Error E27 Dishwasher Bosch

What is the fault of the Bosch E27 error affecting your dishwasher?

Have you encountered the E27 error code on your Bosch dishwasher and don't know what it means or how to fix it? Don't worry, in this article, we'll explain everything you need to know about this issue and how you can resolve it easily, quickly, and safely.

The E27 error code on Bosch dishwashers indicates that there is a fault in the dishwasher's pressure sensor, which is responsible for measuring the amount of water entering and leaving the appliance. This sensor can fail for various reasons, such as a problem with the voltage of the power supply, an obstruction in the water inlet or outlet pipe, or a malfunction in the dishwasher's electronic board.

If this error is not resolved, the dishwasher may not function properly, leading to issues such as the water not heating, poor dishwashing performance, or leaks and overflows. Therefore, we'll provide you with the possible causes that may trigger the E27 error code on your dishwasher:

• A problem with the voltage of the power supply: If there is a surge or drop in voltage in the electrical network, the pressure sensor may detect incorrect pressure and display the E27 error. This can happen, for example, during a lightning storm, a general power supply failure, issues with your home wiring, or problems with the electrical outlet.
• An obstruction in the water inlet or outlet pipe: If there is any object blocking the water flow through the pipes, such as food residues, dirt, or a bent pipe, the pressure sensor may measure abnormal pressure and trigger the E27 error code. This can occur, for instance, due to improper dishwasher installation or a lack of maintenance.
• A malfunction in the electronic PCB of the dishwasher: If the electronic board controlling the operation of the pressure sensor is damaged or defective, it may send incorrect signals to the sensor, resulting in the E27 error code. This can happen, for example, due to a short circuit, overload, or a hit or fall of the dishwasher.

This fault can be somewhat complicated to solve, remember that you can always go to Bosch technical support to help you solve this problem with your dishwasher. However, we are going to leave you here the possible solutions that you can apply to find a solution to this error as soon as possible:

2. Check the voltage of the power supply to your dishwasher: The second step is to verify that the voltage of the power supply is appropriate for your dishwasher. Refer to the manufacturer's manual and ensure that your electrical supply is suitable for the specific model of your dishwasher. You can use a multimeter to measure the voltage at the electrical outlet where the dishwasher is connected and compare it with the value indicated on the appliance label. If there is a significant difference, you should contact your power company or an electrician to address the issue.
3. Clean and inspect the water inlet and outlet pipes of the dishwasher: The third step is to clean and inspect the water inlet and outlet pipes of the dishwasher. Disconnect the dishwasher from the power supply and turn off the water supply valve. Then, disconnect the pipes from the dishwasher and the drainage and check for any objects obstructing the water flow. Also, ensure that the pipes are not bent, broken, crushed, or cracked. If necessary, clean them with hot water and vinegar or replace them with new ones. You can also insert a wire from one end to unclog them in case of blockage or blow forcefully from one end.
4. Repeat all the previous steps if the problem persists: If after performing the three solutions above, the E27 error code continues to appear, you should repeat all the steps from the beginning to make sure you haven't missed any details.
