Samsung Hood Error Code E-33

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.

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.

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.

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.

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.
