# Dishwasher error code F37

### What F37 means on this make

Several LG machines finish by opening the door a few inches on their own, which lets the steam out and finishes the drying without a heater. A small actuator does it, and this code says it did not happen. The machine is entirely usable with the door opened by hand — which is what everybody did before this feature existed — so it is a repair to book rather than to rush.

### The other ways LG prints this one

F37 · F 37

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

- Open the door yourself at the end of the cycle; the drying will be nearly as good.
- Check nothing physically blocks the door — a mat, a bin, a cabinet handle opposite.
- Cycle the power at the breaker.
- Book it when convenient.

### Where this goes next

The job this usually becomes is [diagnostic visit](/services/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](tel:+13054190291) and describe what the panel is doing before booking anything.
