the electronic computer board is dead & needs to be replaced.

F3 comes up on mine as well and has the problem. It has been said that F3 means a water leak!!

Hi

If the water inlet valve is fine and it fills with water then the issue seems to be with the float switch assembly that is bad and should be replaced. Float assembly is found inside the dishwasher's tub, on the bottom. The water that fills the dishwasher lifts the float, and when it reaches a certain level, it acts as a trigger for the float switch. The float triggers the float switch to shut off, thereby shutting off the flow of water into the dishwasher. A defective switch may interfere with dishwasher's filling and/or draining ability. Use voltmeter to test the switch. Set the device to the ohms setting x 1. Take each probe and touch them to one switch terminal each. This should produce a reading of either zero or infinity. Continue to touch the probes to the terminals, and press down on the switch's button. The reading should change to the opposite extreme. If the switch fails either of these tests, you should replace it. Hope this helps...please post back for further assistance.

THIS CODE INDICATES THAT THE WATER LEVEL SENSOR LOCATED ON THE SIDE OF THE D/W IS FULL OF GUNK AND DEBRES (I/E MOLD AND DEPOSITS) YOU HAVE TO UNINSTALL THE DISHWASHER, AND TAKE THE LEFT SIDE OF THE PANEL OFF ON THIS UNIT AND CLEAN THAT BOX OUT BY UNSCREWING THE WATER INLET HOUSING INSIDE THE DISHWASHER. (THAT GRAY SCREEN) UNSCREW THIS INLET ON THE LEFT INSIDE THE DISHWASHER. NOTE: THERE IS A SEAL ON THE OTHER SIDE OF THIS. DISCONNECT THE WIRE HARNESS AND THE CLAMP ON THE REAR RIGHT SIDE OF THE FLOAT BOX. BE SURE NOT TO GET ANY WATER INSIDE OF THE DISHWASHER OR YOU WILL HAVE TO DRY IT UP OR WAIT FOR IT TO EVAPORATE. I WOULD SUGGEST USING PAPER TOWEL WHEN REMOVING THIS PART. NOW YOU HAVE THE OPTION OF EITHER CLEANING IT OUT BY DISASSEMBLING THE BOX AND GETTING THE BACTERIA OUT, OR SIMPLY ORDERING A NEW ONE AND JUST INSTALLING IT. ONCE THE BOX IS CLEANED OUT, THE FLOAT MECHANISM IN THE UNIT CAN FLOAT FREELY TELLING THE WATER WHEN TO SHUT OFF. ONLY PERFORM THIS REPAIR ON A DISHWASHER THAT HAS THE POWER OFF TO IT.

i got 3 times this code in less than 2 years and motherboard has to replace.technician said samsung dishwashers got bad system.

Thank you, worked like a charm. So simple. It needs to be done annually, as a regular maintenance...

Check your belts they might be worn

Maybe try a liquid detergent, and leave the little door open. GOOD LUCK

It is possible that the machine does not start off the cycle because there are errors or feedback from the inputs. For the program to start up the main program controller must initiate the INLET/PUMP MOTOR/DRAIN to work when it is commanded .If this does not happen then the voltage at these points must be checked or the fault relates to no voltage/drive from the controller. This means the controller is a suspect.

Check how to remove the control panel: http://www.espares.co.uk/advice/dishwashers/a/3/1287/how-to-replace-a-hotpoint-dishwasher-fascia-p.html

If the water flows then the flow should be good, if not the inlet valve is bad or there is dirt in the filter. Also check the flow at the inlet of the water line. What is most important for the motor to start functioning is that the door switch must be ON when the door is shut or this will be an error for starting the motor. The water pressure must be good and the spraying must be seen to be good. If there is low pumping or pressure then the spray arms will not turn around to inject with pressure. If so the pump must be checked for clogging.
