A vented dryer has no drain
A vented dryer has nothing to drain, so a drainage complaint on shared laundry equipment nearly always belongs to something else in the room - the washer beside it, a stacked unit whose washer half is failing, or condensate forming in a long cold vent duct. Identify which machine the water actually comes from before anything else.
What you are seeing
- Water on the floor beneath or beside a dryer.
- Water inside the dryer drum or in the lint area.
- A stacked unit dripping from the washer section above.
- Standing water at a shared floor drain in the room.
- Damp in the duct area behind the machines.
- Not this fault: Water only when the washer beside it runs is that washer's fault, not the dryer's.
- Not this fault: A wet load coming out of the dryer is a drying fault, not a drainage one.
Most likely causes, in Direct Supply order
- Water from the washer beside or above the machine — Why ranked: First in a shared laundry. Stacked and adjacent machines share floors and drains, and the water travels.
- Shared floor drain blocked or backing up — Why ranked: Second: a communal drain serving several washers blocks routinely and the water finds the lowest machine.
- Condensate forming in a long or cold vent duct — Why ranked: Third. A duct running through an unheated space condenses and the water runs back toward the machine.
- Rain or exterior water entering through the vent outlet — Why ranked: Fourth. A damaged or missing outlet hood lets weather straight into the duct.
- A condensing or combination machine in the bank with its own drain — Why ranked: Last, and only where such a machine is fitted - it does have a drain, and it can block like any other.
What to check, in order
- Dry the floor and watch which machine is running when the water returns. — Because: In a room full of machines this is the only reliable way to identify the source.
- Check whether the water appears in the drum or only on the floor. — Because: Water inside the drum points at the duct or a stacked washer above; water on the floor points at a neighbour or the drain.
- Look at the shared floor drain for standing water. — Because: A backing-up communal drain affects everything in the room and is a facility job.
- Ask whether the duct runs through an unheated space. — Because: A cold duct condenses, and the water runs back down toward the machine.
Checks you can do safely
- Dry the floor and mark the wet area, then note which machines run. — N: 1 — Tools: Mop, marker — Time: one cycle
- Look inside the drum and the lint area for water. — N: 2 — Tools: Torch — Time: quick
- Check the shared floor drain for standing water or debris. — N: 3 — Tools: Torch — Time: quick
- Report the source machine and the observation through the facility route. — N: 4 — Tools: None — Time: quick
- Keep the area marked and dry until it has been attended. — N: 5 — Tools: Sign, mop — Time: quick
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Water on a laundry room floor with powered machines is both a slip and a shock hazard - make it safe and report it before investigating. Never work at a machine standing in water. Do not run a machine that has water inside its drum or lint area. Mark and report a wet floor immediately.
When this becomes a service call
Water is inside a dryer drum or lint area. The shared floor drain is backing up. Water appears with no machine running. Water is entering through the vent duct in wet weather.
What this page does not cover
This page covers Direct Supply dryers as installed in shared community laundry rooms. It does not cover in-room ventless and condenser dryers in resident apartments, which do have a condensate path of their own and their own page, and it names no model-specific part. Where a family- or model-specific page exists it supersedes this one.
