In the semifinals of last year, Pliskova matched or improved on her best result at the Australian Open at the beginning of the year since her debut in 2013.
However, the 2016 US Open runner-up failed to build on his performances in Melbourne Park, where he faced aggressive Pavlyushenkova in fierce resistance at the Rhode Lover Arena.
Pavlyuchenkova had a 4-1 lead in the opening set, which was highlighted by a 30-point second leg before a draw with Pliskova eventually ended in a draw.
Pliskova, who finished with 35 winners and 29 forced fumbles, recovered slowly in the second to force another tie-break, but the Czech star was unable to send the match to a decisive set.
Pavlushenkova will face off against 2016 champion and triple helmet winner Angelik Kerberg in the final 16 in two hours, after escaping within 25 minutes in two hours, after missing the match in 25 minutes.
