At least 189 Electronic Voting Machines (EVMs) malfunctioned on Monday and were replaced during the second and concluding phase of Assembly elections across 61 constituencies in Assam.
Election Commission officials said the number was likely to go up as reports from some remote areas were still coming.
The highest number of EVM malfunctioning has been witnessed in Hojai election district.
“We have changed 33 machines at different places in three constituencies – Lumding, Jamunamukh and Hojai. Some machines developed very minor errors, but we did not take any chance and replaced them,” Hojai Returning Officer Kaberi Barkakoty Sarma said.
The units developed problems such as not emitting a beep after a vote was cast, low battery, slow functioning and display error, she said.
Barpeta Returning Officer Ashwani Kumar said 19 machines were not working properly during the polling exercise in nine constituencies and were replaced.
