Electrolux Dishwasher: overfilling

Professional Repair Guide

What is this symptom?

Is your Electrolux dishwasher overfilling during the fill cycle? This issue can lead to leaks and water damage, as the appliance may accept too much water and fail to shut off. Common causes include a faulty water inlet valve or a stuck float switch. Addressing these problems promptly can prevent further complications.

Urgency: Medium

Important Tips for Electrolux Models

  • Electrolux support specifically notes inlet valve failing to shut off leads to overflow.
  • Some user cases reported checking water inlet solenoid and float assembly when overfilling persists despite valve replacement.

Possible Causes

Faulty Water Inlet Valve (does not shut off)

How to Identify: Dishwasher continues drawing water even after fill; water rises above normal level; continuous hiss or water flow sounds.

Part: Water Inlet Valve

Stuck or Faulty Float Switch/Assembly

How to Identify: Float does not rise or is stuck, preventing proper water level detection; visual inspection shows float not moving freely.

Part: Float Switch and Float Assembly

Faulty Water Pressure/Level Sensor (electronic or pressure-based)

How to Identify: Dishwasher fills unpredictably or shows error codes related to water level (e.g., i20; sensor tests fail.

Part: Water Pressure Sensor/Level Sensor

Blockage or Drain Issue Causing Misinterpretation of Water Level

How to Identify: Water not draining properly between cycles; residual water appears high; may be mistaken for overfill.

Part: Drain path and pressure hose
