Dishwasher shows E24; water remains in the bottom and the machine may stop shortly after starting.

Safety first: Unplug the dishwasher. Water may spill when disconnecting hoses.

• Check sink drain: Run water in the sink and ensure it drains quickly. A blocked sink trap can cause E24.
• Inspect drain hose connection: Remove the drain hose from the sink trap or standpipe. Clean any debris from the connection point.
• Check hose routing: Ensure the hose is not kinked or crushed behind the dishwasher and that it forms a high loop to prevent backflow.
• Flush hose: If possible, flush the drain hose with water from a tap or garden hose to clear internal blockages.
• Clean internal filters: Remove and clean the dishwasher filters and sump area.
• Test cycle: Reconnect everything and run a short program to confirm proper draining.
