The display is blinking something at you. This page tells you what it usually means, sorted by machine and brand, so you can call with the right word. A code narrows the search; it does not name the part. That still takes a meter at your door, and the $99 for that diagnosis is inside the written repair price if you go ahead.

An error code is the machine’s own diagnosis, and it is worth more than any description of the symptom. It tells us which circuit the control board gave up on — drain, fill, heat, door, motor, a sensor — and that tells us what to load on the van before we leave W Montague Ave. Photograph it as soon as you see it, because many codes clear when you cut power, and what remains is a story about damp towels. What a code does not do is name the failed part. A drain code covers a clogged filter, a dead pump, a kinked hose or a board that can’t hear the pump. Only a meter separates those.
Here is how a code becomes a number. You call or book online with the code and the brand. We arrive with the likely parts, test the circuit the code points to, and confirm the actual failure rather than the first thing on the list. Then we write one price. The $99 diagnostic is inside that number; approve it and you never pay the $99 separately. Decline and $99 is the whole bill, no pressure attached. Book online and up to $20 comes off the repair, never off the diagnostic. Most code-driven repairs close the same visit because we knew what to bring, and every one leaves with a full test cycle and a written warranty.

Usually not. Cutting power clears the display, not the cause, and the code returns the next time the machine reaches the step that failed. Photograph the code before you reset so we have it, then run the machine once more if it is safe to do so. A code that does not come back after a single reset may have been a one-time event, such as a Lowcountry storm surge tripping a board.
No, and we would rather not guess. A drain code, for example, can be a filter, a pump, a hose or a board, and those are different repairs. The code tells us what to bring so the visit closes in one trip. The technician tests the circuit, names the part and writes one number, with the $99 diagnostic already inside it. Decline and $99 is the whole bill.
Hurricane-season surges and brownouts are hard on inverter compressors and control boards. A brief voltage drop can trip a compressor lock or power-failure code even when nothing has failed; a real surge can damage the board. If the unit cools normally after the code clears, note the date. If codes repeat or cooling suffers, we test the board and inverter and usually recommend a surge protector.
Because the dryer measures its own airflow and temperature, and a blocked vent looks like a heating problem from inside the drum. In humid climates lint packs into felt, and in raised houses with long crawlspace vent runs it happens fast. Clearing the vent fixes the code and protects the thermal fuse and element; ignoring it leads to a no-heat call a season later.
LG, Samsung and Bosch post the most specific codes; Frigidaire and Electrolux are close behind. Whirlpool, Maytag and KitchenAid mix display codes with blink patterns on the lights, and GE ranges post clear F-codes while GE refrigerators mostly show a power-failure flag. Older machines and many ice makers post nothing at all. In every case the code is a starting point and the meter finishes the job.
