Customer centers are open but callers may face long delays, the bank said.
The company issued statements via Twitter Thursday after widespread complaints that customers could not access their accounts through online banking and apps, and that their debit cards were not working.
Wells Fargo said that the problem resulted in "intermittent outages" that also affected Wells Fargo ATMs and credit cards.
The San Francisco-based bank said Friday most of the disrupted services have been restored, but both the bank's employees and its customers had trouble accessing information on their direct deposits earlier in the day. "The transactions were processed normally, and customers can use their accounts with confidence", a Wells Fargo representative told Newsweek.
Wells Fargo will not say whether the Shoreview facility is the same main data center facility referred to in their statement, which said system issues were "due to a power shutdown at one of our facilities, initialed after smoke was detected following routine maintenance".
Wells Fargo's CEO, Tim Sloan said those kinds of transactions were restored Thursday. "This issue has now been corrected, and all transactions are now visible".
The issues come a day after the bank reported a significant outage. Customers spoke up on social media Friday, saying mobile banking either was unavailable or their paychecks had yet to show up.
On February 7, Wells Fargo officially confirmed the outage of its mobile application and ATMs, apologizing to its customers.
"I thought I was (missing my direct deposit) but I called the bank and its (sic) in there just not showing up on the mobile banking", one user said.
The incident happened at a data center in Minnesota at around 5 a.m. CST and was under control starting at 9 a.m.
Other customers said they weren't at all impacted by the issues.
Wells Fargo stock (WFC) was down 59 cents, or 1.23 percent, at $47.49 late Friday.
