In most Spokane homes, the dishwasher drain hose connects directly to the garbage disposal. When the dishwasher empties, that water has to pass through the disposal to exit the system. If something is wrong with the disposal, the dishwasher is often the first place you’ll notice a problem.
One common issue occurs when a new garbage disposal is installed and the internal knockout plug is not removed. This blocks the dishwasher drain completely, causing water to back up into the dishwasher or sink. However, clogs inside the disposal, grease buildup in the drain line, or partial blockages downstream can cause the same symptoms.
If your dishwasher isn’t draining, drains slowly, or leaves standing water after a cycle, the issue isn’t always the appliance itself. It’s often a plumbing problem tied to the disposal or shared drain line. Ignoring it can lead to recurring backups, foul odors, or even water damage under the sink.
