A malfunctioning washing machine can be a major inconvenience, especially when it refuses to drain. If you’re facing this issue with your Bosch washing machine, don’t panic. This comprehensive guide will walk you through every step of troubleshooting and repairing the problem, ensuring your laundry days run smoothly again.
Common Causes of Bosch Washing Machine Not Draining
1. Clogged Drain Hose: Debris, lint, and other objects can accumulate in the drain hose, preventing water from draining out.
2. Blocked Drain Pump Filter: The drain pump filter traps small objects that may have slipped through the drum. If it becomes clogged, the water won‘t be able to pass through.
3. Faulty Drain Pump: The drain pump is responsible for pumping the water out of the machine. If it fails, the water will remain in the drum.
4. Malfunctioning Pressure Switch: The pressure switch monitors the water level in the machine. If it malfunctions, the machine may not initiate the draining cycle.
5. Blocked Air Trap: The air trap prevents sewer gases from entering the machine. If it becomes clogged, it can create a vacuum that prevents the water from draining.
Step-by-Step Troubleshooting and Repair
1. Check the Drain Hose for Clogs
Disconnect the drain hose from the back of the machine and the drain pipe. Inspect it for any visible obstructions. If you find any, remove them and reconnect the hose.
2. Clean the Drain Pump Filter
Locate the drain pump filter at the bottom of the machine. Unscrew the cap and remove the filter. Clean it thoroughly with warm water and a brush. Reinsert the filter and tighten the cap.
3. Test the Drain Pump
With the drain hose and filter cleaned, run a test cycle without any clothes. If the machine still doesn’t drain, the drain pump may be faulty.
4. Inspect the Pressure Switch
The pressure switch is usually located near the top of the machine. Disconnect the electrical connector and use a multimeter to test its continuity. If the switch is faulty, replace it with a new one.
5. Unclog the Air Trap
The air trap is located near the drain hose connection. Disconnect it and clean it with warm water and a toothbrush. Reinstall the air trap and ensure it’s properly connected.
6. Check for Electrical Faults
If you’ve ruled out all the above causes, there may be an electrical fault. Inspect the wiring and connections for any damage or loose contacts. If you’re not comfortable working with electricity, call a qualified technician.
7. Reset the Washing Machine
Sometimes, a simple reset can resolve the issue. Unplug the machine for a few minutes, then plug it back in and run a test cycle.

- Use a flashlight to inspect the drain hose and filter for obstructions.
- Wear gloves when cleaning the drain filter to avoid contact with dirty water.
- If you’re replacing the drain pump, ensure it’s compatible with your Bosch washing machine model.
- When testing the drain pump, ensure the water supply is turned on.
- If you’re not confident performing the repairs yourself, don’t hesitate to call a qualified appliance technician.
