Hi, welcome to Fixya.

Based on the info you've provided, the dishwasher is indicating a error during the "fill" stage, hence the "F" being displayed on the Bosch machines.

Here's how to perform a test or diagnostic...

Make sure the power button is in the off position ( open & closing of the door will activate the "auto shut off" ).

Once certain it is "off" press and hold both the regular button and rinse & hold button, then turn the unit "on" while continuing to depress those 2 buttons. Initially, control module version # will display ( i.e. "20" = version "0" without jumper...not important for this ).

When the buttons are now released, the lights above them will flash. To start testing, press both the "regular wash" and "rinse & hold" a second time.

Let the test follow through, ( grab a coffee and observe, this will take a while )

When testing has ended, the display will show an error using codes as follows...
"0" = no error.
"1" = aqua sensor fault.
"2" = heating fault.
"4" = filling fault. and finally.
"8" = NTC ( temperature sensor ) fault.

The "F" code will not appear in test mode, only during wash. If you have a failed level switch for instance the test will display "4" and will continually fill and drain and test won't complete until you press the "on/off" button.

If the test complete's without and error or won't fill, replace the water valve. Original part Part # 425458 at "searspartsdirect.com", "apwagner.com" or #1105846 at "repairclinic.com" ( they use there own numbers ) or you can check locally by your model number & serial number.

Let me know if I can assist you further. Hope you found this helpful and if so please allow for a positive rating.

Thank you for choosing "fixya" and good luck.

I have a SHU5305us/u12 and my front door lettering got erase. anyone have a picture or a manual that tells me what each button means.


Cycle Interruption

As a safety feature the dishwasher will automatically turn itself off whenever the door is opened. However, if the door is opened quickly while in a wash or rinse cycle some water may splash out of the dishwasher. For this reason it is recommended that the machine always be switched off before opening the door.



To Interrupt a Cycle

1. Press the on/off button to stop operation.

2. Wait at least 10 seconds (or until the water noises stop) before opening the door.



To Resume a Cycle

1. SHU/SHI models, close the door and press the on/off button.

2. SHV models, push the on/off button and close the door.



Changing a Cycle

For Bosch dishwasher models SHI 6800 and 4320, SHU 5300, 5310 and 6800 press the program button of the desired cycle TWICE. For all other Bosch dishwasher models, press the program button of the desired cycle ONCE. The chosen cycle button (or the light above it) becomes illuminated, showing that it has been selected.

* SHU 3030 and SHU 3130 models do not have program lights.



Cancelling a Cycle

Each control panel shows which buttons to simultaneously push to cancel a cycle. Refer to your dishwasher to find the cancel drain buttons on your particular model.



1. Press the indicated buttons at the same time and hold for approximately 3 seconds.

2. When the drain pump noises stop and the LED display or clean light indicate that the end of the cycle has been reached, the dish

washer is reset.

3. Press the on/off button to turn the dishwasher off.

4. The dishwasher is now ready to run a selected cycle. Add more detergent if necessary.

Dishwasher LED not lighting and dishes not cleaned


If it's making a sound, that means you have power. You may need a control board or a console or both. Check the ribbon cable between the console and the control board for any loose connections. If everything is fine, replace the parts.

If you check your user manual there is a section that will guide you through turning off/on the display screen. I have tried to include the link for Bosch manual downloader but their site is down at the moment. If you do not have your manual and therefore cannot rectify the fault, please repost or comment on this solution and hopefully the site will be back on and I can reply with the link.
All the best

One year old Bosch dishwasher stop wrking.will not


Start with the basics: Check the status of the breaker and the electrical connections under the toe kick panel. If the unitis getting power, You may want to call the dishwasher helpline to see if it is a recalled model. A free replacement of the control panel circuit board is available for many of these, but if the power switch is the culprit, you will need to buy a replacement button.
I have written a guide to help with drainage issues. The helpline number is near the top. It is here. Thanks!

I cannot be sure of the make/model - there is no power


It sounds like you have a bad controller which is an expensive part if it is over five years old. However, there is a recall on some Bosch dishwashers which involves replacing the control. If you call Bosch at 1-800-944-2904 they can tell you if your model is involved in the recall.
