Error F16 in the Bosch washing machine

error F16 on CM BoschError F16, which is embedded in the self-diagnosis system on the Bosch washing machine, is one of the most obvious. Even without any decryption, the user quickly understands what caused it, however, to solve the problem, this knowledge is not enough, you need to know the nature of the breakdown that triggered the F16 code, and most importantly, understand how to fix it. We will talk about this in this article.

Decryption and reasons for the appearance of the code

If an error with alphanumeric code F16 appears on the display or control panel of your Bosch washing machine, be aware that the "home assistant" had problems with locking the hatch door. In general, you yourself will understand this when you close the hatch, start the washing program, and the machine will immediately give F16.

This error usually appears immediately after choosing a washing program. It is extremely rare that this code pops up in the middle or at the end of the wash.

If your Bosch model has a display, then there are no problems at all. You see the code, quickly decrypt it, determine the list of possible malfunctions that gave rise to it and begin to search for a specific breakdown. It's a completely different matter if you have a machine without a display. Another obstacle appears. First you need to somehow recognize this error, and only then perform the above actions.

The picture above shows the control panel of a Bosch brand washing machine without a display, which generated an F16 error. As you can see, the lights on the control panel do not light, only the LED opposite the number 1000 blinks. On models in which spin is slower, the error F16 can be indicated by the light opposite the number 800. What can the F16 code appear from?

  • The hatch lock does not work or is de-energized.
  • Faulty sunroof locking mechanism.
  • Something is preventing you from closing the hatch.
  • Broken wiring or burnt contacts between the UBL and the control module.
  • Faulty control module.

Perhaps the reason is UBL?

UBL for washing BoschSo, without delaying, we will begin to check the locking device of the hatch of the washing machine. Disconnect the washing machine to avoid electric shock. We open the hatch door as wide as possible. Inspect the hatch locking mechanism. It is very possible that the UBL has nothing to do with it, but the locking mechanism, which consists of a special hook and spring, is to blame. Check if the spring is intact and the hook of the lock is not shifted to the side.

If everything is in order with the locking mechanism of the hatch, it is necessary to start the UBL check. To the left of the hatch there is a small hole with two fasteners on the sides, they need to be unscrewed. Having unscrewed the screws, we tilt the Bosch washing machine a little back, and then with our fingers pushing the cuff of the hatch, we put our hand in, feeling for the UBL. Then comes the crucial moment, since we need to use our fingers to find the chip with the wires connected to the UBL and carefully disconnect it. If you succeed, feel free to get UBL.

In the event that you cannot disconnect the wiring from the UBL in this position, you will have to remove the cuff or even the front wall of the Bosch machine and only then disconnect the UBL, and this is unnecessary work.

Next, we test UBL with a multimeter. If the device is malfunctioning, we purchase a new, original one, and then put it in its place, not forgetting to connect the power wiring.

Control module and wiring

If the sunroof locking device works fine, but the washing machine still issues the F16 code, you must test the power wiring that goes from the control module to the UBL. To do this, you need to have relatively free access to the UBL wiring, and this can be done only by removing the hatch gum. About, how to remove the cuff of the hatch of the washing machine, is described in sufficient detail in the same article, to focus on this separately, we will not.

Having access to the wiring, we check it for a break. At the same time, you need to test and clean the contacts.If, in this case, the problem has not manifested itself, most likely the electronic module is to blame for the F16 error. Do not check and repair the control module yourself if you do not have the appropriate knowledge and qualifications. Entrust this matter to a specialist in order to avoid additional waste of money and time.

In conclusion, we note that if the washing machine, which has served faithfully for many years, suddenly gives an error code F16, you should immediately start looking for the problem. The one that caused her. How to do this, and how to fix the washing machine later, is described in the publication. Have a good repair!
