The closures represent nearly one day a week without full services available at the DG One site in Dumfries.
The extent of the shutdowns was revealed in a Freedom of Information request by the BBC.
The centre’s training pool has currently been shut since May 15 with no date set for reopening.
Previous closures have hit the sports hall, main swimming pool and leisure swimming area.
A council spokesman told the BBC there had been “ongoing technical issues, particularly in relation to pool tiling”.
He said independent experts had now been hired to try to get to the bottom of the issue.
The council said once it had a full list of the remedial works needed it would hold talks with the original contractor Kier Northern.
Discussions are already under way with the company about ways of tackling the current closure of the training pool.
The spokesman stressed routine maintenance and repairs were “normal for such a facility” and could require parts of the centre to be closed.
He said: “It is necessary, however, for such maintenance to be carried out in order to ensure the ongoing operation of the facility and the safety of DG One customers and staff.”
Kier Northern said: “We have always responded swiftly to any problems notified to us, and rectified all items that were our responsibility at our cost and within timescales agreed with the council.
“We will continue to work with the council to address and resolve any issues that are the responsibility of Kier.”
