Samsung Oven: not functioning due to empty water tank sensor issue
What is this symptom?
Is your Samsung oven displaying a 'water tank empty' message even when the reservoir is full? This issue can disrupt steam-related functions like steam baking and roasting. Common causes include a faulty water reservoir sensor or pump assembly, which may prevent your oven from operating correctly.
Important Tips for Samsung Models
- Common issue with steam oven water reservoir sensors mis‑reading water level even when water is present, sometimes requiring part replacement
Possible Causes
Faulty water reservoir sensor or pump assembly
How to Identify: Oven repeatedly shows ‘water drawer empty’ error even when properly filled; reservoir must be repeatedly removed and reinserted for temporary resolution
Part: Water reservoir sensor / pump
Control board or firmware mis‑read error
How to Identify: Error persists even after hardware checks; software reset does not clear and steam functions disabled
Part: Control board / software
DIY Solutions
Reseat and clean the water reservoir
- Turn off the oven and ensure it is cool
- Fill the reservoir to manufacturer‑specified level (usually ~650 ml/22 oz) and ensure cap is securely closed
- Remove and reinsert the reservoir several times until it clicks into place
- Try running the steam function again
Inspect reservoir tubes for damage
- Turn off and cool oven
- Pull out water reservoir and inspect small tubes at end for cracks or breaks
- If damaged, note exact tube size/shape for replacement part order
- Avoid bending or stressing reservoir during handling
