Why does dishwasher stop mid cycle?
Similarly, you may ask, is it bad to stop a dishwasher mid cycle?
While this myth does actually sound quite plausible, again, it's totally false. Only the bottom of the dishwasher tub (below the level of the door) fills with water. So, the next time you need to open your dishwasher mid-cycle, don't hesitate! The most you'll get is a bit of steam in your face.
Considering this, why does my dishwasher not finish cycle?
One reason the dishwasher is not completing its cycle is because the washer door is opening during the cycle. When the dishwasher door opens, the unit immediately stops all activity as a safety measure against flooding or injury.
It's best to leave the dishwasher's door open for a little while after running a cycle, as keeping it shut creates a warm, damp environment that is very comfortable for mould and other microbes. However, if your dishwasher has a water softener, there's no need for rinse aid.
