We’ll go over some of the reasons why your Bosch washer isn’t draining and provide you with some DIY solutions to correct it!
What To Do When Your Bosch Washer Won’t Drain
If your Bosch washer won’t drain water after a load, it’s time to take some action! Depending on the severity of the issue, there are a few things you can try to fix it. Follow these steps and see if you can get your washer draining properly again.
1. Drain the Washer Manually
The first thing you’ll want to do is try to drain the washer manually, if water is left too long you may experience a smell from your washer. If there’s a lot of water in the tub, it can be tricky to do this without making a mess. You’ll need to locate the drain hose and disconnect it from the washer, this is usually under the flap on the bottom right corner.
Once it’s disconnected, place a shallow container under the opening and remove the drain plug. Then let the water start to drain into the container.
2. Check the Drain Hose For Kinks or Blockages
When the water is draining, you’ll want to check the hose for any blockages. If there’s a clog in the hose, it can prevent the water from draining properly. You can use tweezers or a plumber’s snake to try and remove the clog. If you can’t clear it, you may need to replace the hose.
You will also want to check and make sure the hose isn’t kinked or bent in any way before you reconnect it. See if that fixes your Bosch washer not draining problem, if not keep reading.
3. Clean the Drain Pump

If the drain hose is clear and your washer still won’t drain, the next step is to check the drain pump. Over time, lint and other debris can build up and cause a blockage. To clean the drain pump follow these steps:
- Unplug the washer
- Place a towel down to catch any water
- Access the drain pump by removing the lower panel
- Take the drain pump cover off
- Remove any debris that you see
- Check that the impellers can spin by hand and are free of dirt
- Put everything back together and plug the washer in again
4. Check for Part Failure
Once you’ve completed these steps, run a test load of laundry and see if the washer is draining properly. If not, there’s a good chance one of your parts has failed. The most common culprits are the drain pump, the door seal, or the pressure switch.
