Samsung Dishwasher Error Code Over-level water error / Leakage error

This error means the dishwasher's control system has detected water at an abnormally high level inside the wash tub, or water that has leaked into the base pan beneath the unit. The dishwasher stops operation automatically to prevent further water damage. Common sources include a faulty inlet valve, a damaged door gasket, or a blocked drain preventing water from exiting the tub properly.

A power reset alone is unlikely to resolve this error permanently if the underlying cause has not been addressed. If water remains in the base pan or the faulty component is still present, the error will return as soon as the dishwasher attempts to fill or run again. The root cause, whether a failed valve, a leaking gasket, or a blocked drain, must be corrected first.

Repair costs vary depending on the failed component. Replacing a door gasket is generally on the lower end of the repair cost range, typically between $50 and $150 including parts and labor. A faulty inlet valve or drain pump replacement can run between $100 and $250 or more. Diagnostic service fees from an authorized technician usually add $75 to $150 to the total cost before any parts are factored in.

No, you should not attempt to run the dishwasher while this error is active. The error indicates active or potential water intrusion that could damage your flooring, cabinetry, or electrical components. Turn off the water supply valve and set the dishwasher's circuit breaker to off until the source of the problem has been identified and corrected.

Start by closing the water supply valve and turning off the circuit breaker as a safety measure. Check the door gasket for visible damage, inspect the drain filter for blockages, and look for any moisture or pooling water under the dishwasher. Because Samsung treats this as a safety-priority fault and recommends contacting an authorized service center, a technician should perform a full inspection if you cannot identify an obvious cause.
