Quick answer
Possible leak on Floor Protect models; otherwise control reset may be required.
Model compatibility: GE reuses codes across series and model years, so 999 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Possible leak on Floor Protect models; otherwise control reset may be required.
Signs
Symptoms you may notice

Why it happens
Possible causes
Unstable power or an internal control fault after external wiring is verified.
Water reaching a leak/overflow sensing area.
A stuck inlet valve or abnormal fill condition.
An electronic board that is not reading or exchanging data correctly.
A loose low-voltage harness or communication connector.
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Check visible hoses and connections for obvious drips without removing internal panels.
Wipe the control surface dry if moisture or residue could be affecting touch inputs.
Use one controlled power reset; if the same code returns, avoid repeated resets that hide the failure pattern.
Dry any external spill and confirm whether the code returns before assuming the leak sensor itself has failed.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
