Understanding Appliance Error Codes: What They Mean and When to Call for Help

Have you ever seen an error code flashing on your dishwasher, washing machine, or oven and wondered what it actually means? As your local appliance experts, we’re here to help you make sense of these codes so you know when you can fix things yourself—and when it’s time to call in the pros.

Why Do Appliances Show Error Codes?

Modern appliances from are packed with sensors and electronics that monitor everything from water flow to temperature. When something’s wrong, these sensors trigger an error code to help you (and us) diagnose the problem.

What Do Error Codes Usually Indicate?

  • Simple issues: A blocked filter, an unclosed door, or a kinked hose.
  • Serious problems: Faulty sensors, control board failures, or motor problems.
  • Safety shut-offs: Designed to prevent water leaks, overheating, or electrical hazards.

When You Can Fix It Yourself

We recommend trying these easy steps before calling for help:

  • Reset the appliance: Unplug for a minute, then restart.
  • Check water supply: Ensure hoses aren’t kinked or valves closed.
  • Clean filters or drains: Blockages are a common culprit.
