FAQ

Can detergent cause Samsung dishwasher error codes?

Yes. Too much or incorrect detergent can create foam, leading to drain and leak errors.

Why does 5E occur even if the sink drains?

The dishwasher’s filter, pump, and hose can clog independently of the sink.

Is it safe to keep resetting the dishwasher?

No. Repeated resets without fixing the cause can lead to leaks or component damage.
