Error U1 Induction plaque Bosch

What is the fault of the U1 error Bosch affecting your induction cooktop?

If you have a Bosch induction cooktop, you may have encountered the U1 error code on your valuable appliance's display at some point. This error code indicates a problem with the electrical voltage powering your induction cooktop, which can hinder its proper functioning or even damage it.

The U1 error code can appear for various reasons, but all of them are related to incorrect electrical voltage, either due to excess or deficiency in the electrical supply. This can be caused by a failure in the electrical supply itself, voltage spikes, or inadequate voltage for your cooktop model.

There are several possible causes that can lead to incorrect electrical voltage in your Bosch induction cooktop, resulting in the U1 error code. Some of them include:

• Electrical supply failure: There may be outages, interruptions, or fluctuations in the power grid affecting the voltage reaching your home. This could be due to external causes such as storms, construction work, or faults, or internal issues like poor electrical wiring.
• Voltage spikes: Sudden and brief increases in electrical voltage can occur for various reasons, such as turning on or off other electrical appliances, lightning strikes, or transformer failures. Voltage spikes can damage the electronic components of your Bosch induction cooktop if not protected by a good regulator or voltage stabilizer.
• Inadequate or incorrect voltage: It may happen that the electrical voltage reaching your home is not suitable for your Bosch induction cooktop, either because it is higher or lower than the recommended voltage. This could be due to errors in the electrical installation, incorrect appliance settings, or incompatibility between the appliance voltage and the household voltage.

How to fix the U1 error on Bosch induction cooktop?

If you see error code U1 on your Bosch induction hob, don't worry. There are some possible solutions that you can try to solve the problem and get your appliance working again so you can cook your food properly:

1. Restart the induction cooktop to refresh the sensors: This is the simplest and quickest solution, involving turning off and on the appliance to reset and recalibrate the sensors. To do this, disconnect the induction cooktop from the electrical outlet for a few minutes and then reconnect it. Now, turn it on and check if the U1 error code has disappeared.
2. Check the electrical voltage with a multimeter: This solution requires a bit more technical knowledge, especially in electronics. It involves measuring the electrical voltage reaching the appliance with a multimeter. Disconnect the appliance plug and place the multimeter probes on the outlet terminals. Adjust the multimeter to the appropriate range and read the indicated value. If it differs from the manufacturer's recommendation, it indicates a problem with the electrical voltage.
3. Inspect the electrical installation and wiring in your home: Verify that the electrical installation and wiring are in good condition and meet an acceptable quality standard for your induction cooktop. You may need to contact an electrician to inspect your entire electrical installation, especially the part connected to your induction cooktop. If there is any fault in the wiring or its components such as outlets, fuses, connectors, etc., please ask the electrician to replace the defective or damaged elements with new ones.
4. Repeat all the previous steps and make sure to follow everything precisely if the problem persists: This solution involves going through all the previous steps again, following the instructions more carefully. Sometimes, the problem may not be resolved on the first attempt, and it is necessary to persist a bit more. If the U1 error code continues to appear after repeating all the steps, proceed to the next solution.
5. You will need to request a review of your induction cooktop from Bosch technical support: Call the phone number listed in the instruction manual or on the official Bosch website, and explain the issue you are having with the U1 error code. A specialized technician will contact you and provide guidance on how to resolve the problem, whether it involves sending your appliance to the service center or arranging for a home visit.

In summary, the U1 error code on your Bosch induction hob tells us that there is a problem with the electrical voltage that powers your appliance. Possible causes are a failure in the electrical supply, voltage spikes or inadequate or incorrect voltage. The possible solutions that you can apply to solve this failure, in a very summary way, would be the following:

• Restart the induction hob to refresh the sensors
• Check the electrical voltage with a multimeter
• Check the electrical installation and wiring
• Repeat all the previous steps and make sure to follow everything exactly if the problem persists
• You will have to request a review of your induction hob with Bosch technical support

We hope that this article has been useful to you and that you have been able to solve the U1 error code on your Bosch induction hob. This problem, which could be a failure in the electrical supply, we recommend that you address it immediately, because it could cause serious damage to your precious appliance and you will be left without being able to cook. Good luck and happy cooking!
