Error E18 Dishwasher Bosch

What is the failure of error E18 Bosch affecting your dishwasher?

If you have a Bosch dishwasher and suddenly the E18 error code appears on the screen, there's no need to panic or feel bad. This code indicates that there is a problem with the water supply, so it's relatively simple to resolve.

This issue can stem from various causes. Today, we want to explain what this error means, what its possible causes are, and how you can resolve it in the best possible way without complications.

The E18 error code signifies that the dishwasher is not receiving enough water or that the water level sensor has been damaged for some reason. This can lead to the dishwasher not functioning properly or stopping in the middle of the wash cycle. Water is essential for the dishwasher to clean the dishes, so it's important to address this issue as soon as possible.

The possible causes that can trigger the E18 error code in your Bosch dishwasher are as follows:

• The dishwasher filters are dirty or clogged: Filters are responsible for trapping impurities and food residues in the water. If they are dirty, they can prevent water from circulating properly through the dishwasher.
• The dishwasher hoses are bent, crushed, or blocked: Hoses transport water from the water source to the dishwasher and vice versa. If they are bent, crushed, or blocked, they can reduce water flow or pressure.
• Insufficient water flow or pressure: Water flow and pressure depend on the water supply network and the faucet to which the dishwasher is connected. If the flow or pressure is insufficient, the dishwasher will not receive enough water to operate correctly.
• The water level sensor is defective: The water level sensor measures the amount of water in the dishwasher and sends a signal to the control panel. If the sensor is defective, it can send an erroneous signal or no signal at all, leading the dishwasher to display the E18 error code.

How to fix error E18 on Bosch dishwasher?

Now let's look at the possible solutions that you can apply to fix the E18 error code on your dishwasher. Some of these solutions are so simple that you don't even have to open the dishwasher, so you can try to fix this fault yourself:

1. Restart the dishwasher to reset the sensors: Sometimes, the E18 error code can be a momentary glitch in the dishwasher's electronic system. To resolve it, you can try restarting the dishwasher by unplugging it from the power source for a few minutes and then reconnecting it. Now, turn it on and check if the error has disappeared.
2. Check and adjust the water flow or pressure: To check water flow or pressure, open the faucet to which the dishwasher is connected and see if enough water comes out forcefully. If not, you can try cleaning the faucet filter or call a plumber to inspect the water supply network in your home.
3. Clean or replace the dishwasher filters: To clean the filters, remove them from the dishwasher and rinse them with warm water using a brush with soft bristles to avoid damage. If the filters are heavily damaged, you can purchase new ones and replace them.
4. Inspect, replace, and/or adjust dishwasher hoses: To inspect the hoses, disconnect the dishwasher from the water supply and check for any hoses that are bent, crushed, or broken. You also need to check if they are blocked because clean water can sometimes carry impurities that accumulate inside the hose. Apply the necessary corrections, and if possible, replace the hose with a new one along with the necessary valves and seals for its operation.
5. Replace the dishwasher's water level sensor or perform maintenance: Locate the sensor in your dishwasher, disconnect it, and carefully remove it. Clean it with a damp cloth, and if you have electronic cleaner, you can use it as well. Sometimes, excess foam can cause these sensors to malfunction, so remove any soap residue or sulfate if present. Once it's dry, place the sensor back in its place, connect it, and turn on your dishwasher.
6. Repeat all the above steps if the problem persists: If, after trying all the solutions mentioned above, the dishwasher still displays the E18 error code, there may be a more serious issue that requires a deeper inspection of the dishwasher. If so, it's advisable to double-check everything mentioned earlier.
7. Seek Bosch technical support to solve the problem: If none of the above solutions work, it is highly recommended to contact Bosch's technical support for a qualified professional to inspect and repair your dishwasher. You can call the customer service phone number or request an appointment online on the Bosch website.

In summary, the E18 error code indicates that there is a problem with the water supply to the Bosch dishwasher.
