What to do when your dishwasher won't fill

A dishwasher that doesn't fill with water when you press Start is little more than a place to hide dirty dishes. First, make sure that the water supply cut-off valve is open. If it is, try this easy fix: check whether an object is preventing the overfill float from moving up and down freely. If the float is stuck in its highest position, the fill valve won't let water into the tub.

If that doesn't take care of it, the overfill float switch or water inlet valve may be broken. A failed electronic control board or timer could also prevent the dishwasher from filling. Watch the dishwasher not filling video for more troubleshooting tips to resolve this problem.

Common dishwasher parts that can break

• Detergent dispenser assembly—The detergent dispenser assembly is the container that holds the detergent. If your dishwasher runs a normal cycle, but is not releasing the detergent, then you might need to replace this part.
• Drain pump—The water drain pump pulls water out of the system at the bottom of the dishwasher and releases it as wastewater. If you notice water building up or pooling in the bottom of your dishwasher, then the drain pump might be clogged or not functioning properly.
• Electronic control board—The electronic control board sits on the top of the door. If the dishwasher is running too long, doen't clean the dishes or doesn't run at all, then this control board may be broken.
• Door latch assembly—The door latch is the swinging arm that seals a dishwasher closed by latching the door. Most dishwashers will not turn on if the door latch assembly is broken.
• Dishwasher spray arm—The dishwasher spray arm is the revolving arm that sprays heated water onto the dishes. If your dishes are not getting clean, then something may be blocking the sprayer arm from rotating.
