Electrolux dishwasher — Error Code i30

What it means

The i30 error code on an Electrolux dishwasher is a critical fault indicating that the anti-flood sensor has detected water in the bottom base pan (drip tray). Electrolux dishwashers are equipped with a styrofoam float switch located in the lowest part of the chassis, beneath the main wash tub. When a leak occurs—whether from a faulty door seal, a cracked wash motor housing, a loose hose clamp, or an overfilling issue—the water pools in this pan. As the water level rises, it lifts the float, which engages a microswitch. Once the main electronic control board receives this closed-circuit signal, it immediately halts the active wash cycle, displays the i30 code, and forces the drain pump to run continuously to prevent property damage. The drain pump will often keep running even if the door is opened, stopping only when power is disconnected or the water in the base pan is removed.

Likely Causes

1. 1
   Leaking Circulation Pump or Wash Motor

   The O-rings or the plastic housing on the main wash motor can degrade or crack over time, causing a steady drip into the base pan during the wash cycle.
2. 2
   Defective Water Inlet Valve

   If the inlet valve fails to close completely mechanically, water will slowly seep into the tub, eventually overflowing the sump and spilling into the base pan.
3. 3
   Damaged Lower Door Seal

   A torn, brittle, or misaligned bottom door gasket allows wave action inside the tub to splash water past the door lip and down into the chassis.
4. 4
   Loose or Cracked Drain Hose

   The internal section of the drain hose routing from the drain pump to the external cabinet can develop pinhole leaks or loosen at the clamp, spraying water during the pump-out phase.
5. 5
   Stuck Anti-Flood Float Switch

   Occasionally, there is no leak at all. The styrofoam float can become mechanically jammed in the 'up' position by debris, or the microswitch itself can short closed, sending a false positive to the control board.

How to clear / reset

To temporarily clear the i30 error and stop the drain pump from running continuously, you must disconnect power to the dishwasher by unplugging it or flipping the circuit breaker. Next, you need to remove the water from the base pan. You can do this by pulling the dishwasher out from the cabinets and carefully tilting it backward at a 45-degree angle to drain the trapped water onto a towel. Once the base pan is dry and the float switch drops back to its resting position, restoring power will clear the code. However, if the underlying leak is not repaired, the i30 code will return as soon as water pools in the pan again.
