The Baggies were under scrutiny in the build-up to their trip to Norwich after reports of a dressing-room bust-up.
The incident followed a 95th minute equaliser for Cardiff the previous weekend but Ridgewell believes the frustrations all came out of a heart to succeed.
Berahino opted not to take action against his colleague and both featured on Saturday as Albion moved up to 16th in the Premier League standings.
"We are just happy to get the points after a difficult time last week and we showed what we are all about," Ridgewell told the Daily Star.
"You call what happened last week a fall-out, but we call it wanting to win. But we made sure we came here and put in a good performance.
"We showed what a good team we are. We came here to get a victory and we did just that."
Berahino was accused of poor decision-making which led to the Cardiff equaliser, but the England Under 21 international brought an injection of creativity upon his second-half introduction at Carrow Road and Ridgewell hailed the talented forward.
"He got a good cheer, but why shouldn't he? People have made a lot of what happened but everybody makes mistakes," he added.
"Saido has got some good goals this season and he did well here. But it's all about character and the whole squad showed just how much they care with this performance."
Pepe Mel's side are now five points clear of the relegation zone, but with Tottenham visiting The Hawthorns next before a testing trip to the Etihad Stadium to face title-chasing Manchester City, Ridgewell knows there is still work to do.
"This win pushes us up the table and gives us some breathing space," he claimed. "We've got 32 points now, but that's not enough, I think we need 37 or 38.
"So it's not 'job done' yet and we can still go down."
