What To Know
- The air gap is a small device installed on the sink or countertop that prevents contaminated water from flowing back into the dishwasher.
- The dishwasher control board is the electronic brain that controls all the functions of the dishwasher, including the drain cycle.
- If the control board becomes faulty or damaged, it may not be able to send the correct signals to the drain pump, resulting in drainage problems.
A malfunctioning dishwasher can be a major inconvenience, especially when it fails to drain properly. If you’re experiencing this issue with your Asko dishwasher, you’re not alone. This blog post will delve into the potential causes and provide step-by-step solutions to help you resolve the problem and restore your dishwasher to its optimal performance.
Clogged Drain Hose
One of the most common reasons for a dishwasher not draining properly is a clogged drain hose. Food particles, grease, and other debris can accumulate over time, creating an obstruction that prevents the water from draining effectively. To fix this:
1. Disconnect the drain hose from the dishwasher and the sink.
2. Use a drain snake or a wire hanger to remove any visible clogs.
3. Flush the hose with hot water to remove any remaining debris.
Blocked Air Gap
The air gap is a small device installed on the sink or countertop that prevents contaminated water from flowing back into the dishwasher. If the air gap becomes blocked, it can create a vacuum that prevents the dishwasher from draining properly. To clear the air gap:
1. Locate the air gap and unscrew the cap.
2. Remove any debris or food particles that may be blocking the opening.
3. Reinstall the cap and ensure it is tightened securely.
Faulty Drain Pump
The drain pump is responsible for pumping the water out of the dishwasher. If the pump becomes faulty or damaged, it may not be able to generate enough pressure to drain the water effectively. To diagnose and fix a faulty drain pump:
1. Listen for unusual noises during the drain cycle. A humming or grinding sound may indicate a problem with the pump.
2. Check the wiring connections to the pump. Loose or damaged wires can prevent the pump from functioning properly.
3. If necessary, replace the drain pump with a new one.
Kinked Drain Hose
A kinked or bent drain hose can restrict the flow of water and prevent the dishwasher from draining properly. To fix this:
1. Inspect the drain hose for any kinks or bends.
2. If found, carefully straighten the hose and ensure it is not pinched or obstructed.
3. Reattach the drain hose to the dishwasher and the sink.
Clogged Filter
The dishwasher filter traps food particles and debris to prevent them from entering the drain. If the filter becomes clogged, it can restrict the flow of water and cause drainage issues. To clean the filter:
1. Locate the filter, typically found at the bottom of the dishwasher.
2. Remove the filter and rinse it thoroughly under running water.
3. Reinstall the filter and ensure it is securely in place.
Faulty Dishwasher Control Board
The dishwasher control board is the electronic brain that controls all the functions of the dishwasher, including the drain cycle. If the control board becomes faulty or damaged, it may not be able to send the correct signals to the drain pump, resulting in drainage problems. To diagnose and fix a faulty control board:
1. Check for any visible damage or blown capacitors on the control board.
2. Use a multimeter to test the voltage and continuity of the control board.
3. If necessary, replace the control board with a new one.
Other Potential Causes
In some cases, the following issues can also contribute to a dishwasher not draining properly:
- Faulty water inlet valve
- Broken door latch
- Clogged spray arms
- Damaged float switch
If you have ruled out the above causes and your Asko dishwasher is still not draining properly, it is recommended to contact a qualified appliance repair technician for further assistance.
