Having beaten Manchester City away last weekend, Hammers fans expected a simple win against Norwich, but it was not to be.
Although Slaven Bilic's side can beat anyone away from home at the moment, their home form is struggling.
Here are five things we learnt on Saturday afternoon.
5. Mike Dean Needs Time Off
Having missed the bulk of Diego Costa's violent attack on both Laurent Koscielny and Gabriel last Saturday, Mike Dean has had one of the toughest weeks of his career.
It came as quite a shock to everyone that he was assigned a game for this weekend, and he was clearly not in the right mind set against West Ham.
Dean missed Steven Whittaker plant his elbow into the neck of Dimitri Payet, seemingly on purpose, and went on to miss a number of obvious free kicks throughout.
Mike Dean has refereed for years at Premier League level, but he needs a break as he didn't seem fully alert yesterday and it cost both sides big decisions.
4. Payet's Influence Cannot Be Overstated
Dimitri Payet is receiving great media attention for his wonderful start to life at West Ham, and rightly so.
It has become clear that when he performs, the players around him perform, and this is something welcome at West Ham as they look to improve across the board.
What perhaps isn't desirable however, is how Payet's mediocre performance against Norwich similarly affected the rest of the side.
With Payet giving away the ball and failing to create many clear cut chances, the whole side suffered, and Hammers fans will hope it's just a blip for their star player.
3. Sakho Needs a Partner
Diafra Sakho has been working his socks off all season, and away from home, his work rate draws defenders away so that the midfielders can score.
However, when the midfield players aren't on top of their game, as was the case against Norwich, Sakho is isolated and ineffective.
With the likes of Andy Carroll, Nikica Jelavic and Mauro Zarate all waiting in reserve, Sakho could quite easily be given a strike partner for when goals just won't come.
When 2-1 down against the Canaries, Bilic opted to bring on Pedro Obiang, when a partner for Sakho could have been far more effective.
2. Kouyate Is on Fire
Dimitri Payet and Diafra Sakho are gaining a lot of attention around the country right now, but West Ham's unsung hero, Cheikhou Kouyate, deserves as much praise as anyone.
Kouyate's powerful runs forward and goals have been crucial this season, and he is fast becoming one of the key men in the Hammers' side.
Although there are still a few areas of his game that need improving, Kouyate is currently a force to be reckoned with, and is an unexpected threat going forward, where the opposition usually see him as a defensive player.
Kouyate is having the best spell in a claret and blue shirt, and it seems as though it will continue.
1. Upton Park Form Continues
A win against Newcastle two weeks ago at Upton Park was expected to spell the end of their poor home form. Where the games against Bournemouth and Leicester were considered blips in their form, it now appears that the Newcastle game was just that.
With yet another massive away win against Manchester City last weekend, Hammers fans and neutrals expected nothing less than a win against Norwich.
But their is something about the Boleyn Ground this campaign, and West Ham fell behind early on for the third game this season.
Whether it's the expectation against smaller clubs, the lack of motivation without a top six opponent, or just bad luck given that it is the last year in the stadium, it simply has to change fast.
