The actress appears in Walford for a single episode tomorrow night (September 27) as she takes on the role of Naomi, who is the latest love interest of returnee David Wicks (Michael French).
Naomi and David will cause chaos for Carol Jackson and Masood Ahmed, interrupting a romantic night in that the couple are enjoying at the Butcher house.
Speaking on ITV's Daybreak this morning, Maxwell commented: "It couldn't have been better. It was pretty much a four-hander, the episode. We had rehearsals, which apparently is unheard of at EastEnders, so it was a really lovely experience."
Asked whether there is scope for Naomi to return, she replied: "Well, she doesn't die at the end. There's always that. Yeah, I think she could. She could come back. She's in love with David Wicks and they've been having an affair for quite some time, from what I gather, so there's unfinished business there.
"I did love it. I did enjoy it. If the experience working on EastEnders is anything like the one I had doing that episode, then in a heartbeat I'd go back."
The former Bill cast member also confessed that she is nervous about her episode being broadcast tomorrow evening.
She said: "I might even actually watch the repeat as opposed to the first one! There's something really nerve-wracking about watching it with the nation. It's a big show, isn't it? The reaction to just being in that one episode has been quite overwhelming."
EastEnders airs Maxwell's guest appearance tomorrow at 8pm on BBC One.
