Common Causes of Dishwasher Not Fully Draining
- Clogged Filters and Drain Hose
- Damaged Drain Pump
- Faulty Check Valve
- Improper Installation
Clogged Filters and Drain Hose
The most common cause of a dishwasher not fully draining is a clogged filter or drain hose. Over time, food particles, grease, and other debris can accumulate and block the filters and drain hose. This prevents the dishwasher from draining properly and can cause water to pool in the bottom of the dishwasher.
Damaged Drain Pump
The drain pump is responsible for removing water from the dishwasher. If the drain pump is damaged or malfunctioning, the dishwasher may not be able to drain properly. A damaged drain pump can also cause unusual noises during the dishwasher cycle.
Faulty Check Valve
The check valve prevents water from flowing back into the dishwasher after it has drained. If the check valve is faulty, water may flow back into the dishwasher and prevent it from draining properly.
Improper Installation
Improper installation of the dishwasher can also cause drainage issues. If the dishwasher is not level, water may pool in the bottom and prevent it from draining properly. Additionally, if the drain hose is not installed properly, it can cause kinks or blockages that prevent water from draining.
