10 L smart cool-mist tower humidifier with VeSync, Auto Mode, model LUH-M101S-WUS, a pump-fed base chamber, and E1/E2/E7 malfunction codes.
Choose the observed symptom, light, code, app state, or output problem.
Start by raising the mist level and checking the tank. If output is still weak, the OasisMist 1000S manual points to startup delay, blocked air inlets or nozzles, an unlevel surface, detergent residue, the pump cover, Auto Mode reaching its humidity target, or the base not being seated correctly on the tank.
On the OasisMist 1000S, E1, E2, and E7 are documented as humidifier malfunctions, not user-reset codes. Levoit directs owners to Customer Support.
