Resetting an error on a Bosch dishwasher

Various error codes in dishwashers can occur not only due to breakdowns, but also after a one-time failure. Resetting an error on a Bosch dishwasher is important in a situation where the fault has been fixed, or you are absolutely sure that a one-time failure is to blame. If it is still unknown what exactly caused the error, then a reset should not be performed under any circumstances, as it can seriously damage the equipment. We will tell you in detail how to correctly reset errors in dishwashers.

Why is code reset necessary?

The automatic diagnostic system in dishwashers is becoming smarter and smarter every day. It often seems to users that the technology is capable of not only diagnosing and displaying the error code itself, but also turning it off when the problem is solved. Unfortunately, usually, even after replacing a faulty part, the machine does not immediately determine that the problem has been fixed, so it needs to reset the error. This is why the error will continue to appear on the display, blocking the normal operation of the dishwasher until the user resets it manually. Most often this situation occurs due to the following problems:

• one-time failure of the PMM control board;
• error of the current working cycle and its subsequent stop;
• clogged garbage filters or hoses;
• improperly installed water supply or drain hose;
• interruptions in the water supply to the machine;
• leak;
• clog in the sewer.

A common situation is when the dishwasher user is confident that he correctly identified the malfunction and fixed it, and therefore cannot understand why the error does not disappear.It can be very easy to make a mistake in finding and localizing a problem, given the huge number of possible causes of a malfunction. Therefore, you should never run an error reset unless you are sure that the real cause has actually been eliminated. If there is even the slightest doubt, it is better to call a service center specialist so that he can carry out an accurate diagnosis and repair.

The usual way to reset the code

When the Bosch dishwasher did not complete the wash, but stopped working, displaying an error on the display, you need to open the washing chamber door slightly and leave the equipment like that for a few minutes. Then you need, without turning off the equipment, hold down the first two keys to the left of the display for three seconds - these two buttons will launch the service mode.

The buttons may perform different functions depending on the dishwasher model, but pressing them simultaneously will launch the Bosch service mode.

When you have a less modern dishwasher, for example, Bosch SHU43E/53E/66E, the service function is activated differently. With the dishwasher turned off, you must first turn the program selector to the “six o’clock” position, then hold down the “Start/Stop” button and turn on the “home assistant” with the power button.

If you have modern equipment from Bosch, then resetting errors that are stored in the equipment’s memory is done by pressing the first and third buttons to the left of the display. The keys must be pressed for three seconds, after which the dishwasher will reset the fault code.

Dishwashers SHU43E/53E/66E are even easier to maintain. You must first go into service mode, and then hold down the “Start/Stop” key for about three seconds so that the error disappears.

Zeroing when the PMM is completely de-energized

Lastly, we will look at an unreliable method of resetting errors in a dishwasher, which can cause damage to the PMM control board. Because of this, use it only in a situation where nothing else helps. To reset the error in this way, you need to simultaneously press the power button and disconnect the power cord from the network.

Call someone for help if the outlet is too far from the dishwasher to prevent you from doing the steps described at the same time.

The bottom line is that when the “home assistant” is turned off, you need to press the power button, wait for the sound signal and immediately turn off the power to the equipment. This helps because immediately after activating the dishwasher, the manager of the model conducts an instant test of all key components of the system, which lasts a matter of seconds.

And if you turn off the dishwasher at this moment, all stored fault codes will also be reset. It is important to remember that such an action does not always help, because it is very important to synchronously turn on and de-energize the equipment so that the fault code is reset.
