Bauknecht dishwasher error f4

What is the F4 Bauknecht error affecting your dishwasher?

If your Bauknecht dishwasher is indicating an F4 or F04 error, then you are in the right place to find a solution. The F4 error code on Bauknecht dishwashers signals that you have a problem with your dishwasher's drainage system.

The drainage system consists of several components for its proper functioning, so it could be any one of these or several at once causing this fault.

Among the possible causes that can make this type of error appear on your dishwasher are the following:

• The filter is dirty or blocked by foreign objects or food residues: This device prevents food remnants from passing through the drainage system, causing bigger issues in the future. If the filter is blocked, then the water won't be able to flow freely and will become stagnant.
• The drain/drainage tube is blocked or obstructed: A pronounced bend in the pipe could also block your dishwasher's drainage. If the tube is blocked, bent, or obstructed, you have an issue that you'll need to address as soon as possible.
• A blocked or faulty drain/drainage pump: If the pump is faulty, it won't be able to pump the water out through the drainage system. And if this same pump is blocked, it also won't be able to remove the water, causing it to accumulate in the system, triggering the F4 error code on the dishwasher.

How to fix the F4 error on the Bauknecht dishwasher?

To find a solution to this problem, follow the steps we outline below. The F4 error code on a Bauknecht dishwasher is an issue that can be fully repairable, so there's not too much to worry about:

1. Restarting the dishwasher might fix the issue: Turn off the dishwasher and unplug it from the power source for a few minutes. Sometimes, a system restart can fix the problem by resetting the sensors. Reconnect and turn on the dishwasher to see if the error has disappeared.
2. Clean the dishwasher's filter: Remove the appliance's filter and clean it thoroughly. Ensure all food remnants are removed, and if it looks like new, you're good. If the filter is broken, check the other parts of the drainage system because food and waste might have lodged in your dishwasher. If the filter is broken, make sure to replace it; fortunately, this part isn't expensive at all.
3. Check the drain and/or outlet hose of your dishwasher: Ensure the hose isn't bent, squashed by furniture or another appliance, broken, or obstructed. If needed, straighten the hose or reposition it to help it drain any accumulated water. If possible, dismantle this hose and clean it thoroughly with water, soap, and a bit of vinegar.
4. Inspect the drainage pump of the dishwasher: Remove the bottom cover of the dishwasher, granting complete access to the drainage pump. Examine it closely to ensure it's not blocked by food residues, plastic pieces, or even bones. Conduct preventive maintenance, but if the pump is defective, you'll need to replace it with a new one.
5. Review everything again meticulously: If after all these checks you still have the same problem, it wouldn't hurt to review everything again. Go through everything mentioned above and ensure you've followed every step precisely. Don't overlook anything or leave anything to chance; you need to solve this problem if you want to keep using your Bauknecht dishwasher.
6. Consult Bauknecht's technical support: Sometimes it's best to leave problems to the experts. Who better than Bauknecht's own technical support? Call them and schedule an appointment; they'll likely help you fix the issue quickly and effectively. They will inspect the dishwasher and provide an appropriate solution.
