Bosch Washer Drainage Problems

Draining problems mean a washer leaves clothes soaked in a puddle of water, bringing your laundry routine to a halt. Why is my Bosch front load washer not draining? A clogged drain pump may be restricting water flow. Use these Bosch washing machine troubleshooting tips to pinpoint the problem and solution.

Bosch Front Load Washer Not Draining? Here’s How to Resolve This Common Washer Worry

Clogs and part malfunctions are often to blame for a Bosch front load washer not draining, requiring a DIY fix or professional repair. But before we address why your Bosch washer does not drain, here’s how to easily remove standing water.

1. How to Drain Water Manually

Before determining the cause of a Bosch front load washer not draining, it’s necessary to remove any remaining water in the wash tub. This can be done via the drain tube hose at the bottom of the washer.

Here’s how to drain water from a Bosch washing machine:

1. Unplug the washer and turn off its water supply.
2. Open and remove the service flap on the washer’s bottom right corner.
3. Place a shallow container under the opening to contain draining water.
4. Unfasten the drain hose and remove the plug. Allow water to drain into the container.
5. Plug the drain hose and refasten it before replacing the service flap.
6. Restore the washer’s power and water supply.

2. Obstructed Washer Drain Hose

A Bosch washer not draining properly is often due to a drain hose obstruction. The drain hose transports water as it flows through the drain pump to the sink or standpipe. Blockages are often due to kinks in the hose or clogs formed by lint, debris or foreign objects that restrict water flow.

Straightening the hose to remove the kink may restore water flow. However, if the kink caused damage, the hose should be replaced to avoid washing machine leaks. The hose must be disconnected to remove any clogs.

Follow these steps to remove drain hose clogs. If the clog can’t be reached, the drain hose must be replaced:

1. Turn off the washer’s power and water supplies and move it away from the wall to access the hose.
2. With a screwdriver, loosen the pipe clamp where it connects to the standpipe or sink.
3. Carefully remove the hose, allowing any lingering water to drain into a bucket or sink.
4. Remove any visible debris with your fingers, pliers, or tweezers.
5. If there are no visible obstructions, remove the hose connector to check for blockages.
6. Reattach the hose connector and drain hose and tighten the pipe clamp.
7. Restore the washer’s power and water supply and reposition it against the wall.

3. Need to Clear Out Drain Pump

Bosch washer drain pump problems can also cause draining issues, specifically if the pump is clogged with debris. Fortunately, the pump can be easily accessed to clean and remove blockages. Making pump cleanings part of regular washing machine maintenance can help prevent future obstructions.

These steps detail how to clean a Bosch washer drain pump:

1. Unplug the washer and turn off its water supply.
2. Open and remove the service flap on the washer’s bottom right corner.
3. Place a towel under the drain pump opening to absorb any draining water.
4. Slowly twist and remove the drain pump cover.
5. Wipe the drain pump compartment with a paper towel to remove dirt and residue.
6. Make sure the drain pump impellers can spin easily by hand and are free of debris.
7. Replace the drain pump cover, twisting clockwise to secure.
8. Reattach and close the service panel door and restore the washer’s power and water supplies.

4. Defective Components

If the above measures fail to solve the problem, a Bosch washing machine not draining may be due to defective components. Drain pump malfunctions, such as a failed pump motor or damaged impellers can prevent the drain pump from expelling water. If the pump motor shows no continuity with multimeter testing or the impellers appear damaged, the pump requires replacement.

A faulty door lock can also affect draining, as the washer won’t receive the signal to begin spinning and draining if the lock doesn’t engage. If the lock appears damaged or fails multimeter testing with a lack of continuity, it must be replaced.
