A code is only meaningful together with the machine showing it — the same digits mean different things on different equipment.
The code
tt
Some LG cabinets hold a water tank inside the fresh food compartment rather than running the dispenser straight off the line, and this code says the machine cannot find it or cannot see it properly in place. Nine times in ten it is exactly what it sounds like — the tank was taken out to be washed and went back a few millimeters short, or a shelf was moved and the tank is no longer sitting where its detent expects. It is the cheapest code on this list to answer.

On the same appliance
What else belongs to the refrigerators
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this appliance can display
The fan over the condenser has stopped turning, and the machine has noticed
The fan that moves cold around the freezer is not turning
The fan feeding the fresh food side has stopped
The sensor reporting the freezer temperature is not making sense
The fresh food compartment's own sensor is not reporting properly
The sensor that decides when to melt the ice off the coil has failed
The machine cannot read the temperature of the room it is standing in
The fan that carries cold to the ice maker has stopped
The ice maker cannot tell whether the cubes are frozen yet
The ice maker's own motor is not turning the harvest
The main board and the display have stopped talking to each other
The refrigerator has found something wrong inside itself and wants a technician

The other ways LG prints this one
tt · Er tt
LG publishes a condition and then every string that can stand for it, and which one your machine shows depends on the panel it was built with — OE, E03 and E21 are one condition on a washer, and Er dS, F dS and r dS are one sensor on different evaporators. They are one page here, so whichever of them you searched for, this is the right page.
Where this appears, and why not to clear it
On the appliance's own display. LG reports errors two ways: machines with a digital display show a code, and the laundry machines without one blink their indicator lights instead. Both are published by the maker and both are on this site. Photograph what the panel shows before cutting the power. On a refrigerator you can also force the last code back onto the display by holding Freezer Temperature and Express Frz together for three seconds — LG documents that, and it is the one thing that makes a first visit more useful. A code that has been reset is information a technician no longer has.
What to do about it
- Find the tank, take it out and put it back firmly until it stops.
- Check nothing is behind it — a jar pushed to the back will hold it a fraction proud.
- Run the dispenser for a few seconds afterwards.
- If the code stays with the tank properly seated, the sensing switch is the repair.
Where this goes next
The job this usually becomes is diagnostic visit, and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call (305) 419-0291 and describe what the panel is doing before booking anything.
