Bosch My bosch dishwasher shows an "F" on the display when started. It sounds louder than usual but the cycle doesn't start. I made sure there were no obstructions, debris, etc but no help. Thanks.

Hi!

here are manuals to BOSCH dishwashers. Please kindly check if there is a manual to your device which helps you to solve the problem. https://manualsbrain.com/en/brands/bosch/dishwashers

Open the dishwasher door sufficiently to see the control buttons, then hold the two buttons with labels "Cancel Drain" and press for 3 seconds.
Close the door. Wait nearly 1 minute for the dishwasher to complete the cycle.
Open the door and hold the "ON/OFF" toggle.

Reset Bosch Ascenta Dishwashers
Shut off the child lock if needed by pressing and holding "Open the door far enough to see the keys, then hold the "START RESET" toggle until the "ACTIVE" LED become extinguished. On the SHE5AM model of Bosch Dishwashers, hold the "START RESET" key until the display clock shows "0:01".
Close the door and rest about 60 seconds. On the SHE5AM, wait until the display clock displays "0:00".
Open the door and hold the "ON/OFF" toggle.

Some Bosch dishwashers have a time delay option. The H01 indicates a one hour delay has been selected. Press the Delay key several times until you see H00 in the display. Then try to start the dishwasher cycle you need. Bosch error codes tend to start with E.

Please add a comment with the model number of the dishwasher if you need additional help. (Without the model number, I can't be sure which key sets the time delay. On some models, the key is near the On/Off button. On others, it's closest to the Start button.) I hope this helps.

Here is an excerpt from "Bosch Dishwasher Troublesoooting".

Running a Test Cycle
Bosch dishwashers have a test cycle which can be run as a troubleshooting measure. The method to run this test cycle is similar across the Bosch dishwasher range so if your dishwasher features seems different from those described below then try experimenting, as the process is fairly straight forward and will be very similar. Bosch dishwasher model numbers are usually found around the top or lip of the door. One of the most common differences between dishwasher models is simply the names of the buttons. For example in the first example below, POWER SCRUB PLUS and REGULAR WASH may be called WASH and ECO depending on your dishwasher model and the country you are in. The other key difference is whether your dishwasher has a display panel (which can display error codes) or not (in which case a program light will illuminate to tell you the fault.
To run the test cycle hold down the POWER SCRUB PLUS and REGULAR WASH buttons. Whilst held down press the ON/OFF button. The lights above them should flash. Now you can check the status of each dishwasher program by pressing its button. Now you can run the full test cycle = Press the POWER SCRUB PLUS and REGULAR WASH buttons again. The dishwasher will start up and when the cycle has ended one, if you have no display panel on your dishwasher model the indicator lights will illuminate if a malfunction was detected as follows -
CLEAN - A temperature sensor fault. If this is the case then the test cycle will be very short as the dishwasher will terminate the test once it's been detected.
RINSE/DRY - A water sensor/filling fault. If this is the problem then the test cycle will not complete as the dishwasher cannot detect the right level of water, the dishwasher will just keep filling and draining again.
WASH - A heating fault. Check your heating element.
If you do have a display panel on your Bosch dishwasher then after the cycle is complete an error code will be shown if a fault has been detected. The error codes are as follows -
0 - No errors have been detected.
1 - A water sensor/filling fault.
2 - A heating fault.
4 - A water filling fault. This can also appear as F on the display during a normal cycle.
8 - A temperature sensor fault.
When troubleshooting your Bosch dishwasher, running the above test cycle is a good start in diagnosing the problem and should give you an idea of where the problem lies with your Bosch dishwasher and what fixes and repair are in order. Our general troubleshooting page will give you some ideas on other things to check on your dishwasher. Good luck!

When you start a wash cycle on your Bosch dishwasher and it does not work, stay calm. It could be something simple, especially if you just installed it. Make sure the power cord is connected properly and a circuit breaker did not trip. How to Troubleshoot Bosch Dishwasher That Doesn Fill With Water

My Bosch dishwasher did the same thing. When the wash cycle starts, the dishwasher fills with water and then the heater is supposed to turn on to heat the water. If the water does not heat, then it will display 2H continuously. The heating element may be bad, but a more likely cause is with the control module. Bosch has a problem with the control module printed circuit (pc) board that powers the heater on many models. The solution requires some technical expertise and soldering skills. The details are explained in the document "Bosch dishwasher troubleshooting tips" on page 11. Download here
Bosch recommends re-soldering the connection, which is a temporary fix. The problem is that the copper conductor (called a trace) on the circuit board is not wide enough to handle the current required for the heating element, and as a result the copper trace overheats, causing the solder to melt on the relay connection. The best solution is to remove the control module PC board and solder a short length of copper wire between the pins to prevent the overheating problem, as shown in the attached photo (magnified portion of PC board). I did this on my dishwasher and it has been trouble-free for over 3 years.

UNfortunately that sounds like the controle module and you can not have that fixed. only replacement of the part will fix that problem

Hello zeviemail
Welcome

You said, your Bosch dishwasher on auto wash will stop functioning in middle of the cycle start beeping and there is an icon of a faucet on the display.


What is your model number and the year of the dishwasher?

OK, I think I have figured this out. Let me first give this important piece of information. The control panel for my dishwasher was replaced recently. That's why I now have to deal with this issue. I have a Bosch SHY66C model. As I stated in a previous post, the user manual I found on the web has identical structions for changing the amount of rinse aid dispensed and for changing the volume on the cycle completion beeper (or for disabling it). Following the instructions fixed the former.

Here is what I did

1) With dishwasher off, I pressed and held the "Delay Start Hours" button
2) I pressed the on/off button. The beeper begin to sound.
3) I released both buttons (not sure this step is necessary)
4) I repeatedly pressed the "Delay Start Hours" button until the signal turned off
(LED display showed 0)
5) I pressed the on/off button (not sure this still is necessary)

That seems to have fixed the problem. So, I don't know if the user manual is wrong or my control panel was replaced with one from a different model (such as the SHU9950 where I found these instructions).

sadly enough, same problem. looks as though micro processor is defective.
