Dishwasher flood alert
Anti-flood system activated
Stop and inspectDishwasherElectroluxBuilt-ini30
The dishwasher has detected water in the base tray, so the anti-flood protection has stopped normal operation.
- 1Turn the dishwasher off and close the water supply before restarting it.
- 2Check around the door seal, inlet hose, and drain path for visible leaks.
- 3Do not keep forcing resets because standing water can damage internal components.

Typical question: What should I do first if water is already in the tray?

This scenario points to poor airflow through the dryer. In many cases the fix starts with cleaning rather than repair.
- 1Clean the lint filter completely, not just the visible surface layer.
- 2Inspect the condenser and lower airflow path for dust build-up.
- 3Restart after cleaning and only escalate if the warning returns quickly.

Technician likelyFridge freezerSamsungNo FrostEr dH
The control system is not seeing the expected defrost-heater response, so ice build-up and cooling problems may follow.
- 1Move sensitive food if temperature stability is already dropping.
- 2Avoid repeated resets because they can hide a hardware issue without fixing it.
- 3This is usually a technician job involving the heater, sensor, or wiring path.
