A malfunctioning dishwasher can be a major inconvenience, especially when you have a full load of dirty dishes. One common issue is a dishwasher that won’t drain. Here are some possible reasons why your dishwasher might not be draining properly:
Clogged Drain
- Food particles: Food particles can clog the drain, preventing water from flowing out.
- Hard water deposits: Mineral buildup can clog the drain over time.
- Foreign objects: Small objects like coins or silverware can get stuck in the drain.
Faulty Drain Pump
- Burnout: The drain pump might have burned out due to excessive use or a power surge.
- Mechanical failure: The pump’s internal components may have malfunctioned.
Blocked Vent Tube
- Debris: Debris can accumulate in the vent tube, restricting airflow and preventing proper drainage.
Incorrect Installation
- Improper leveling: If the dishwasher isn’t leveled correctly, it can affect the drainage system.
- Incorrect plumbing: Improperly connected drain lines can cause drainage issues.
Software Glitch
- Control board malfunction: A software glitch in the control board can prevent the dishwasher from draining.
How to Troubleshoot a Dishwasher That Won’t Drain
- Check the drain filter: Remove and clean the drain filter to remove any food particles or debris.
- Inspect the drain hose: Ensure the drain hose isn’t kinked or blocked.
- Run a drain cycle: Run the dishwasher on a drain cycle to see if the water drains properly.
- Check for a clogged vent tube: If the dishwasher is still not draining, inspect the vent tube for any blockages.
- Reset the dishwasher: Unplug the dishwasher and wait a few minutes before plugging it back in.
