't clear until the pan is dry and the float drops back down, which is why some owners see i30 go away on its own a day or two later. Frigidaire's general rule for its error codes is to press Cancel or turn the breaker off for 5 minutes, and to call Frigidaire Customer Care at 1-800-944-9044 if that doesn't clear it.
