Hello Randall,
Try running a diagnostic mode. Press the High-Temp and Start-Cancel buttons on the dishwasher and hold them until the test begins. Release them if you see other indicators light up on the top edge door controls. For dishwashers equipped with a digital display, "01" should appear in the display window to indicate the test has begun. Allow the dishwasher to work its way through its self-test of the various components such as the water fill, drain pump, wash motor, heating element and more. While it goes through these tests, you will hear the individual components activate. If there are no other problems with the dishwasher, it should reset itself at the end of its self-diagnosis. If it fails to reset and an error code appears in the small window you need to check the electrical parts with a test meter indicated by the error code.
Frigidaire Dishwasher Error Code = i10 = A low fill has been detected. Check for a pinched water supply line, or water shutoff is not completely opened.
Frigidaire Dishwasher Error Code = i20, i40, iF0 Check for clogged filters or a restricted drain line has been detected. Check and clean both filters and sump area and check for a pinched or blocked drain hose. If the drain line is attached to a disposer, check that the knockout plug has been removed.
Frigidaire Dishwasher Error Code = i30 A leak or over flow of water has been detected in the bottom pan. Look for loose connections at the water inlet valve and ensure the unit is properly leveled.
Frigidaire Dishwasher Error Code = i50 A problem has been detected with the drain or wash motor. Pressing the cancel button or turning power off at the breaker for 5 minutes should clear this error code and the unit can be restarted.
Frigidaire Dishwasher Error Code = i60 A problem has been detected with the water heating system. Pressing the cancel button or turning power off at the breaker for 5 minutes should clear this error code and the unit can be restarted.
Frigidaire Dishwasher Error Code = iC0 A problem has been detected with the electronic control system. Pressing the cancel button or turning power off at the breaker for 5 minutes should clear this error code and the unit can be restarted.
Frigidaire Dishwasher Error Code = UO Vent open While in wash cycle, Main Control Board does not receive signal from vent assembly that vent plunger is closed. Plunger status is sensed with optical sensor in vent assembly. Check wiring between vent assembly and Main Control Board. If wiring correct, replace vent assembly. If error still exist, replace Main Control Board.
Frigidaire Dishwasher Error Code = UF Fan not running While in drying cycle, Main Control Board not sensing vent fan motor rotation at correct speed. Check wiring between vent assembly and Main Control Board. If correct, replace vent assembly. If error still exist replace Main Control Board.
Frigidaire Dishwasher Error Code = ER Membrane Switch Failure Main Control Board has detected a stuck key or a key pressed for more than one minute. Check connection from keypad to Main Control Board. If correct, replace keypad. If error still exist, replace Main Control Board.
Frigidaire Dishwasher Error Code = CE Configuration Error Check wiring connections between keypad and Main Control Board. Check for correct parts installed. Replace parts accordingly.
Frigidaire Dishwasher Error Code = CL Close Door – Door Switch Open Main Control Board not sensing door closed. Close door. Check door switches. Check wiring between door switches and Main Control Board. If wiring and switches are correct, replace Main Control Board.
Frigidaire Dishwasher Error Code = dP Drain Pump Displayed in relay test when drain pump is activated.
Frigidaire Dishwasher Error Code = FL Water Valve Is Open Displayed in relay test when water valve is activated.
Frigidaire Dishwasher Error Code = HO Heat Delay The control is delaying cycle to allow water temperature to rise to correct temperature in attempt to assure optimum performance.
Frigidaire Dishwasher Error Code = hs Hall Sensor The control has sensed an error with hall sensor in motor. Check wiring between motor and Main Control Board. If correct, replace motor. If error still exist, replace Main Control Board.
Frigidaire Dishwasher Error Code = LO Low Rinse Aid Rinse aid level is low. Refill rinse aid dispenser.
Frigidaire Dishwasher Error Code = PF Power Failure A power failure has occurred. More than 10% of power has dropped to the unit. Check house wiring.
Frigidaire Dishwasher Error Code = rA Rinse Aid The control has sensed a problem with the reed switch in the dispenser. Refill the rinse aid dispenser. If error still exist, check wiring between dispenser and Main Control Board. If not corrected, replace dispenser assembly. If error still exist, replace Main Control Board.
Frigidaire Dishwasher Error Code = RE Rinse aid reed switch Rinse aid reed switch in dispenser is closed.
Frigidaire Dishwasher Error Code = RF Rinse aid Rinse aid reed switch in dispenser is open. Refill rinse aid dispenser. Replace dispenser assembly.
Frigidaire Dishwasher Error Code = rt Relay / Triac Test Relay test mode has been activated.
Frigidaire Dishwasher Error Code = Sd Detergent Dispenser Displayed in relay test mode when detergent dispenser is activated.
Frigidaire Dishwasher Error Code = tu Turbidity Sensor The Main Control Board has sensed a failure in the turbidity sensor. Check wiring. If wiring correct, replace turbidity sensor. If error still exist replace Main Control Board.
These are all of the fault codes I could locate on your unit. Please try the reset and let us know if further assistance is needed.
