Diagnostic mode is a special mode on a Maytag MFT2455ER dishwasher that allows you to run a series of tests to help troubleshoot problems. To put your Maytag MFT2455ER dishwasher in diagnostic mode, follow these steps:
- Make sure the dishwasher is empty.
- Close the door.
- Press and hold the “Start/Cancel” button for 5 seconds.
- Release the “Start/Cancel” button.

Once the dishwasher is in diagnostic mode, you can run a series of tests to help troubleshoot problems. To run a test, press the “Start/Cancel” button and then press the corresponding number on the keypad for the test you want to run. The dishwasher will then run the test and display the results on the LED lights.
