Decode the codes your appliance is showing — what they usually mean, what to check first, and when the code points to a repair a homeowner should not attempt.

Modern appliances announce most failures with an error code on the display or a blink pattern on a status light. These codes are a diagnostic starting point — they tell you which subsystem the appliance's control board thinks has failed, not the exact root cause. An LG washer 'OE' code means 'water not draining' — which could be a clogged filter (free to fix), a kinked hose (free to fix), or a failed drain pump (a $200–$350 repair). The code narrows the search; it doesn't finish it.
Our error-code guides cover the most common codes on major US brands — Samsung, LG, Whirlpool, Bosch, GE — and walk through the likely causes in order from cheapest to most expensive. Wherever it's safe to check something yourself before calling a technician, we say so. When the code points to refrigerant, gas, or high-voltage components, we say to stop and call a qualified pro.
If your error code isn't listed yet, send it to us through the contact page and we'll prioritize adding it.
