What does ER mean. When running our dishwasher it came up with ER where the time remaining and also the left side said washing sensing and sanitized and on the right side it said drying delay and low and constantly blinked . Could not shut it off at all. We also have a hard time starting it when we hit the start cancel button. We have notbeen happy with this dishwsher at all. Please tell us what to do if this comes up again.
