E18, F18 Error in a Bosch washing machine

Error code E18 or F18 means that the Bosch washing machine cannot drain the water after the wash cycle is completed. In other words, it is noticeable that the program has ended in time, but the tank is still filled with water. This means that for some reason the drain mechanism did not start, and you can't just open the door to get the laundry. If the machine does not have a display, then the spin indicators will flash or light up to indicate that the drain is not draining.

If this happens, you must immediately turn off the water supply and turn off the unit itself by pressing the button. You also need to remove the plug from the socket. Then, to diagnose and understand the causes of the malfunction, you need to drain all the water from the tank. To do this, you can pull out the drain hose or drain filter. True, the second method threatens with flooding.

How to eliminate

If the error code E18 or F18 is visible, it is not necessary to immediately call the service center. Often the problem is easy to fix on your own, it is only important to understand the cause. The most common:

• Clogged drain filter. It protects the pump from lint, debris, foreign objects. You can also clean it up on your own. How to do this is written in the instructions.
• Drain hose kink. It is enough just to straighten it, and the problem will disappear.
• Sewer blockage. E18 errors are common with washers connected to a sewer siphon. Checking the problem is easy - just get the hose from the sewer and insert it into the sink. If the drain is working, then you need to clean the sewer.

Rarely, but it happens that the water does not drain due to a board failure. Try disconnecting the machine from the network for 10-15 minutes and then start it again.
