Match your symptom to narrow down the likely cause before calling us.
These checks are safe for homeowners. Do not attempt to open sealed refrigerant systems, touch electrical components behind access panels, or work on gas lines — always call a licensed technician for those.
Unplug the washer from the wall for 5 full minutes, then plug back in. This clears the control board memory and resets all sensors. Many transient errors — caused by power fluctuations, momentary sensor glitches, or a stuck door lock — clear with a reset and don't return.
Error codes differ significantly between brands and even between model generations. Search "[your brand] [your model number] error code [code letters]" for the manufacturer's exact definition. The model number is usually on a sticker inside the door frame or on the back panel.
For any code related to drainage (F21, OE, E3, Ld), the first thing to do is clean the pump filter. On front-loaders it's at the bottom front behind a small panel. Have towels ready — water will pour out when you open it. Clean the filter, reinstall, and run again.
Does it appear at the start of the cycle (fill codes), during agitation (motor codes), at the end (drain/spin codes)? The timing tells you which system is at fault and is the most useful information to give a technician.
F21 means the washer took longer than 4 minutes to drain during the drain phase. The first thing to check is the pump filter — on front-loaders it's in the bottom front access panel. If the filter is clear, the drain hose may be kinked or the drain pump motor has failed. F21 is one of the most common washer error codes we see in Charlotte.
LF stands for "Long Fill" — the washer tried to fill but the water level didn't reach the expected level within the allotted time. Common causes: supply valve partially closed, kinked inlet hose, clogged inlet screens, or low house water pressure. Start by checking the supply valves are fully open and cleaning the small screens inside the inlet connections.
Yes — unplug the machine for 5 minutes, then plug back in. This clears the control board and resets all fault memories. If the code reappears on the next cycle, the underlying issue hasn't been resolved and the machine is correctly identifying a real failure. Repeated resets without fixing the root cause wear the machine further.
No — error codes are designed to help diagnose specific, repairable component failures. Most error codes point to a single part (pump, valve, lid switch, actuator) that can be replaced at reasonable cost. The presence of an error code is actually helpful: it narrows down what a technician needs to fix and often means a same-day repair is possible.
