Bosch F34 Error Code

[Alfie Overacre]

Welcometo the guide to Bosch Dishwasher Error Codes. This comprehensive list is designed to provide you with detailed explanations and solutions for a wide range of error codes that your Bosch dishwasher might display. Running into problems with your dishwasher can be frustrating, but we're here to help you understand what these codes mean and how to troubleshoot them effectively.

Dishwashers are used on a regular basis which means that limescale can build up quickly, especially in hard water areas. To help your dishwasher work efficiently and effectively, and to ensure your dishes come out clean, regular descaling is important.

Remove and wash the filter under running water with mild soap and a soft brush to remove debris then reinstall. You can find the full instructions on how to clean your dishwasher filter here. To learn more, view our 'How to Clean Your Dishwasher Filter' video on our How-to Video page

2. The drain pump may be blocked. The pump is located at the bottom of the dishwasher underneath the filter. First, remove the filter completely to reveal the drain pump cover. Next, pry off the pump cover with a spoon until it clicks. Grip the cover and pull upward until you feel resistance. Then pull forward to remove the cover completely. Check the pump and remove any debris and standing water with a sponge. Use caution as some debris may be sharp. If needed, review your owner's manual for more specific instructions.

1. Check the inlet hose and make sure it isn't kinked or damaged.

2. Make sure the water supply is turned on. The water flow rate should be 10 l/min.

Outside of error codes, there are additional symbols on Bosch dishwashers that indicate your appliance is experiencing an issue that needs attention. Here are some tips on troubleshooting error symbols you might encounter on your appliance:

If your Bosch dishwasher is beeping, there are multiple possible causes, and these issues are usually signaled by the number of beeps. Some common causes of your dishwasher beeping are the end of cycle notification, an improperly closed door, or drainage issues. Oftentimes, these beeps will be accompanied by another error code in this guide.

If the beeping persists and you're unable to resolve the issue using the steps above, it might be time to seek help from a professional. Bosch provides support and can recommend certified technicians. Please contact Bosch Customer Support at 1-800-944-2904.

Clearing an error code on a Bosch dishwasher can typically be done by resetting the dishwasher. The process can vary slightly depending on the specific model of your Bosch dishwasher, but the general steps to attempt a reset are as follows:

1. Turn Off the Power: Begin by turning off the dishwasher. You can do this either by pressing the power button on the dishwasher or by shutting off the power at the circuit breaker for a minute. Turning off the power will force the dishwasher to reset.

2. Wait: After you have turned off the dishwasher, wait approximately 1 minute. This pause allows the dishwasher's electrical components to discharge and can help in clearing error codes.

4. Run a Test Cycle: After the dishwasher has been reset, run a short test cycle without any dishes in the dishwasher to ensure that the error code has been cleared and the appliance is functioning correctly.

A Bosch dishwasher error code E01, E02, E03, E04, or E05, refers to a power module failure, i.e., a control board issue requiring specialist attention. Bosch recommends calling its customer service at 1-800-9442904 or a Bosch certified technician to fix the problem.

An E01 error code usually refers to a pump control circuit failure on the main control board. With some models, the issue can cause a lack of water in the dishwasher, which stops the heater from running and triggers the error code.

An E03 error code most likely refers to an auxiliary heater relay fault on the main control board. However, with some models, it may indicate that the water inlet valve needs to be replaced because the dishwasher cannot fill with water.

The E04 error code usually refers to a heating issue, which is difficult to diagnose and requires a trained Bosch technician. With some models, it may indicate that a spray arm is clogged and needs cleaning, or that the water flow sensor needs to be replaced.

The most likely cause of the E05 error code is a water switch Triac fault on the main control board. In some cases, the error code indicates a damaged float or defective float switch. Before contacting a Bosch technician, you could replace the float and/or float switch to see if it resolves the error code.

Depending on your model, the dishwasher door may not be closing properly, or the aqua sensor may have a fault. A door mechanism failure is most likely, but unfortunately, the sensor is difficult to access, and a door mechanism failure can be difficult to diagnose.

The aqua sensor (also called the turbidity sensor) monitors the water quality, such as whether the water is clean or dirty. Checking the aqua sensor requires dismantling the dishwasher to locate the sensor on the circulation pump.

If the door is closing and locking, the sensor switch that monitors the door may be faulty and need to be replaced, or the main control board may have a fault that requires a Bosch technician to diagnose and fix.

The resistance of the thermistor (integrated into the heat pump on newer models) or the NTC (temperature sensor) needs to be checked to diagnose the issue (see the tech sheet for the required resistance).

First, determine if you can see where the leak is coming from. If the dishwasher does not appear to be leaking, the flood sensor in the drain pan underneath the tub may be defective. Otherwise, a hose may be loose, or a gasket or spray arm may be damaged.

If you can hear the drain pump working without issue, check that the drain hose is not clogged. The drain pump can be inspected for a mechanical failure or tested for an electrical failure with a multimeter continuity test.

The E15 error code on a Bosch dishwasher means that the dishwasher has detected too much water and there's a risk of a leak. The control board receives a signal from the flood switch, activates the water pump to drain the water, and then turns the dishwasher off. The error code could also be caused by a control board glitch.

Hello i am currently working with the BNO055 driver api (version 2.0.6) that is provided by BOSCH.My sensor software revision is 3.11. I am having a bit of trouble calibrating the BNO055 sensor. No matter how long i try to calibrate the sensor the SYS_Calib status remains 0 however i am able to get the accel,mag and gyro fully calibrated. i heard that the sensor can still be used if accel,mag, and gyro all reach 3 and that its ok to ignore the sys status but i would like to confirm this. I would like to reuse the calibration profile but the offset values that i am seeing are all 0 except for the mag radius which is 480. I suspect that these offset values are mostly zero because the sys status that was not fully calibrated but i am not sure. I have also noticed that the system error code register is set to 5 which means that "Register map address out of range" as stated in the manual. The system error code register is always at a value of 5 after the bno055_init function and i am not sure why. I suspect that this might be the reason why the sys status wont change at all. I have another BNO055 sensor that is new and has the same software revision 3.11 and it works completely fine running the same code and the system error code register on the new one is 0. I would like to get my other sensor to work though because it used to work before and this problem only started recently. I am using the read template function from BOSCH's api with some added code to read the system error code register and calibration so its nothing special, i dont think the code is the issue as i have said before it works on the new sensor. Is there any thing i can do to fix the system error code value of 5? Thank you

Which mode you configured?

When I configured BNO055 mode to NDOF mode with BNO055 shuttle board, calibration status of accel, gyro, mag, system could reach up to 3. What about your test environment?

I am not using the shuttle board, but instead using the bno055 sensor sold from adafruit. I am also in NDOF mode and my test environment is just my room, so nothing special. I read in another forum post that the sys status may have a bug that causes it to get stuck at 0. the link to the forum post is below:

Apparently if you update the firmware it may resolve the issue that causes sys status to stay at 0. However there does not seem to be an easy way to update the firmware unless perhaps you know of a way to do so without use of the application board?

If you install development desktop software, you could refer document "C:\Program Files\Bosch Sensortec\Development Desktop 2.0\DD2.0_BNOxxx.pdf" to upgrade BNO055 firmware.
