EASTON, Pa. - A malfunction in new voting machines forced a ballot recount in Northampton County.

Election officials worked overnight after Tuesday's election to re-scan paper ballots. The state had advised the county to recount paper ballots instead of using the machines' counts.

Northampton County Executive Lamont McClure and representatives from ES&S, the company that makes the voting machines, have scheduled a news conference for Wednesday afternoon to address the issues.

They'll discuss the results and the performance of the new voting machines in the 1 p.m. news conference in council chambers, according to a news release from the county executive's office.

The unofficial results after the recount were posted Wednesday morning. 

Among the top races recounted were those for district attorney and common pleas judge. Democrat Terry Houck edged out Tom Carroll for DA. Democrats John Morganelli and Abe Kassis will fill the two open judge seats.

Voters in the county had reported irregularities while voting on the new ES&S ExpressVote XL machine, officials said.

Multiple employees from the Elections Office and ES&S worked throughout the day Tuesday to address reported issues. 

ES&S told the county and the Pennsylvania Department of State it is "assessing and diagnosing" what caused the issue with the machines, Hess said.

"While it is unfortunate that Northampton County experienced these problems during the November 5th election, we anticipate being able to complete the count using the machine generated paper ballots and we are grateful to the Department of State for requiring all Pennsylvania voting machines to produce a paper trail," Hess said.

In 2018, Governor Tom Wolf ordered all counties to have a voting system with a paper trail in place by the 2020 elections after widespread election interference in 2016 in more than a dozen states including Pennsylvania.

The new machines in Northampton County cost about $2.8 million.
