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
- Turn off the dishwasher and disconnect power completely
- Check inside the unit bottom (base pan) for water accumulation
- Ensure dishwasher is level and hoses (inlet and drain) are not kinked or blocked
- Reconnect power and attempt a simple reset by powering off/on
Technician Only Inspect leak detection and water level sensing components
- Remove dishwasher access panels to inspect the base pan and internal water collection tray
- Check the leak/flood sensor, float assembly, and water level sensor for proper operation and replace if faulty
- Inspect and test drainage pump, drain hose, inlet valve and filters for blockages or damage
Parts needed: float switch or water level sensor, drain pump and hoses, inlet valve assembly
- If water is visibly pooling under the dishwasher or E4 persists after clearing blockages and sensor checks
- If internal sensors or wiring checks indicate electrical faults
