The goal by Said Benrahma helped West Ham into the fourth round.
He thumped home from 25 yards after getting the ball after a tackle.
The ball went over the reserve keeper in the middle of the goal who should have done a better job.
The game lacked attacking quality and only one shot on target was fired.
The large periods of the match were spent with the ball in the middle of the field.
After the Bees played there on Monday and London Irish on Wednesday, the pitch was very heavy and the first half was very wet.
It resulted in little quality, with Yoane Wissa's effort hitting Lukasz Fabianski on the ankle, before going behind for a corner.
That was the closest the team could come to the game.
They were surprised after Thomas Frank said their Carabao Cup exit was their "most disappointing" of the season.
They lacked quality throughout the game, despite making four changes and fielding a strong side.
Tomas Soucek had a chance to score in the opening moments of the second period, but he missed a seven yard shot.
Benrahma's strike was West Ham's first on target and was a good effort.
The goal will have been a sigh of relief for West Ham and their manager, who would not have wanted a replay in between crucial games against Wolves andEverton.
It is the 10th time that the Scot has won 10 of his 12 ties in the third round of the cup.
