Problem summary
Water appearing underneath your Samsung WW80 washing machine usually means one of a few wear parts has failed or come loose. The leak may be visible only during a cycle, or you might notice pooling water after the machine has finished. This is a common fault and often fixable without a full machine replacement.
Likely causes
Based on our repair records, the most probable causes are:
Door seal (around 35% of cases)
The rubber gasket that seals the door can perish, crack, or come loose over time. Water escapes into the outer tub and down to the floor. You may also notice water leaking from the door edge during a wash.
Sump hose or connections (around 14% of cases)
The small rubber hose that drains water from the pump area can split, crack, or detach from its connection point. This typically drips from underneath the machine.
Lamp housing or filter cover (around 15% of cases)
Cracks in the lamp housing or a loose or cracked filter cover seal allow water to escape. These are less common but worth checking as part of a visual inspection.
Drain pump failure
If the pump itself is damaged or blocked, water may leak from its seals rather than draining away properly.
What you can try yourself (DIY)
If you're comfortable working around the machine, try this short checklist:
-
Check the door seal – Open the door fully and inspect the rubber gasket all the way round. Look for visible cracks, splits, hardening, or pieces that have come away. If it looks obviously damaged, the seal likely needs replacing.
-
Inspect the sump hose – Tilt or pull the machine forward to access underneath. Look for the rubber hose running from the pump area. Feel along its length and joints for splits or cracks. Press each connection point to make sure it's seated firmly.
-
Check the filter cover and lamp housing – Access these from the front or side depending on your model. Look for cracks and make sure covers are sealed properly.
-
Run a short test cycle – If you've reseated a hose or tightened a cover, run the machine on a short cycle and watch underneath for leaks.
Door seals and sump hoses are wear parts that many confident DIY customers can replace. However, if the pump itself is leaking, or if you find cracks in the plastic tub, professional help is needed.
If you're in Northern Ireland, SMC Services can usually book a repair within 2–3 working days.
When to call SMC Services
Contact us if the seal or hose is visibly damaged and you'd prefer not to replace it yourself, or if your checks don't reveal an obvious cause. If water is leaking from the drum area itself or the pump, a qualified engineer should diagnose it.
