4 Reasons Why a Bosch Washer Won’t Drain
There are a few common issues that can cause a Bosch washing machine not to drain water:
- Clogged or blocked drain pump filter: This filter catches coins, buttons, hair, and other debris. Over time, it can get clogged and prevent proper drainage.
- Drain hose is kinked or clogged: The drain hose can get kinked behind the washer. Or it may have soap buildup or other debris clogging it.
- Bad drain pump: The pump that pushes the water out could be worn out or defective.
- Clogged drain pipe: If your drain pipe going to the standpipe or wall drain gets clogged, it will back up the washer.
Apart from draining, another common problem many users face is their Bosch washer won’t spin properly.
Troubleshooting Bosch Washer Not Draining?
You’ll want to find the source of the problem. From obstructed hoses to drain pump issues, several factors could be at play when you’re trying to fix a Bosch washer draining problem.
Let’s pinpoint these issues and find some practical solutions.
1. How to manually Drain Water from Bosch Washer?
Encountering a Bosch washer full of water can stop you in your tracks. But fear not; the solution might be simpler than you think.
Before any troubleshooting, you need to drain the Bosch washing machine manually.
Here’s the straightforward process to manually evacuate water when your Bosch washing machine won’t drain.
Begin by cutting off the washer’s power and water supply, ensuring safety first. Locate the service flap, which you’ll usually find in the bottom right corner of the unit.
Prep the area with a shallow container to catch the unwanted water. Gently unclip the drainage hose, allow the water to empty into the container, and then re-secure the hose.
Once you’ve handled this step, restore the power and water supply, and your washer should be set for a proper drainage test.
2. Run a Drain Test
Many Bosch washing machines have a built-in drain test mode that allows you to run the drain pump for an extended time.
This can help clear out any residual clogs and get the machine draining properly again.
To run the test, first make sure the washer tub is empty. Then, enter the service or diagnostics menu.
On many models, you press the “Spin” and “Rinse” buttons simultaneously for 3-5 seconds to access this menu.
Once in the menu, select the “Drain” or “Pump Test” option. The washer will now activate the drain pump for 1-2 minutes.
Listen closely to hear if the pump sounds normal or if you notice any obstructions.
Let the drain test run full-time to allow any small blockages to be cleared out. The extended run time lets the pump work harder to push out any debris or buildup.
Check the water level after the test completes – water should have drained out completely if the test was successful.
If the tub still has water in it after the drain test, there is likely a clog or issue that needs further investigation.
3. Clogged Drain Pump Filter
The drain pump filter is one of the most common culprits when a Bosch washer won’t drain properly.
This filter is located at the bottom of the washer and catches all kinds of debris like dirt, lint, and hair before it goes down the drain hose.
Over time, this filter can get extremely clogged and prevent water from draining out of the tub.
To check this filter, first remove any remaining water from the tub using a sponge and bucket. Locate the access panel on the front bottom of the washer.
This may have a small door or need to be unscrewed. Pull out the drain pump filter and inspect it.
If it’s packed with gunk, simply remove all the debris – dirt, lint, hair, strings – until clean. You may need to rinse it off to get rid of detergent buildup.
Reinsert the drain pump filter once it is clean. Ensure it clicks firmly back into place and the access panel is securely replaced.
Many times, this simple cleaning of the filter is all that is needed to get a Bosch washer draining properly again.
The pump will work much more efficiently without fighting all that trapped debris.
4. Blocked Drain Hose
A blocked or kinked drain hose is another prevalent issue that can halt your washer’s drainage.
To remedy this, disconnect the power and move your washer to reach the hose comfortably.
With the help of a screwdriver, loosen the clamps, secure the hose, and conduct a thorough inspection.
Any twists causing kinks should be straightened, and if you encounter blockages, gently remove them.
Upon clearing the hose, fit it again, ensure it’s snug and secure, power on your Bosch washer, and check for smooth water flow.
5. Drain Pump Malfunction
When troubleshooting a Bosch washer, you might find the drain pump clogged with lint, coins, or other random items from pockets that forgot to empty before the wash.
To tackle this, power off your washer and lay down towels to catch any drips. Unscrew the pump cover with care and inspect for obstructions.
If you spot debris, remove it delicately, ensuring you don’t damage the pump’s impellers. A clear path for the impellers is essential for optimal function.
Once cleared and confirmed, reassemble the cover, power up your washer, and observe if the problem has been resolved.
6. Broken Bosch Washer Parts
At times, the problem is more complex, and part failures like a faulty lid switch assembly or a defunct pump can be to blame for the draining dilemma in your Bosch washer.
Use a multimeter to check the continuity of these parts. If you find a lack of continuity, the faulty part will need replacing.
Considering the intricacy of this task, it might be wise to enlist a professional.
They can ensure the replacement is handled correctly and your washer blemish is returned to its full functionality.
When your Bosch washer doesn’t drain, it can put a wrench in your laundry day.
But before you call the repair shop, try a few DIY troubleshooting steps. In many cases, the fix may be as simple as clearing a clogged filter or hose.
Run a drain test to diagnose where the drainage problem lies. Removing debris, kinks, and obstructions yourself could get your washer draining properly again.
If replacing parts is necessary, take it as an opportunity to learn about your appliance.
With some perseverance and targeted troubleshooting, you can conquer the Bosch washing machine not draining problem.
