What Does Error E4 Mean?

The Electrolux dishwasher E4 error code indicates a drainage issue, which may stem from excessive water entering the unit, an internal leak, or a communication failure between the main PCB and the display PCB, particularly in compact models. Users may notice the E4 code on the display along with a humming sound. This error can lead to the dishwasher stopping mid-cycle and poses a risk of water accumulation or flooding. Immediate action is required to prevent damage and ensure proper functioning.

Common Symptoms:

  • Dishwasher displays E4 code on panel
  • May emit acoustic signal (~30 seconds) on some models
  • Dishwasher may stop mid‑cycle and not proceed
  • Possible water accumulation or flooding risk

Possible Causes

  • Excess inlet water, internal water leak or overflow (high)
  • Communication failure between main PCB and display PCB (specific to integrated compact models) (high)
  • Drain or filter issues contributing to abnormal water conditions (medium)

How to Fix Error E4

DIY Fix Immediate basic checks and precautions

  1. Turn off water supply to dishwasher to prevent flooding.
  2. Turn off power to the dishwasher (unplug or circuit breaker).
  3. Check that drain hose is properly connected and not kinked.
  4. Ensure dishwasher filters are clean and not clogged.
  5. Check that sink drain connected to dishwasher is draining properly.

Technician Only Diagnose internal water fault or PCB communication issue

  1. Service technician should inspect for internal leaks or water in base pan.
  2. Check water inlet assembly and aquastop/float assembly for proper function.
  3. Inspect and test communication between main PCB and display PCB (integrated compact models).
  4. Check drain pump, drain hose, and filters under load to verify flow conditions.
  5. Replace faulty components as identified (e.g., inlet valve, float switch, PCBs).

Parts needed: Inlet water valve, Float/overflow switch or sensor, Drain pump and hoses, PCBs (main and display)

🛑 When to Call a Pro:
  • If basic checks don’t clear the error code after power and water reset.
  • If water is visibly leaking or machine base contains water.
  • If E4 persists and model is an integrated compact displaying communication fault.
