Samsung Microwave code **E-33** is associated with **under-weight error**. The display identifies the system or condition the control detected, but it does not by itself prove which individual part should be replaced. The useful diagnostic value of the code is the subsystem it identifies. A good repair process confirms the symptom, checks the accessible external conditions, and then follows the model-specific circuit only if the display returns. The recorded display form is **E-33**. Search normalization stores it as **E33** while preserving the characters a homeowner actually sees.
Content status: Verified
Under-weight error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so E33 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Important safety warning. Do not remove the microwave outer cabinet. High-voltage components can retain dangerous energy even after the appliance is unplugged. Do not bypass a safety device merely to see whether E-33 disappears.
If the code returns after the documented basic checks, request model-specific diagnosis of the affected subsystem. A repeatable E-33 event is more useful diagnostically than repeated resets, because it shows when the under-weight error check is failing.

Under-weight error.
Resetting can clear a temporary state, not a persistent issue. If **E-33** comes back, preserve the code and move to the safe checks or model-specific service path.
Short owner-accessible checks may be reasonable when the appliance is safe. Persistent **E-33**, worsening performance, or any electrical/water/heat hazard is a reason to stop use.
No. **E-33** tells you which condition or check the control detected. The same display can result from the named component, its wiring, a connector, a supply/airflow/water condition, or the control that reads it.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Microwave E-33** separate from same-looking codes used by other Samsung appliance families.
