Is your Bosch dishwasher leaving you in a puddle of frustration due to its inability to drain properly? Don’t despair! This comprehensive guide will equip you with the knowledge and techniques to diagnose and resolve this common issue, ensuring your dishes emerge sparkling and dry.
Common Causes of Bosch Dishwasher Drainage Problems
- Clogged Drain Hose: Debris, food particles, or grease can accumulate in the drain hose, obstructing water flow.
- Faulty Drain Pump: The pump responsible for expelling water from the dishwasher may malfunction or become damaged.
- Clogged Air Gap: The air gap, a small device located above the sink, prevents water from siphoning back into the dishwasher. If clogged, it can hinder drainage.
- Blocked Drain Filter: The filter traps food particles and debris, but if it becomes clogged, it can prevent water from draining properly.
- Kinked Drain Hose: A kink or bend in the drain hose can restrict water flow.
- Faulty Control Board: The control board manages the dishwasher’s functions, including drainage. If it malfunctions, it can disrupt the drainage process.
- Dirty Float Switch: The float switch detects the water level in the dishwasher. If it becomes dirty or clogged, it may not trigger the drain cycle.
Step-by-Step Troubleshooting Guide
1. Check the Drain Hose
- Inspect the drain hose for any visible clogs or kinks.
- If necessary, disconnect the hose from the dishwasher and sink and clean it thoroughly with hot water and a drain cleaner.
2. Test the Drain Pump
- Locate the drain pump at the bottom of the dishwasher.
- Listen for a humming sound while the dishwasher is running. If you don’t hear a hum, the pump may be faulty.
- To test the pump, disconnect it from the wiring harness and apply 12 volts directly to the terminals. If the pump doesn’t run, it needs to be replaced.
3. Inspect the Air Gap
- Find the air gap installed above the sink.
- Remove the cap and check for any clogs or debris.
- Clean the air gap with a small brush or pipe cleaner.
4. Clean the Drain Filter
- Open the dishwasher door and locate the drain filter at the bottom.
- Remove the filter and clean it thoroughly with hot water and a brush.
- Reinstall the filter securely.
5. Check for Kinks in the Drain Hose
- Inspect the drain hose along its entire length for any bends or kinks.
- If you find any kinks, straighten the hose and secure it to prevent future bending.
6. Reset the Control Board
- Unplug the dishwasher from the power outlet.
- Wait 30 seconds and then plug it back in.
- This will reset the control board and may resolve the drainage issue.
7. Clean the Float Switch
- Locate the float switch at the bottom of the dishwasher.
- Remove the float switch and clean it with a soft cloth and soapy water.
- Reinstall the float switch securely.
Additional Tips
- Regularly clean the drain filter to prevent clogs.
- Use a dishwasher cleaner monthly to remove grease and debris buildup.
