What Are Diagnostic Codes?
Think of your KitchenAid dishwasher as a super-efficient communicator. Instead of leaving you guessing when something goes wrong (or even when it’s just a minor issue), it uses diagnostic codes to tell you exactly what needs attention. These are usually displayed as combinations of letters and numbers on the control panel.
Though they might look intimidating at first don’t worry they’re super handy when it comes to pinpointing issues and fixing them quickly. It’s kind of like having a secret handshake with your dishwasher!

How to Access Diagnostic Codes on Your KitchenAid Dishwasher
Before we jump into what the codes mean, you first need to access them. Here’s how you can do it:
- Turn off the dishwasher completely (make sure there’s no active cycle running).
- Enter diagnostic mode. On many models, this involves pressing a specific combination of buttons. The most common sequence is:
- Press Heated Dry > Normal > Heated Dry > Normal within five seconds.
- The control panel will light up like New Year’s Eve, and voilà, the codes will display. These codes give you the clues to troubleshoot like a pro!
💡 Pro Tip: Always check your dishwasher’s user manual for model-specific instructions button sequences can vary depending on the model.
