Error code E10 on the electrolux ecovalve EWF1087 front load washer. What does this mean?

E10 is a timeout code. I found the answer on google by refining my search criteria. The tap was not turned on enough for the washer to fill up in time before the timeout was reached. After restarting the washer and turning the tap on further, the washer cycle completed without error.

Family code E10 visible to customers (E11,E12 and E13 only visible in service mode) means the problem with fill water during washing or drying phase.
Possible malfunctions: Tap closed or water pressure too low; Drain tube improperly positioned;
Water fill solenoid valve is defective; Leaks from water circuit on
pressure switch; Pressure switch defective; Wiring defective; Main board defective
