What E3300 Means
Thermador publishes E3300 alongside E3400 under one description: water is not getting into the machine the way the filling system expects. Where E3200 says the level fell short, this pair says the inflow itself is being obstructed or is not happening at all.
Common Causes of E3300
- An inlet hose kinked, pinched or damaged
- A supply valve closed or only cracked open
- An obstruction in the filling system the control cannot clear by itself
🔧 One Safe Check You Can Try
Check the inlet hose end to end for a kink or visible damage, and confirm the supply valve is open. That is the whole of Thermador’s published homeowner step for this number.
⚠ Why You Shouldn't Go Further Than That
- Once the hose and valve check out, the remaining parts of the filling system are inside the machine and behind the water connection.
- Running cycle after cycle against a blocked inflow puts the fill valve and pump through work they are not achieving anything with.
