Failure Code # |
Description of Fault Code |
Solution for Fault Code |
1-1 |
The electronic control board detects a stuck relay on its circuit board. |
Dishwasher power should be turned off for five minutes. If the code reappears after power is restored, get a service professional to examine the wiring and components. Replace the electronic control board if the wiring and parts are functional. |
1-2 |
Damaged or corrupted memory on control board. Incompatible software components inside microprocessor. |
Dishwasher power should be turned off for five minutes. Replace the electronic control board if the code reappears after the power is restored. |
2-1 |
The electronic control board detected a stuck key on the control panel. |
Check if any of the keys work. Replace the electronic control panel if any of the keys are broken or the control panel is damaged. If the control panel functions properly, the electronic control board may be the source of the issue. |
2-2 |
The electronic control board detects no communication from the control panel. |
Check if any of the keys work. Replace the electronic control panel if any of the keys are broken or the control panel is damaged. If the control panel functions properly, the electronic control board may be the source of the issue. |
3-1 |
Either there’s a break in the wiring or the thermistor/OWI component failed. (The thermistor is the water temperature sensor, the OWI is the Optical Water Indicator that detects the amount of debris in the water.) |
Check the wiring for the thermistor/OWI circuit after turning off the dishwasher’s power. Replace the thermistor/OWI component if the circuit wire is intact. |
3-2 |
The thermistor/OWI circuit is electrically shorted, (The thermistor is the water temperature sensor, the OWI is the Optical Water Indicator that detects the amount of debris in the water.) |
Check the wiring for the thermistor/OWI circuit after turning off the dishwasher’s power. Replace the thermistor/OWI component if the circuit wire is okay. |
3-3 |
OWI fails (the OWI is the Optical Water Indicator that detects the amount of debris in the water) |
Dishwasher power should be turned off before cleaning the OWI. Replace the OWI if the code reappears after power is restored. |
4-1 |
No communication between the electornic control board and the wash pump motor |
Dishwasher power should be turned off before inspecting the wiring from the control board to the wash pump motor. The wash pump should be changed if the wiring is unharmed. You should swap out the electronic control board if the issue continues. |
4-2 |
Communication error between the electronic control board and the wash pump motor |
Dishwasher power should be turned off before inspecting the wiring from the control board to the wash pump motor. The wash pump should be changed if the wiring is unharmed. You should swap out the electronic control board if the issue continues. |
5-1 |
Door won’t latch shut |
Close the door as soon as you press the Start button. If the error persists, turn off the dishwasher’s power and inspect the door latch system and the wiring that connects to the door switch. Replace the door switch if the wiring and latch mechanism are sound. |
5-2 |
Door won’t open |
Verify the door switch’s wiring. The door switch should be replaced if the wiring is okay. |
6-1 |
The electronic control board doesn’t detect water entering the dishwasher tub. |
Put water in the dishwasher, then turn off the power. Make that the water supply is flowing and pressing properly. Verify the water inlet valve’s wiring. Replace the water inlet valve if the wiring and water supply are functional. |
6-2 |
Water inlet valve has an electrical problem. |
Put water in the dishwasher, then turn off the power. Make that the water supply is flowing and pressing properly. Verify the water inlet valve’s wiring. Replace the water inlet valve if the wiring and water supply are functional. You should swap out the electronic control board if the issue persists. |
6-3 |
Suds or air are in the water pump |
Inspect the tub’s fill water for suds and the level of water in the tub. Change the water inlet valve if the fill level is too low. Check the detergent dispenser and replace it if necessary if there is an excessive amount of sudsing. |
6-4 |
The float switch is open |
To see if something is under the overfill float switch or if it is stuck, check it. Verify that the inlet water fill valve effectively turns off the water supply while the dishwasher is not in use. |
6-6 |
Incoming water is too cold |
Check the temperature of the water with an accurate thermometer. Check your water heater if the temperature is lower than 110 degrees F. Replace the thermistor/OWI or the electronic control board if the water temperature is normal (between 110 and 120 degrees F). For a thermistor diagnostic test, consult the tech sheet for your dishwasher. |
6-7 |
Disconnected or damaged flow meter |
Dishwasher power should be turned off. Verify the flow meter’s wiring. Replacing the flow meter is advised if the wiring is functional. |
6-8 |
Problem with water softener regeneration valve |
Dishwasher power should be turned off. Verify the water softener regeneration valve’s wiring. Replace the water softener regeneration valve if the wiring is ok. |
7-1 |
Heating element doesn’t work |
Dishwasher power should be turned off. If the heating element is clearly damaged, examine it and replace it. If not, look at the heating element’s wiring. Replace the heater element if the wiring is sound. |
7-2 |
Heating element won’t shut off |
Dishwasher power should be turned off for five minutes. Replace the electronic control board if the code reappears after the power is restored. |
8-1 |
Slow drain |
Turn off the water first, then the power of the dishwasher. Check for blockages along the drain path. Check the wiring on the drain pump if the drain path is clear. The drain pump should be changed if the wiring is sound. |
8-2 |
Drain pump electrical problem |
Turn off the water first, then the power to the dishwasher. Verify the drain pump’s wiring. The drain pump should be changed if the wiring is okay. |
9-1 |
Electronic control board can’t detect the position of the diverter |
The diverter controls whether the water is sent through the upper or lower spray arm. Dishwasher power should be turned off before checking the wiring for the diverter motor. Replace the diverter if the wiring is okay. |
9-2 |
Diverter is stuck on |
Remove both the lower spray arm and the lower dishrack. Take the sump apart. When the diverter disc is damaged, replace it. |
10-1 |
Dispenser electrical problem |
Dishwasher power should be turned off. Check the wiring in the circuit for the detergent dispenser by removing the outer door panel. Change the detergent dispenser if the wiring is okay. |
10-2 |
Vent wax motor electrical problem |
Dishwasher power should be turned off. Verify the vent wax motor circuit’s wiring. The vent wax motor should be changed if the wiring is sound. |
10-3 |
Drying fan problem |
Dishwasher power should be turned off. Verify the wiring in the circuit for the drying fan. Change the drying fan if the wiring is okay. |
