The short answer for the F models
On the AEG-Electrolux F dishwasher models, water that will not leave the machine leads somewhere the brand-generic article does not put first — the sink plumbing itself is blocked. The brand-generic ordering opens instead with this: debris in the filter and the sump. It moves down behind the lead here, because this family is a short run on a common stem, so its behaviour is consistent in a way the brand as a whole is not.
What you observe on these models
- It started right after work was done at the sink — A new disposal, a new trap or a moved hose is the most common trigger there is.
- Water comes back into the machine after it has drained — That is siphoning or a backflow, not a failure to pump.
- A pool of water in the bottom at the end of every cycle — Enough to cover the sump and the filter, and it does not go down on its own.
- NEAR MISS — water is on the floor rather than in the machine — That is a leak, and the leak page is the one to read.
Causes, most likely first on the F family
- The sink plumbing itself is blocked — The machine shares its drain with the sink. Ranked first on the F models.
- Debris in the filter and the sump — Labels, seeds, bones and broken glass collect exactly where the water leaves. Second.
- The waste connection behind the joinery — A built-in machine drains through a hose clipped up behind the cabinet into a spigot on the sink trap. Third.
- The drain pump has failed — Every other item here is cheaper, faster and more often the answer, and a silent pump is the only real evidence for this one. Last, and that is the point of the order.
- Body: The spine for the F family records 6 model codes built on a common stem — a short run rather than a long one, which is why a single ordering covers all of them. Where this departs from the brand-generic ordering: the cause that moves up on these models is this one — the sink plumbing itself is blocked — and the brand-generic lead moves down behind it.
Check in this order on the F models, and why
- Open the cupboard next to the machine and find the drain spigot — First: The whole drain path on a built-in machine is hidden, so it has to be looked at deliberately rather than glanced at.
- Fill the sink and watch how fast it empties — Second: If the sink is slow, the machine was never going to drain, and you have just saved yourself the whole rest of the list.
- Pull the machine out far enough to see the drain hose run. Get a second person before you pull the cabinet out or tilt it. — Third: Look for a crush behind the cabinet, a missing high loop and a hose pushed too far into the standpipe.
Before you open anything
Safety
Isolate the machine at the breaker and close the supply valve before touching a hose or a panel: a capacitor holds its charge past the switch, and the sump still holds water when the cycle has finished. Gloves on — that water is caustic — and never tape or wedge the door catch to watch a cycle.

When to call a technician
Call when the filter and sump are clean, the sink drains freely, the hose runs without a crush and has a high loop, and the machine still finishes with water in it — that puts the fault at the valve or the pump, both under the sump. Call rather than continue if a glass has broken in the machine and you can see fragments in the sump, because clearing those blind is how people get cut. On the F models the line sits where the check stops being one you can make from outside the cabinet.
