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:

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

Possible Causes
