• An error code related to draining appears on the display panel (e.g., E:22, F:18, or similar).

• The washing machine won’t start a new cycle because it detects standing water.

How to Fix bosch washing machine water not draining Step-by-Step Guide

1. Unplug the Washing Machine: For your safety, always disconnect the power before attempting any repairs.
2. Check the Drain Hose: Inspect the drain hose for kinks, bends, or obstructions. Straighten any kinks and ensure the hose isn’t pinched behind the machine.
3. Inspect the Drain Hose Connection: Ensure the drain hose is securely connected to both the washing machine and the drainpipe.
4. Check the Drain Pipe: Ensure that the drain pipe is not blocked. If possible, run water down the pipe to see if it drains freely.
5. Locate the Drain Pump Filter: This is usually located at the bottom front of the machine behind a small access panel. Refer to your user manual for the exact location.
6. Prepare for Water Spillage: Place a shallow pan or towel beneath the access panel, as some water will likely spill out when you remove the filter.
7. Remove the Drain Pump Filter: Carefully unscrew and remove the filter. It may be necessary to turn it counter-clockwise.
8. Clean the Drain Pump Filter: Thoroughly clean the filter under running water, removing any lint, hair, coins, or other debris.
9. Inspect the Drain Pump Housing: Shine a flashlight into the drain pump housing and check for any obstructions.
10. Reinstall the Drain Pump Filter: Securely screw the filter back into place. Make sure it is fully tightened.
11. Check for Air Lock: Gently wiggle the drain hose where it enters the drain pipe to try and dislodge any potential air lock.
12. Run a Test Cycle: Plug the washing machine back in and run a short wash cycle (or a drain/spin cycle) to see if the problem is resolved.
13. Check Drain Hose Height: Verify the height of the drain hose follows your user manual recommendation. It’s often between 24 and 36 inches (60-90cm) above the floor.
14. Try a different detergent: If using too much detergent or the wrong type, reduce the amount or switch to a low-sudsing detergent.

Fix the Issue Without Buying Parts

Many drain issues can be resolved without buying new parts:

• Reset the Machine: Turn off the machine, unplug it for 5 minutes, then plug it back in and try a drain/spin cycle.
• Clean the Drum: Run an empty washing machine cycle with a washing machine cleaner to clear out any build-up that might affect draining.
• Proper Detergent Usage: Use only the recommended amount of high-efficiency (HE) detergent.
• Inspect and Maintain Hoses: Regularly check hoses for kinks or damage.

When Replacement Might Be Necessary

If the steps above don’t solve the problem, you might need to replace a part. Common culprits include:

• Drain Pump: If the pump is making a loud noise or isn’t working at all, it likely needs replacement. (Estimated cost: $50-$150 USD).
• Drain Hose: If the hose is cracked or damaged, replace it. (Estimated cost: $15-$30 USD).
• Control Board: This is a less common issue but if the board is faulty, it may require replacement. (Estimated cost: $150-$300 USD). Seek professional help for diagnosis and replacement.
