You’re absolutely right — the compressor should not be wet under normal operating conditions. If it is, there’s likely an issue that needs immediate attention.
Check:
Evaporator Drain:
Ensure the drain is not clogged or restricted.
Verify it’s sloped properly for unobstructed drainage.
Check for water backup that might be spilling into the compressor area.
Water Lines in the Machine Room:
Look for leaks or condensation on cold water lines.
Make sure all lines are insulated properly to prevent sweating.
Inspect fittings, valves, and joints for slow leaks.
Compressor Location and Environment:
Is the compressor directly under any drain lines or coils?
Could it be catching drip water from an overhead unit?
Refrigerant Charge or Suction Line Issues:
If the suction line is too cold, (OVERCHARGE) it could cause excessive sweating.
Air Leaks:
Warm humid air entering the equipment can condense on cool surfaces, including the compressor.

Having same issues Tank didn’t fix the problem
Had that once, turns out cx was using distilled water which is not recommended by LG because lacks mineral in water.
Empty water comes in ate 2 minutes off running. Drain tank is empty. Can’t find problem. Water drain connector check and clean.
Error AE
Opened the back and the compressor was wet. Is this a sensor or something or do I have steam, water or both coming into the bottom?
TIA
