Error F34 in a Bosch washing machine

Error F34 in a Bosch washing machine If the Bosch automatic washing machine displays error code F34, the washing will not start. The program will not start because the washing machine door will remain open, therefore, it will not be possible to achieve a seal. Let's figure out what to do in this case, whether you can cope with the problem yourself.

Trying to reset the error

When you see a fault code on the display, you need to figure out what the symbol indicates. Error F34 on a typewriter Bosch signals problems with the sunroof locking device. The lock does not work, the door does not close.

In 20% of cases, this code occurs due to a short-term glitch in the program.

So, in one case out of five, repairs will not be required. Rebooting the system will help. To reset F34, you must:

turn off the washing machine;
set the programmer knob to the “Spin” mode;
wait a couple of seconds. A characteristic signal will be heard and an error code will be displayed on the screen;
hold down the arrow button (it is located near the display) and count to four;
sharply turn the program selector to the “Drain” mode (still holding down the button);
release the “Arrow” key and move the programmer to its original position (“Off”).

If after these manipulations the error is cleared and the washing fails to start, then the cause is a breakdown. You will have to check the locking device and replace it if necessary. Let's figure out how to do this.

Testing UBL

If error F34 appears on the display, you will have to check the UBL. You need to gain access to the lock to diagnose it. It is recommended to get to the mechanism on Bosch machines through the top. True, you will have to act by touch.You can take a different route - remove the outer clamp of the hatch cuff, tuck the edge of the rubber into the drum and remove the locking device.

The disadvantage of the second method is that there is a chance of damaging the door seal. The rubber band is responsible for the tightness of the system; its displacement can cause a leak. You should work carefully to minimize the risk of damage to the gasket.

Checking the blocker is quite simple:

familiarize yourself with the electrical diagram of the UBL, it is presented in the instructions;
turn on the multimeter, switch it to resistance measurement mode;
attach the tester probes to the contacts of the locking mechanism;
evaluate the value on the device display. If it is a three-digit number, then the device is working;
test the blocker for common contact. A one or zero on the multimeter screen will confirm the serviceability of the UBL.

Having identified a breakdown, you should not even try to repair the hatch locking device. It is much easier and cheaper to purchase a new element and install it on a Bosch washing machine.

When choosing an analogue of UBL, you need to focus on the model and serial number of the machine.

Replacing the locking device

To deal with error code F34, you will have to install a working blocker. You will need a minus screwdriver and an Allen key. Before starting work, you need to turn off the power to the machine, disconnect the equipment from the sewer, and turn off the water supply tap. The algorithm for dismantling the old device and installing a new device is as follows:

remove the cover of the washing machine by unscrewing the two bolts securing it;
tilt the washer body back so that the drum “moves away” from the front panel of the body;
holding the blocker from below, insert your other hand into the hole between the drum and the wall;
disconnect the UBL contacts;
using a hexagon, unscrew the bolts holding the locking mechanism;
remove element;
Reconnect a working locking device.

You can fix a machine that issues code F34 with your own hands. The main thing is to choose a suitable UBL and do the job carefully. It is also important to follow safety precautions.
