Woodford United are still searching for their first UCL Division One point of the season after they were beaten 4-0 at Harrowby last Saturday.
But there were again encouraging signs from the bottom-of-the-table Reds, who kept this match scoreless until the second half.
But once Harrowby had broken the deadlock on 46 minutes, they eased to a comfortable victory.
Woodford are back on the road on Saturday when they travel to Rothwell Corinthians in the league.
They kick off their NFA Junior Cup campaign on September 28 when they host Peterborough Sports.
