The NOMA dehumidifier model 043-5794-8 may stop at 56% humidity instead of the set level of 35% due to a faulty humidity sensor. A defective sensor can give inaccurate readings, causing the unit to shut off prematurely because it incorrectly senses that the desired humidity level has been reached.

The NOMA air conditioner 043-5794-8 may smell like onions due to the buildup of mold, mildew, bacteria, or other organic materials on the internal components such as the evaporator coil or filter. When moisture combines with dust and organic particles, it can create odors that resemble onions or other strong smells. Cleaning or replacing the air filter, and cleaning the evaporator coils and drainage system, may help eliminate the odor.

To properly drain water from the NOMA 043-5794-8 dehumidifier using the hose:

1. Attach a clean drain hose to the drain outlet on the back of the unit.
2. Ensure the hose is securely connected and not kinked or blocked.
3. Position the other end of the hose to flow into a suitable drain at a lower level, using gravity for drainage.

Possible causes of the NOMA 043-5794-8 unit not collecting water after two months of use include:

1. Clogged or dirty humidity sensor – cleaning it with canned air has resolved the issue for some users.
2. Faulty or malfunctioning internal water pump – even if it runs, it may not be moving water properly.
3. Blocked or improperly connected drain hose – should be clean and correctly installed.
4. Dirty filters – back filter and filter near the water drawer should be clean.
5. Electrical issues – problems with wire harness connectors to the pressure switch or control unit.
6. Faulty inlet valve – may not be shutting off or operating properly.

Cleaning the sensor and filters is a good first step. If the issue persists, further inspection of components like the pump, wiring, and inlet valve may be needed.
