The actress's character Val Pollard is back on screen next week following time away from the village. In real life, Hardwick had a 12-week break from the ITV1 show as she starred in comedy play The Awkward Squad.
Hardwick has now told PA that she found it easy to get back into the character of Val when she returned to filming.
She commented: "It was brilliant and I had no difficulty finding Val again. I did think, 'I wonder if I can remember her'. But the script was so well written it was no trouble.
"It's a great script, it was a pleasure to come back because the script is funny."
Next week's episodes see Val left livid when she discovers that her estranged husband Eric (Chris Chittell) has been dating Brenda Walker (Lesley Dunlop) in her absence.
Hardwick added: "Somebody is going to get punished for this and it's the other woman who dared go near Val's husband!"
Emmerdale airs Val's return on Thursday, May 24 at 7pm on ITV1.
