In November last year, Ritchie paid tribute to the show saying playing Sally Fletcher for 20 years was among the happiest of her life.
'It's really comforting to know that the show continues to go from strength to strength,’ she told The Daily Telegraph.
'I don't think I'll ever find anything like that again. It's a very special and unique place to work.'
She added: 'It was such a great foundation, it taught me a wonderful work ethic. I just hope it's nurturing all those young people, like it did for us.'
Ritchie is currently a radio host for Nova FM alongside Tim Blackwell and Marty Sheargold.
