The problem with the starboard engine cooling system was discovered on Friday night and led to a delayed arrival in Poole.
Saturday’s sailing times then had to be amended to ensure that the crew got enough rest hours before starting work again.
Those delays, which have been compounded by tides, were also due to affect sailings scheduled for Sunday and Monday.
All sailings have been delayed by around five-and-a-half hours.
In a statement Condor said: ‘Condor Liberation’s engineering team has worked hard overnight, alongside technicians from the engine manufacturers, to rectify the technical issues suffered onboard Friday and therefore she will operate to a revised schedule.’
