Bosch aquasensor dishwasher, -F- in display not working

Hello, I have a Bosch Aquasensor dishwasher. When I switch it on the display, which usually shows the time remaining for the program to run, shows -F- in the display. I don't know what this means as it does not mention this in the manual at all! I have checked whether the filter is blocked or dirty and I have checked the filter at the water inlet. I have disconnected the machine several times but to no avail.
I must also mention that it sounds as if the pump is running as there is a noise coming from the top left side of the door. It's more the sound the machine makes when it is running fine but this time it just makes the sounds without taking in any water or cleaning anything!
Help! Do you have any helpful suggestions?
I look forward to your reply.

SOURCE: Bosch Aquasensor Detergent Dispenser door wont open during cycle

Behind the dispensor door there is a small selanoid you will need to replace this, test to see if its open circuit, alternatively you can just place the detergent in side the machine before you put it on a wash cycle is this would have the same effect. the only cycle you can not do this on is the one with the prewash, I think its number 1.

The dishwasher has been running for 3 hours and seems to be stuck on 1 minute left. Upon opening, there was sudsy water remaining in the bottom, but the dishes looked clean. The washer just won't go to...


SHU 53 MODELS To start test program, press and hold both SCRUB WASH and DELICATE/ECONO program buttons, then turn unit on by pressing ON/OFF button. Initially, control module version # will be displayed (e.g./ ?21? = version 1 with jumper). When wash program buttons are released, lights above them will flash. To end test program, press ON/OFF button. To check each program indicator light, press its button. To check Cycle Countdown display, Refill Rinse Agent light and REGULAR WASH light, press REGULAR WASH button (press Delay Start button to test Cycle Countdown display alone). Cycle Countdown display will show ?88″ when REGULAR WASH button is pressed and ?8h? when Delay Start button is pressed. To start testing, press both the SCRUB WASH and DELICATE/ECONO buttons a second time. When testing has ended, Cycle Countdown display will show a fault using codes below. If more than one fault occurs, code numbers will be added together, (e.g./ ?6? = faults 2 + 4). 0 = No faults detected 2 = Heating fault 8 = NTC (temperature sensor) fault 1 = Aqua Sensor (?Sensotronic?) fault 4 = Filling fault F = Filling fault (display occurs during wash, not test) To check for heater, high limit or flow switch problems, start testing until heating starts. Using a meter with a current coil, measure current going into dishwasher. If current is ~ 11 A, then heater, high limit and flow switch are OK. If current stays at ~ 1.5-2 A, then heater, high limit or flow switch are faulty. If water level switch (f1) has failed (opened), display will show fault code ?4″ and unit will continually fill and drain where testing won?t be completed. If flow switch (e5) has failed (opened), display will show ?0″, water won?t heat (to 150?F) and water won?t stop circulating. If NTC probe (f2/f4) has failed (opened), display will show fault code ?8″ immediately and testing will end shortly after water has started circulating.

BAD CONTROL BOARD TO TEST TO SEE IF THIS IS THE ISSUE RUN TEST PROGRAM
To start test program, press and hold both SCRUB WASH and DELICATE/ECONO program buttons, then turn unit on by
pressing ON/OFF button. Initially, control module version # will be displayed (e.g./ “20” = version 0 without jumper). When
wash program buttons are released, lights above them will flash. To end test program, press ON/OFF button.
To check each program indicator light, press its button. To check Cycle Countdown display, Refill Rinse Agent light and
REGULAR WASH light, press REGULAR WASH button (press Delay Start button to test Cycle Countdown display
alone). Cycle Countdown display will show "88" when REGULAR WASH button is pressed and "8h" when Delay Start
button is pressed.
To start testing, press both SCRUB WASH and DELICATE/ECONO buttons a second time. When testing has ended,
Cycle Countdown display will show a fault using codes below. If more than one fault occurs, code numbers will be added
together, (e.g./ “6” = faults 2 + 4).
0 = No faults detected 2 = Heating fault 8 = NTC (temperature sensor) fault
1 = Aqua Sensor ("Sensotronic") fault 4 = Filling fault F = Filling fault (display occurs during wash, not test)
To check for heater, high limit or flow switch problems, start testing until heating starts. Using a meter with a current coil,
measure current going into dishwasher. If current is ~ 11 A, then heater, high limit and flow switch are OK. If current stays
at ~ 1.5-2 A, then heater, high limit or flow switch are faulty.
If water level switch (f1) has failed (opened), display will show fault code "4" and unit will continually fill and drain where
testing won't be completed. If flow switch (e5) has failed (opened), display will show "0", water won't heat (to 150ºF) and
water won’t stop circulating. If NTC probe (f2/f4) has failed (opened), display will show fault code "8" immediately and
testing will end shortly after water has started circulating

Bosch aquasensor diswahing machine


To reset the board so as the times will go back to factory settings.
Turn appliance on press both buttons that have the two dots under, the display will then go back to zero. Shut the door and allow appliance to reset itself. This normally takes about a minute, whilst it's doing this the pump will be running.
Hope this helps
