Bosch dishwasher error codes without display

Despite advances, most Russian families still use Bosch dishwashers without a display. This is inconvenient, not least because errors in a dishwasher without a display are difficult to identify without the official user manual or at least a handy cheat sheet. Let's take a closer look at the main error codes, how to identify them, and what they typically indicate.

Cipher display problem

No error codes can be recognized in Bosch equipment without a display if the “home assistant” is in operating mode. This is due to the fact that if any malfunction occurs in the machine, the “faucet” indicator will light up or blink. Therefore, the specific cause of the malfunction can only be determined in a special service mode. What should I do to access it?

• First, you need to unplug the dishwasher.
• Then turn on the equipment and start the service mode.
• Finally, it is necessary to conduct an accurate diagnosis to find out the error code and begin troubleshooting the problem.

It all sounds simple, but inexperienced users often encounter two problems. The first is that not everyone knows how to properly activate service mode on a Bosch dishwasher. The second is a lack of understanding of the error code among all the possible indicators on the dishwasher body. The situation is further exacerbated by the fact that service mode is activated differently on different models of Bosch dishwashers, which we'll discuss in the following sections.

Service and diagnostic system for the SHU series dishwasher

To accurately identify all errors in a dishwasher without a display, you must first enter service mode. First, we'll explain how to put your Bosch SHU43E/53E/66E appliance into special mode.

• Turn the wash program selector knob to six o'clock, that is, lower it vertically downwards.
• Press and hold the Start/Stop button and turn on the device using the power button.
• Press the Start/Stop button.

These steps will initiate service mode, in which the unit will begin flashing various lights. At this point, the user should not only identify the illuminated lights but also the order in which they appear, which will indicate error codes. Pay attention to the following lights:

• “Ready” – readiness light, “Ready”;
• "Circle" - sink light, "Brush", "Act";
• “Clean” — end of cycle light, “Clean”, “End”.

The set of errors may vary depending on the dishwasher model.

Now let's identify the error codes the machine is trying to communicate via active indicators during service mode. If the "Ready" and "Clean" lights are flashing, there are currently no errors, or the machine simply can't pinpoint the problem. If the "Ready" light is on and the "Clean" light is flashing actively, the appliance is experiencing problems heating the water.

If the "Ready" and "Clean" lights are flashing while the "Circle" light is constantly on, your Bosch dishwasher is for some reason unable to fill with water for a cycle. Finally, if the "Clean" light is flashing while the "Ready" light is constantly on, it's worth inspecting the thermostat for damage.

SHV series dishwashers

Now let's explore the process of searching for error codes in Bosch SHV46C, SL84A, and SHX33A/43E/46A-B home appliances. Entering service mode on this equipment seems straightforward.

• Press and hold the “Regular Wash” and “Delicate/Econo” or “Rinse&Hold” buttons.
• Start the Bosch dishwasher using the power button.
• If the light next to “Regular Wash” is on while “Delicate/Econo” or “Rinse&Hold” are actively flashing, then you have entered service mode.
• Now you can select a test program using the “Regular Wash” button, after which “Delicate/Econo” or “Rinse&Hold” will start to light up.
• All that remains is to press “Delicate/Econo” or “Rinse&Hold” to start the diagnostics.

During the test, pay attention to the "Power Scrub," "Regular Wash," "Delicate/Econo," or "Rinse & Hold" indicators. If the "Delicate/Econo" or "Rinse & Hold" indicator lights up, there's a problem with the water heating. When the "Regular Wash" indicator lights up continuously, the Bosch machine is alerting the user to a faulty temperature sensor. If the "Regular Wash" indicator lights up along with the "Delicate/Econo" or "Rinse & Hold" indicators, the problem lies in the components responsible for filling the water. Finally, if the "Power Scrub" and "Regular Wash" indicators light up, the water turbidity sensor is most likely faulty.

In older Bosch dishwasher models, the manufacturer didn't include many error codes, so identifying the underlying problem is usually easy. However, if the appliance's simple indicators don't reveal the problem, it's worth calling a service center technician for a thorough diagnosis and immediate repair.
