A dishwasher is a valuable appliance in any household, but when it stops draining properly, it can be a major inconvenience. Fortunately, many dishwasher drainage issues can be resolved with a little troubleshooting and repair. This comprehensive guide will provide you with step-by-step instructions on how to repair a dishwasher that is not draining.
Identifying the Problem
Before attempting any repairs, it’s important to identify the specific cause of the drainage issue. Common symptoms include:
- Water pooling at the bottom of the dishwasher
- Dishes remaining wet or dirty after a cycle
- Foul odors coming from the dishwasher
- Humming or grinding noises during the drain cycle
Step-by-Step Repair Guide
1. Check the Drain Hose
Start by inspecting the drain hose for any kinks, clogs, or blockages. If the hose is kinked, straighten it out. If it is clogged, remove the clog using a drain snake or a pair of pliers.
2. Clean the Drain Filter
The drain filter is designed to trap food particles and other debris. Over time, it can become clogged and prevent the dishwasher from draining properly. To clean the drain filter, locate it at the bottom of the dishwasher and remove it by unscrewing the cap. Rinse the filter thoroughly under running water and replace it.
3. Inspect the Drain Pump
The drain pump is responsible for pumping the water out of the dishwasher. If the pump is faulty, it can cause drainage issues. To inspect the drain pump, remove the lower access panel of the dishwasher and locate the pump. Check if the pump is running during the drain cycle. If it is not running, the pump may need to be replaced.
4. Check the Air Gap
The air gap is a small device that prevents water from siphoning back into the dishwasher. If the air gap is clogged, it can cause drainage problems. To check the air gap, locate it on the countertop or sink and remove the cap. Clean the air gap thoroughly and replace the cap.
5. Inspect the Check Valve
The check valve is a one-way valve that prevents water from flowing back into the dishwasher. If the check valve is faulty, it can cause drainage issues. To inspect the check valve, locate it on the drain hose and remove it. Check if the valve is opening and closing properly. If it is not, the check valve may need to be replaced.
6. Reset the Dishwasher
Sometimes, a simple reset can resolve dishwasher drainage issues. To reset the dishwasher, unplug it from the power outlet for 30 seconds and then plug it back in. Start a new cycle and see if the drainage problem has been resolved.
7. Contact a Professional
If you have tried all of the above steps and the dishwasher is still not draining, it may be necessary to contact a professional appliance repair technician. A qualified technician can diagnose the problem and perform the necessary repairs to restore the dishwasher to proper working order.
Preventative Maintenance
To prevent future dishwasher drainage issues, follow these preventative maintenance tips:
- Run the dishwasher regularly, even when it is not full.
- Rinse dishes before loading them into the dishwasher.
- Clean the drain filter regularly.
- Check the air gap and clean it as needed.
