Modern dishwashers have digital screens. If something is wrong, an error message appears on the screen at a glance. This makes troubleshooting easier. You may find an error code popping up on the display and you need to find out what the code means to solve the problem. We do not recommend doing the dishwashers repair yourself. It is best to entrust it to professionals. Then you can be sure that your dishwashers will be in good working order. Sometimes you will need to run a diagnostic test to see the error code. The Most Common Dishwashers Error Codes and Resolutions.
There are several common dishwasher error codes. The most common error codes mean: dishwasher not draining properly, water not heating or water not pouring/draining, leakage, blocked rotor, intake valve problems, filter failure and other dishwasher errors. These codes can be caused by a variety of factors, from a faulty heating element to a clogged drain hose.
What do the codes on dishwashers mean?
All of the errors and codes on dishwashers mean a large number of malfunctions and other information about the condition of the unit. We’ll highlight the main ones and break down the most popular errors from popular dishwasher brands in the United States. Some of them can be fixed by yourself, while others require contacting professional appliance repair technicians.
When an error appears on your dishwashers, it is advisable to contact a dishwasher repair technician right away. At least over the phone: call and tell them what kind of characters show on the display – perhaps it is necessary to urgently turn off the device. Without experience and special equipment, restoring the operation of a complex problem of the dishwasher is not possible. Let’s look at the most popular dishwashers errors of some brands.

The Most Common Whirlpool Dishwashers Error Codes and Resolutions
|Whirlpool dishwasher error code F1
|The code is triggered by the temperature sensor. Depending on the extremes in water temperature — it can be too cold (below -3°C) or too hot (above 85°C) — the thermistor in the dishwasher returns this code. However, keep in mind that the temperature sensor may fail and work incorrectly and also trigger an error like this. Consequently, consider replacing the sensor if it is faulty.
|Whirlpool dishwasher error code F5
|The drive has experienced a rotor blockage. This error lights up when a problem with the drive rotor (the rotating part) occurs. Chances are extremely high you will need to have the dishwasher drive replaced.
|Whirlpool dishwasher error code F7

|Whirlpool dishwasher error code FA
|The malfunction of the optical water sensor. Your dishwasher will return this code if there is a problem with the optical water sensor in it. The sensor may not actually be faulty but indicate that the water inside the dishwasher is very dirty. This condition triggers an additional rinse cycle. If the error persists, your optical sensor may be blocked with dirt and need cleaning. If it does not help, you may want to examine the sensors for their firm connections to the dishwasher control panel. This error code may also light up if you add too much detergent during your wash cycle and it causes excess foaming that prevents the sensor from making accurate readings.
|Whirlpool dishwasher error code FB
|The dishwasher has an issue with the diverter valve. The code will be on if the dishwasher experiences problems with diverter valve operation. This valve directs the water flow to the upper spray arm. Check this valve for any malfunctions and replace it if necessary.

The Most Common Maytag Dishwashers Error Codes and Resolutions
|Maytag dishwasher error code 1-2
|The condition when all the LEDs light up. It happens due to the user interface control panel’s incompatibility with the main electronic control unit. This error will be returned if you install an incompatible user interface control panel on your dishwasher. Check the part’s specifications and order the correct panel to install it on your dishwasher.
|Maytag dishwasher error code 2-1
|A button on the user interface control panel has stuck. Test all the buttons available on the user interface control panel for their response. In case one or more buttons are not responsive, disconnect the appliance from the mains grid, disconnect the wire harness leading to the user interface control panel, and put the door back in place but with the wires disconnected. Do not close the door. Connect the dishwasher to the mains power supply and wait for no less than 7 seconds to allow the electronic control unit to power up. Now, shut the door. In case the main electronic control unit does not detect stuck buttons any longer with the wire harness disconnected, the dishwasher launches the drain pump. If it does, you will want to replace the user control panel. However, odds are high the drain pump won’t start. In this case, it is the main electronic control unit that needs replacing as it continues to detect stuck buttons even though the user control panel is disconnected.
|Maytag dishwasher error code 3-2
|The thermal sensor or OWI is shorted. If you see this error, disconnect the dishwasher machine from the mains grid and inspect the wiring harness linking the electronic control unit and the thermal sensor or optical water indicator. If the fires are damaged or loose, repair, replace, or reconnect them back in place. However, you will have to replace the thermal sensor or optical water indicator in case all the wiring is intact.
|Maytag dishwasher error code 6-2
|Water inlet valve malfunction. Disconnect the dishwasher from the mains network to cut off the power supply. Remove both the bottom front access panel and the toe panel. Inspect the wires connected to the water inlet valve. Any loose wires should be reconnected. If damaged, replace the entire cable harness. If all the wiring is in good condition, use a multimeter and test the water inlet valve resistance. The water inlet valve resistance readings should return around 1,400 ohms. If the resistance exceeds the required parameters, replace the water inlet valve. In case the issue persists, replace the main electronic control unit.
|Maytag dishwasher error code 7-1
|You will see this error when the heating element fails to operate. Check the heating element and replace it if you see any damage. In case the heating element is in order, disconnect the dishwasher from the mains and inspect the wirings connecting the main electronic control unit with the heating element. Once you see any loose wires, reconnect them. Replace the wiring harness if you see it damaged. If the cable harness is fully operational, it is the heating element that needs to be replaced.
|Maytag dishwasher error code 10-3
|This code means your dishwasher experiences a drying fan malfunction. Try disconnecting the appliance from the power network and examine the wiring harness linking the main electronic control unit and the drying fan. If you see any loose wires, reconnect them back in place. If the harness is badly damaged, replace it with a new one. Otherwise, you will have to replace the drying fan assembly.
