The audience vote from Saturday's show will still count and the results will be revealed during this weekend's final.
The three finalists will then dance as usual and the audience will again vote, with the points from that added to those from the semi-final to determine this year's champion.
Meanwhile, judge Craig Revel Horwood urged the public to "get over" the tie break.
"It happens in the national lottery. It's not as if the judges have created a tie of that description - it just happened out of our scoring," he told Radio 1's Newsbeat.
The problems encountered on Saturday's show occurred when there was a tie between dancers Lisa Snowdon and Rachel Stevens following the judges' scoring.
Because of the way the points were then awarded, actor Chambers and partner Camilla Dallerup could not have been saved from the dance-off regardless of how many public votes he had received and that was considered by the show's producers to be "unfair".
However, the problem was not realised until after voting had started.
The situation caused the programme to end 10 minutes early, forcing BBC One to fill the gap with trailers.
