The short answer
On an AEG dryer, water around the machine most often comes back to a condensate hose or tank connection, with a cracked or badly seated tank close behind. The maintenance items these machines actually have — the pump filter, the drain path, the sensors and the condenser on a heat-pump dryer — outrank component failure on a machine of this generation. That puts the first move in your hands rather than a technician’s: work the checks below in order and stop at the first one that explains what you are seeing.
What you are seeing
- What this fault looks like, and which observations point somewhere else.
- water in the base of the cabinet with the tank empty
- water under the machine after a cycle
- water running from a condensate hose connection
- drips from the vent duct or at the wall connection
- Not this fault: if the machine stops rather than leaking visibly, read the cycle page
- Not this fault: if the tank behaviour is the complaint, read the condensate page
Ranked causes on this platform
- Ranked for an AEG dryer, which runs a sensor-driven controller that reports a fault code on the display. No measured frequency exists for this address, so the order is platform judgement rather than a share.
- A condensate hose or tank connection — Why: On a condensing machine this is the only plumbing there is, and a hose that was never clipped home leaks every cycle.
- A cracked or badly seated tank — Why: A tank dropped once leaks slowly afterwards, and the water appears under the front of the machine.
- A heat-exchanger door or seal not closed — Why: The exchanger access has to be latched properly; a partly closed one lets condensate escape into the cabinet.
- An internal condensate pump hose — Why: A hose that has come off inside the cabinet puts every cycle of condensate into the base, and it is invisible from outside.
- Another appliance or a plumbing source — Why: A dryer has no water supply, so a puddle beside one very often belongs to the washer or the plumbing next to it.
What to check, in order
- The order follows the ranking above: most likely and cheapest first, nothing needing a meter until everything else is eliminated.
- A condensate hose or tank connection — Because: on a condensing machine this is the only plumbing there is, and a hose that was never clipped home leaks every cycle.
- A cracked or badly seated tank — Because: a tank dropped once leaks slowly afterwards, and the water appears under the front of the machine.
- A heat-exchanger door or seal not closed — Because: the exchanger access has to be latched properly.
Checks you can safely do yourself
- Isolate the appliance before any panel comes off, and stop at the first step that explains the fault.
- Check the tank seat and the hose connection with a dry towel underneath for one cycle. — Tools: towels — Time estimate: one cycle
- Fill the tank at a sink and look for a weep. — Tools: nothing — Time estimate: a few minutes
- Withdraw the exchanger, refit it squarely and confirm the door latches. — Tools: nothing — Time estimate: a quarter of an hour
- Note whether the tank stays dry while water appears underneath, which is what this fault does. — Tools: nothing — Time estimate: one cycle
- Stop condition: Stop there: the next step means metering live terminals or opening a sealed system.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel, because a capacitor can hold a charge after the power is off. Clear lint from the filter, the housing and the duct: accumulated lint around a heat source is the recognised hazard of this appliance class. Never run the machine with a panel off or the door interlock defeated, and never vent it into the room.
When to call a technician
Call a technician when water is inside the cabinet rather than at a hose or tank, when an internal hose has come off, or when the duct has to be re-run to remove a sag. Water in a cabinet containing a heater is a reason to stop using the machine.

What this page does not cover
This page is generalized across every AEG dryer family and model number: no family fault list, no model parts list, and no measured figure from the program warehouse. Where a family- or model-specific page exists it goes deeper, and it should be preferred over this one.
