When your dishwasher won’t drain, it’s usually not the machine breaking down—it’s a clogged dishwasher drain, a blockage in the drainage path that stops water from leaving the tub. Also known as a dishwasher drain issue, this problem is one of the most frequent reasons people call for appliance repair in Northampton. You’ll see standing water, bad smells, or even a leak under the machine. It’s not just messy—it’s a sign something’s wrong inside the system.
Most clogs happen in three places: the drain hose, the filter, or the garbage disposal connection. The dishwasher drain hose, the pipe that carries water from the dishwasher to the kitchen drain can kink or get blocked by food bits, especially if you don’t rinse plates before loading. The dishwasher filter, a removable screen at the bottom of the tub that catches debris gets gunked up over time—many people forget to clean it, thinking the machine handles everything. And if your dishwasher connects to a garbage disposal, a clog there can back up into the dishwasher too.
Fixing this yourself takes 10 minutes and a few basic tools. Start by turning off the power. Remove the bottom rack and pull out the filter—rinse it under warm water. Check the drain hose for bends or debris. Run hot water in the sink to clear the disposal if you have one. If water still won’t drain, you might have a faulty pump or a blockage deeper in the pipe. Most of the time, cleaning the filter and hose solves it. But if you’ve tried everything and it’s still not working, the pump or control board might be failing. That’s when you need a pro.
