Exclusive: In Video: First-look 'EastEnders' clip
But launderette owner Mr Papadopolous looks to have found a replacement.
In our exclusive clip, a stand-in Bulgarian worker gets herself in one almighty lather, leaving Dot hanging out to dry.
An insider told DS: "Dot finally thought she'd have a lighter load on her hands when Pauline's replacement turns up, but she doesn't quite live up to Dot's expectations..."
The scene is to air at the end of the month.
