F4 is typically related to a drainage problem.
If the water is not draining from your dishwasher, verify the following:
Verify that there is not a clog in the drain hose or air gap. This is typically the reason that a dishwasher won't drain and the clog is usually where the drain hose attaches to the garbage disposal or sink drain pipe. Remove the hose and clear any clogs, then reinstall.
Verify that the pumps drain impeller is working. You can reach the impeller from inside the dishwasher after removing the lower rack, spray arm, and arm support. This typically involves removing a few screws. Once upper parts are removed, inspect the drain impeller, which pushes the water toward the drain port, for any cracks or missing blades. If the impeller is defective, the water will not drain properly and you would need to replace it. Inspect the sump area for any debris or broken glass that could be blocking any ports.
Verify that the drain valve is working; many are controlled with an electric solenoid that opens the valve, sending the water to the drain. There is a chance that the solenoid or the diverting lever could be stuck which would prevent the water to drain. If so, try to free up the solenoid and lubricate the lever. Otherwise the solenoid or pump assembly may have to be replaced.
Verify that the motor is turning/ working and verify that there is power to the motor. If the motor hums but doesn't turn, it may need to be replaced. Motors can get stuck if not used regularly. If the motor is defective, the water will not drain and you would need to replace it.
There are ways to test the pump and motor with a multimeter. If you are not comfortable with doing this, you may want to have a plumber test it for you.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!

Unplugthe power cord to your dishwasher. You can do this by manually removing thedishwasher from the wall and unplugging it, or you can flip the power switch toyour kitchen at the circuit breaker (although you will need light to drain thedishwasher hose). 2 Put on your gloves,and, using your screwdriver, unscrew the screws from the kick plate of yourdishwasher. The kick plate is the panel just below the door of your dishwasher.3 Place your bucket on the floor in front of the dishwasher. 4 Unhook the drainhose by pinching the ends of the clamp and sliding it down the hose. Remove theother end from the pump. There will be two hoses in your dishwasher. The drain hoseis the one that leads from the pump to the underneath of your kitchen sink. 5 Pointthe hose into your bucket to drain any debris. Twist and scrunch the hose tohelp remove the waste. 6 Test the hose by running water through it, and thenreattach your hose in the same manner in which you detached it from yourdishwasher.
