If your Maytag MDB8959SKZ dishwasher is continuously draining and won't stop, it may be experiencing a problem with its control board or drain pump. Here are some steps you can follow to troubleshoot the issue:

Turn off the dishwasher and unplug it from the power source for a few minutes. Then, plug it back in and turn it on to see if the issue has resolved.
Check the dishwasher's drain hose for any kinks or clogs. If the hose is clogged, try clearing it using a plumbing snake or by running water through it.
Inspect the dishwasher's filter and clean it if it's dirty. A dirty filter can cause draining issues.
Check the dishwasher's float switch. If the float is stuck in the "up" position, it can cause the dishwasher to continuously drain. You can try to gently move the float up and down to see if it's stuck. If it is, try cleaning it with a cloth or replacing it if necessary.
If none of the above steps resolve the issue, there may be a problem with the dishwasher's control board or drain pump. In this case, it's best to contact a professional technician to diagnose and repair the issue.

It's important to address the issue as soon as possible to prevent any further damage to the dishwasher.
