Notes
- F37 on a LG dishwasher means: Auto-open door error — the door could not open at the end of the cycle.
- LG uses a single code for this fault across its dishwasher range, so anything you find under F37 applies.
- This fault family has no published equivalent on the other brands listed here yet.
- Work the steps in order. They are arranged so the free checks come before the ones that cost money, which is also the order in which the causes actually occur.
- Clearing the code is not fixing it. Every one of these machines will show the code again on the next cycle if the underlying condition is still there. A code that clears and stays away means the fix worked; a code that clears and comes back means it did not.

Manufacturers document only their own codes, so nobody publishes that second row. It matters more than it looks: a household usually owns two brands over time, and a repair thread that solves your problem is often written about the other one.
Work the checks in order
The steps below are ordered so the free ones come first. That is also the order in which the causes actually occur — the cheap check is cheap because it is the common cause, not despite it.
Start with: Check nothing sits against the door — a cabinet handle, a mat, a bin.
Clearing the code is not the fix
Every machine here will show the code again on the next cycle if the condition that caused it is still present. Two outcomes are worth telling apart:
- the code clears and stays away — the fix worked
- the code clears and returns — it did not, and the next cycle costs you the same diagnosis again
Cutting power for a minute clears the display on nearly all of these. It does not tell you anything about the fault.
When to stop and call someone
A code is a service call when the next step would put you next to something live, pressurised, or holding water above the door line — or when the maker itself says so, which is noted on this page where it applies.
Everything else on this list is a filter, a hose, a latch or a load. Those are worth twenty minutes before anyone charges a call-out fee.
