What Does Error E04 Mean?

The E04 error code on your Defy Dishwasher indicates a malfunction related to water overflow or leakage. This error is often triggered when the overflow safety sensor detects water in the base, causing the dishwasher to stop functioning. You may notice unusual noises during operation and the control panel displaying the E04 error. It is essential to address this issue promptly to avoid potential water damage.

Common Symptoms:

  • Error E04 displayed on control panel when water leaks into base or overflow sensor triggered
