Dishwasher stops mid-cycle and displays E1; sometimes beeps repeatedly and will not continue the wash.

Safety first: Unplug the dishwasher or switch off the circuit breaker and turn off the water supply before working on the unit.

Step-by-step checks:

• Verify water supply: Make sure the water shutoff valve (usually under the sink) is fully open. Confirm other faucets in the home have normal pressure.
• Inspect inlet hose: Pull the dishwasher out slightly and check the water inlet hose for kinks, sharp bends, or crushing. Straighten or re-route as needed.
• Clean inlet filter screen: Turn off water, disconnect the inlet hose from the dishwasher. At the water inlet valve connection, locate the small metal or plastic screen and gently clean it with a soft brush under running water to remove sediment.
• Check for leaks at connections: Reconnect the hose firmly and ensure no drips at the valve or shutoff.
• Test fill: Restore power and water, then run a short cycle. If E1 returns quickly, the water inlet valve may not be opening fully and should be tested with a multimeter or replaced.

When to stop: If you smell burning, see arcing, or are not comfortable working with plumbing or electricity, stop and contact a qualified technician.
