Wizz Air Airbus A320-200, performing flight from Brussels Charleroi to Cluj, had been de-iced and was accelerating for takeoff when the crew rejected takeoff at low speed due to disagreeing airspeeds.

The aircraft returned to the apron, was de-iced a second time, taxied to the runway and rejected takeoff a second time.

A passenger reported they were officially told that during de-icing a sensor got clogged with ice although no de-icing was performed in front of the pitot tubes to avoid clogging the tubes.

The aircraft was able to depart on its third takeoff and reached Cluj with a delay of about 4:15 hours.
