What Does Error E4 Mean?

The E4 error code on your Artusi dishwasher indicates an anti-flood condition caused by water accumulation in the base pan, typically due to a leak. This error activates the control system's safety measures to prevent flooding and can result from high water levels, faulty sensors, or drainage issues. Common symptoms include the dishwasher displaying the E4 code mid-cycle, not draining properly, or detecting water in the sump area.

Common Symptoms:

  • Dishwasher displays E4 code mid‑cycle or on startup
  • Dishwasher may not drain properly or appears to have high water in sump/base
  • Dishwasher may repeatedly run drain pump or refuse to start
  • Possible water detected in bottom pan or internal leak indicator triggered

Possible Causes

  • Water overflow or high water level detected by sensor (medium)
  • Faulty or misreading water level/float sensor (medium)
  • Blockage or malfunction in drainage or inlet system causing overfill conditions (medium)

How to Fix Error E4

DIY Fix Initial visual checks & resets
