How to Fix Bosch Washing Machine E18 Error Code? Simple Steps to Fix

What is Bosch Washing Machine E18 Error Code?

If you have a Bosch washing machine and see the E18 error code displayed, it means that the water in the machine is not draining. This issue can often be resolved on your own, as it is usually caused by a blocked pump or kinked drain hose. Additionally, you may notice that there is still water in the washing machine’s tank. It’s important to note that the E18 error code may be displayed as F18 or d02 on different models of Bosch washing machines. If you see any of these codes, it’s time to perform three checks to get your machine running again:

Check the pump for any obstructions: The first thing you should do is check the pump for any blockages that may be preventing water from draining. You can usually access the pump by removing the panel at the front or back of the machine. Once you locate the pump, remove any debris or blockages that you find.

Check the drain hose: A kinked or blocked drain hose can also cause the E18 error code. Check the hose for any bends, twists, or obstructions, and straighten it out if necessary. You may need to remove the hose from the machine to do this.

Check the drain filter: Many washing machines have a filter that catches debris and prevents it from entering the pump. If this filter is clogged, it can cause water to back up and prevent proper drainage. Check your machine’s manual for instructions on how to locate and clean the filter.

After performing these checks, your washing machine should be able to pump and drain water correctly again. However, if the problem persists, it may be due to a defective pump and you should contact a professional for further assistance.

How to Fix Bosch Washing Machine E18 Error Code?

1. Start by drain the water away and check the pump

In case of such an error, the initial step for the user is to shut off the water supply to prevent further water flow. Subsequently, the washing machine must be switched off using the button and the main plug must be unplugged. The cause of the error and the pump must be checked by draining the water from the tank.

To remove the water that remains in the machine:

• Caution should be exercised when touching the hot washing water, as it can cause scalds. Therefore, allow the water to cool down before proceeding. 

• Open the service flap and take the drain hose out of the holder. 

• Remove the sealing cap and drain the water into a container suitable for the purpose.

• After that, put the sealing cap back in place and press it firmly. 

• Finally, drain all the water using the drainage hose.

Here are the steps to check the pump:

• Unscrew the pump cover carefully, as any remaining water may leak out.

• Take out the pump cover.

• Clean the interior of any residues and also clean the inside, the pump cover thread, and the pump housing.

• Ensure that the impeller in the drain pump can rotate smoothly.

• Put the pump cover back on and screw it back firmly, making sure that the grip is vertical.

• Close the service flap.

It is important to note that unused detergent may flow straight into the drain during the next wash if it is not addressed. To prevent this from happening, you should pour 1 litre of water into compartment II and check the pump for any leakage or issues with its power. Additionally, pour 1 litre of water into the detergent drawer to check for any leaks. After performing these checks, start the drain/empty program to ensure that the pump is working correctly and that all the water has been drained from the machine. It is crucial to check for any leakage during this process, as it could indicate a problem with the machine that needs to be addressed. By taking these steps, you can ensure that your washing machine is working efficiently and that you are not wasting any detergent or water during the washing process.

2. Check the drainage whether it is kinked or blocked by foreign

A potential reason for an E18 error is an obstructed or twisted drain hose. It is essential to examine the drain hose first if this error occurs. Check if the hose is bent or twisted, which could obstruct the flow of water. If the hose seems to be the issue, try to straighten it. Straightening the hose might solve the problem. However, if the hose is still obstructed, it is necessary to disconnect it from the drain, and in some cases, unscrew a clamp that may be holding it in place.

3. Is the washing machine still showing E:18 in the display and is not draining the water?

Once you have performed any of the suggested actions mentioned earlier, such as checking for blockages or kinks in the drain hose, your washing machine should be able to pump and drain water correctly. However, if the issue persists, it could indicate a faulty pump. In this case, it is advisable to seek professional help to repair or replace the pump. It’s important to avoid using the washing machine until the issue is resolved to prevent any further damage.

Cause of Bosch Washing Machine E18 Error Code

The Bosch washing machine manual provides a concise explanation for the E18 error code, which indicates a failure to drain water from the machine’s tank. Users may notice that there is still water in the tank, and the machine has not attempted to initiate the draining process. In instances where the washing machine lacks a display screen, users may identify the error through the spin speed indicators on the control panel. When there is no drainage, the 1000 and 600 spin speed indicators light up.

Various factors could cause the washing machine tank to fail to drain water, including incorrect drain hose connection, bent or clamped water drain hose, blockage in the drainage system (filter, nozzles, pumps), pump failure, malfunctioning water level sensor, and module malfunction. Here are a few more possible reasons for the E18 error code:

• A clogged drain filter

• A faulty pressure switch or pressure sensor

• A malfunctioning control board

• A damaged or worn-out pump motor

• A malfunctioning inlet valve that prevents water from entering the washing machine

It’s important to note that while these are potential causes, it’s always best to refer to the manufacturer’s instructions or consult a professional if you’re unsure about how to diagnose or fix the issue.
