Your Bissell steam mop may leak from the back vent due to a clogged filter, overfilling the water tank, or a damaged gasket; check and resolve these issues.
If your Bissell steam mop is leaking from the back vent, you’re not alone. This common issue often stems from clogs, seal failures, or improper use. Let’s explore the causes and solutions to get your mop working like new.
Common Causes of Back Vent Leaks
Mineral Build-Up in Steam Assembly
Hard water leaves mineral deposits that clog the steam assembly. This forces water to escape through the back vent. Distilled water prevents this issue. If you’ve used tap water, you may need to descale the system.
Damaged Water Tank Seal
The rubber gasket between the tank and mop can crack over time. Check for visible damage. A faulty seal allows water to bypass normal channels and leak from the vent.
Overfilled Water Tank
Exceeding the fill line creates excess pressure. The safety vent releases this pressure by leaking. Always fill to the marked level for proper operation.
Step-by-Step Fixes

Before disassembling your mop:
- Verify proper tank seating

2. Clean the Steam Assembly
For mineral deposits:

3. Replace Faulty Parts
Common replacement parts include:
| Part | Cost | Difficulty |
