Question about Bosch 24 in. SHU43 Built-in Dishwasher
Hello Gary, 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 shu43 series 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. Whentestimg 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 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. Part # 1105846 at "repairclinic.com" 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. Good luck. Macmarkus :)
