What Does Error E04 Mean?

The Hisense Dishwasher E04 error indicates a malfunction related to the drain pump, often resulting in unusual sounds and failure to drain water. This error may suggest a water overflow due to drainage blockages or issues with the float switch that detects water levels. When the E04 code appears, the dishwasher may stop mid-cycle or fail to start, possibly indicating water in the base tray triggering an overflow safety alarm.

Common Symptoms:

  • E04 displayed on control panel
  • Dishwasher stops mid‑cycle or will not start wash
  • Possible water in the base tray triggering a float/aquastop alarm

Possible Causes

  • Water overflow or leakage detected triggering overflow safety (aquastop) (medium)
  • Drainage blockage or drain pump/hoses obstructed (medium)

How to Fix Error E04

DIY Fix Check for water overflow and clear blockages

  2. Check underneath and inside the dishwasher for standing water; if present, remove water from the base tray.
  3. Inspect and clean filters and drain hose to remove debris or kinks.
  4. Ensure the dishwasher is level and not tilted causing water to accumulate.

  5. Reassemble and test dishwasher under normal operating conditions.
