What E-33 means on a Samsung hood

The E-33 error code on a Samsung hood indicates that the weight sensor's initial HEX value has remained below 14 for a continuous period of 30 seconds while the sensor is actively operating. This sensor is part of the hood's automatic load-detection or ventilation management system, which uses weight-based input to monitor or respond to conditions such as grease accumulation on filters or other load-related variables. When the sensor output falls below the acceptable threshold of HEX 14 and stays there, the control board flags the fault and triggers this code.

The underlying causes generally fall into two categories: a faulty sensor producing an abnormally low signal, or a wiring/connection issue preventing the correct signal from reaching the control board. A weight sensor that has failed internally will output a consistently weak or near-zero value, keeping the HEX reading below the required minimum. Corroded terminals, loose connectors, or damaged wiring harnesses between the sensor and the control board can produce the same symptom by introducing resistance or breaking the signal path.

Because the fault condition must persist for a full 30 seconds before the code triggers, intermittent connection problems may also cause this error. Vibration during hood operation, for example, can cause a marginal connector to drop signal intermittently until the 30-second timer completes. Diagnosing this code requires checking the sensor output signal directly and inspecting the full wiring path between the sensor and the control board before concluding the sensor itself has failed.

Common causes of E-33

  1. 01

    Failed weight sensor

    Part replacement

    The weight sensor itself may have failed internally, causing it to output a signal that falls below the minimum required HEX value of 14. A failed sensor will produce a consistently low or near-zero reading regardless of wiring condition.

  2. 02

    Loose or disconnected wiring connector

    Wiring / connection

    A connector between the weight sensor and the control board that is loose, partially seated, or disconnected can drop the signal below the required threshold. Inspect all connectors along the sensor wiring harness for proper seating and signs of looseness.

  3. 03

    Corroded or damaged wiring harness

    Part replacement

    Corrosion on terminal pins or physical damage to the wiring harness running from the weight sensor to the control board can degrade the signal enough to keep the HEX value below 14. Look for discoloration, melting, or physical breaks in the wire insulation.

  4. 04

    Faulty control board

    Part replacement

    If the sensor and all wiring check out correctly, the control board may not be interpreting the sensor signal properly due to an internal fault. This is a less common cause but should be considered after the sensor and wiring have been ruled out.

Frequently asked questions about E-33

What does E-33 mean on a Samsung hood?
E-33 means the weight sensor in your Samsung hood has been outputting an initial HEX value below 14 for at least 30 consecutive seconds while the sensor is in operation. This indicates the sensor is not producing the minimum required signal level. The fault is typically caused by a defective sensor, a loose connector, or a damaged wiring harness. The hood will need inspection of the sensor and its wiring circuit to resolve the error.
Can I fix E-33 on my Samsung hood myself?
A knowledgeable DIYer can start by inspecting the wiring connectors between the weight sensor and the control board for looseness or corrosion, which requires no parts and may resolve the issue. If the wiring is intact, testing or replacing the weight sensor is the next step, which involves working with electrical components inside the hood. If you are not comfortable with appliance electrical diagnosis, a qualified technician is the safer option.
Is it safe to use my Samsung hood while E-33 is displayed?
Operating the hood with an active E-33 error means the weight sensor is not functioning correctly, which may affect automatic functions that rely on sensor input. The basic ventilation and lighting functions may still work, but any features dependent on weight sensor data could behave unpredictably. It is best to limit use and address the fault promptly rather than relying on the hood in this condition.
How much does it cost to repair a Samsung hood E-33 error?
If the fix is simply reseating a loose connector, there may be no parts cost involved beyond a service call, which typically ranges from $75 to $150. If the weight sensor needs replacement, parts plus labor generally run in the range of $150 to $350 depending on the specific model and local labor rates. A control board replacement, if required, would be at the higher end of repair costs.
Will resetting my Samsung hood clear the E-33 error?
Resetting the hood by cycling the power may temporarily clear the E-33 display, but the code will return if the underlying sensor fault is still present. Because the error requires the low HEX value to persist for 30 seconds before triggering, a reset only delays the fault from reappearing. A lasting fix requires diagnosing and repairing the weight sensor or its wiring circuit.
