AEG washing machine emits a sewage or rotten egg smell from the drain hose or during draining; no error code.

Safety first: Unplug the washer and wear gloves when handling dirty plumbing.

• Clean standpipe or sink trap: Remove and clean the sink trap or have the standpipe professionally cleaned.
• Flush drain hose: Disconnect the hose and flush with hot water and a mild disinfectant.
• Check hose height and loop: Ensure the hose has a high loop to prevent backflow from the sink or drain into the machine.
