Bosch washing machine detected a problem and issued an F34 error on the display. The washing program does not start, and the hatch door does not lock.
In this case, the decoding of the error code F 34 sounds like this: the washing door is not closed, there is no lock lock. Let's figure out what this means and how to fix the situation.
What to do to fix the problem
According to safety requirements, washing begins only after closing the hatch. And this does not happen immediately after the door is slammed. There is also an electronic lock (UBL) that locks the door, and then sends a signal to the control module to start.
Therefore, the malfunction can be mechanical and electronic in nature.
If the Bosch washer shows error 34 on the display, do this: reboot the system to clear error F34. What does this mean: Unplug the plug from the outlet, wait 15-20 minutes.
Look at the display after switching on: if the malfunction code is on, it means that the error did not work.
How to fix the problem in this case? It is required to check the internal components and parts of SM Bosch.
What the error means: troubleshooting
To understand why the Bosch washing machine gives an error code F 34, you need to be careful about the signs of a breakdown.
Mechanical malfunctions
As a result of prolonged use or careless handling, mechanical parts fail. What to do:
- If you are trying to close the door, but something is in the way, inspect the tab-lock: it happens that it moves. To solve the problem, you need to disassemble the handle and replace the pulley that holds the tongue.
- When the hinges holding the hatch warp, the latch does not reach the lock hole. The same thing happens when the Bosch machine is improperly installed. If her legs are uneven, the hatch may be skewed. You need to place the washer on a flat surface or tighten the side loops.
- The hatch closes as expected, but the locking mechanism does not click. The guide is probably worn out, especially if it is plastic. To install a new part, you need to disassemble the door.
Let's look at how to properly disassemble a door to replace elements:
- Remove the hatch from the Bosch machine by unscrewing the two mounting screws.
- Remove the bolts around the perimeter of the door.
- Press the latches along the edges and separate the door into two parts.
- Remove the glass.
- Remove the pin to disengage the handle.
If these steps did not help to clear the error, and the code F34 is displayed again, proceed to the next step.
Electronic issues
A characteristic sign of failure of the electronics is the lack of starting the program. The sunroof is closed normally, but washing does not start, error code F 34 lights up on the display.
- UBL. The hatch lock device is powered by electrical impulses. Bimetal plates heat up and expand, affecting the lever. Often the cause of a UBL problem is voltage drops or natural wear. In this case, it is necessary to replace the lock.
- Carefully inspect the UBL. The hole may have clogged with small debris that needs to be removed.
- A faulty module may serve as an error. Before taking measures for replacement or repair, conduct a thorough diagnosis of all elements of the board. The check can be performed by a Bosch machine self-test or by a multimeter.
Remember to inspect the loop of wires and connections from the control module. It happens that from constant shaking, the wires are frayed.
