My built in dishwasher ser

Question

My built in dishwasher ser no sm843049B-Model number GSD696ON1OSS will not reset. I mistakenly used the delay wash setting. It is set at 1 hr. I have used the start/reset button several times and the delay continues to show 1 hr. I don't see that the timer is moving in any way. It seems to be "stuck" at 1 hr . Is there a way of "erasing" the previous input? D Bafkas
