Error Code Home explains what the error codes on your home appliances, HVAC systems, and water heaters mean, and how to fix them step by step.
When a washer flashes “UE”, a mini-split blinks green, or a tankless water heater shows code 11, most answers online tell you what is wrong but not what to do next. This site was built to fill that gap.
What you will find here
- The meaning of each error code, organized by brand and model
- Step-by-step fixes that are safe to do yourself
- The parts that most often cause each problem
- Clear guidance on when to stop and call a licensed technician

How we write and check our guides
- Every guide is based on the manufacturer’s official manuals and service information.
- Common fixes are cross-checked against real owner experiences.
- Guides are updated when manufacturers change codes or models.
- We never recommend unsafe DIY work. Gas, high-voltage electrical, and refrigerant repairs must be done by licensed professionals.
Safety first
Always turn off the power, gas, or water supply before checking any appliance. If a step involves gas lines, wiring, or refrigerant, or you are unsure at any point, contact a licensed technician.
