The electrolux dishwasher i30 error is a code worth taking seriously the moment it appears. It means the flood switch in the base of the dishwasher has sensed water where it should not be, which is a real leak rather than a settings issue or a simple restriction like the i20 drain alert.
Unlike most dishwasher codes, i30 is a protective measure: the control is telling you it has found standing water under the tub and, on many models, will stop the cycle to prevent further leaking or flood damage to your floor.
What the electrolux dishwasher i30 error means
A float switch sits in the base pan under the tub specifically to catch leaks before they reach your kitchen floor. Water gets there from a cracked hose, a loose fitting at the pump or inlet valve, a torn door gasket that lets wash water escape during the cycle, or a genuine crack in the tub itself. Once the float rises past a threshold, the control posts i30 and, depending on the model, halts operation.
What to do right away
- Turn off the dishwasher and shut the water supply valve under the sink before doing anything else.
- Open the door and look for standing water in the base, and check the floor and cabinet around the unit for signs of an ongoing leak.
- Inspect the door gasket around its full length for a tear, a stiff section, or debris holding it open.
- Do not run another cycle until the source is found — running a dishwasher with an active leak risks real water damage to flooring and cabinetry.
If you can see the source clearly, such as a torn gasket or a loose hose clamp you can safely tighten, that may be all it takes. Our Electrolux dishwasher error-code guides cover i30 alongside the related i10 and i20 alerts.
When it needs a technician
If the leak source is not obvious from outside, the problem is likely inside the base — a cracked hose fitting, a failed pump seal, or a hairline crack in the tub — and needs the unit accessed properly to diagnose. This is not a repair to improvise, both because of the water-damage risk and because the flood switch itself occasionally needs testing to confirm it is not the actual problem.
Why acting fast matters here
Unlike a drain restriction that mostly inconveniences the next wash, an electrolux dishwasher i30 error means water has already reached a place it is not designed to be, and cabinetry, subfloor, and flooring can absorb that moisture quickly, especially in an older kitchen without a fully sealed base. Even a small, slow leak left unresolved for days can lead to swelling or warping in surrounding cabinetry that costs far more to repair than the dishwasher problem itself, which is why this code deserves same-day attention rather than being added to a general to-do list.
