Electrolux Washer - 20 Error Code

The washer detected low water level during heating.

Meaning

The washer detected low water level during heating.

Error 20 indicates that the washer attempted to heat water but detected that the water level was too low for safe heating. Electrolux commercial washers use a pressure sensor to verify that the drum contains enough water before energizing the heating element. If the water level drops, fails to rise, or is misread by the pressure system, the washer halts heating to prevent overheating, steam bursts, or damage to the heating element. This error is common in facilities with inconsistent water supply or partially blocked pressure hoses.

Symptoms

  • Washer stops during the heating phase
  • Error 20 appears early in the wash cycle
  • Water level appears lower than normal
  • Washer may drain and retry filling

Causes

  • Insufficient water intake
  • Blocked or kinked pressure hose
  • Faulty pressure sensor
  • Slow‑opening inlet valve
🔧

Step-by-Step Fixes

  • Verify that the washer has reached the correct water level before heating.
  • Inspect the pressure hose for blockages, kinks, or detergent residue.
  • Test the pressure sensor for stable, accurate readings.
  • Check the inlet valve for delayed or restricted opening.
⚠️

Safety Notes

  • Do not operate the washer if the drum is underfilled during heating.
  • Disconnect power before servicing pressure or heating components.
