Water wont stop running in ice maker

My ice maker won’t make ice so I just replaced water inlet valves and new ice maker unit. I am now having a problem with the water not shutting off. Could you please advise me, how to stop the water from running.
Thanks,
Mickey

See the attachment for the tech sheet.

Disconnect power to the valves.
If the water stops then you have received a defective valve.
