What an Error Code on Your Appliance Display Means

Modern appliances run self-checks and show an error code when something is outside its normal range. The code doesn’t always name the broken part, but it tells a technician which system to look at first.

Common types of error codes

• Water supply or drain: washers and dishwashers that can’t fill or drain in time.
• Door or lid lock: the appliance can’t confirm the door is closed and locked.
• Temperature sensor: a sensor reading that is too high, too low or missing.
• Heating: an oven, dryer or dishwasher that isn’t heating as expected.
• Control or communication: the control boards can’t talk to each other.

What you can safely check

• Write down the exact code, including any letters.
• Look it up in your owner’s manual or on the manufacturer’s website.
• Try a reset: unplug the appliance or switch off its breaker for one to two minutes.
• Check simple causes: closed water valves, kinked hoses, clogged filters, or a door that isn’t fully shut.

When to call us

Call a technician if the code returns after a reset, or if you notice leaks, a burning smell or sparks. If you smell gas, leave the home and call your gas company first. When you call us, tell us the code so our technician can come prepared.
