The Beko refrigerator E4 error indicates a malfunction in the defrost system, primarily linked to the defrost heater or the evaporator temperature sensor. This error typically results in incorrect temperature readings on the display, potential ice buildup on the evaporator, and abnormal operation such as water pooling from the defrost cycle. Addressing this issue promptly is essential to prevent further complications.

Common Symptoms:

  • E4 code displayed on refrigerator control panel
  • Potential ice buildup on evaporator
  • Possible abnormal operation such as water pooling from defrost cycle

Possible Causes

  • Defrost heater malfunction or break (medium)
  • Evaporator temperature sensor issue (dirty/damaged) (medium)

How to Fix Error E4

DIY Fix Basic Power Reset
