What does this error code mean?
Page 38 of the Beko BW1O3721W manual identifies E05 as water-temperature NTC failure. NTC refers to a temperature-sensing component. The user action in that table is to power off.
Do not remove or ignore the leading zero when recording the display, and do not transfer a code definition from another Beko model. Check the full model number on your appliance before using this advice.
The same manual lists E03 for abnormal drainage. Opening the pump filter is therefore not the prescribed E05 response for BW1O3721W; internal diagnosis should be arranged through service.
