Washing machine shows E18 in display

3 checks to get your washing machine running again.

The E18 code that appears in the Bosch washing machine display means that there is no drainage of water. And maybe you also notice that there is water in the tank. Don’t worry this problem is solvable in many cases by your own. Reasons might be a blocked pump or kinked drain hose.

In various Bosch washing machines models, the error might be shown by different codes. F18 and d02 faults are the identical ones.

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

If such an error occurs, the first thing a user should do is to close the water supply so that no more water can flow in. Next, turn off the washing machine first with the button, and then pull out the main plug.

To find the cause and to check the pump you must drain the water away from the tank.

How to check the pump?

Note: To prevent unused detergent from flowing straight into the drain during the next wash: Pour 1 litre of water into compartment II and check the pump for leakage and the power of the pump, pour 1 litre of water into the detergent drawer.

Start the drain/empty programme.

Check for any leakage.

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

An E18 error can also be caused by a blocked or kinked drain hose.

First, look to see if the drain hose is bent or kinked, which may be blocking the water flow. If that is the case, simply straightening the hose may fix the problem. If the hose looks uncompromising, then disconnect it from the drain, unscrewing a clamp if necessary.

Follow the instructions in the video to check the drain hose.

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

After carrying out one or all of these actions, your washing machine should once again be correctly pumping and draining the water. If your washing machine is still not pumping out the water, it could be due to a defective pump.
