The short answer
The WAP family runs its detergent drawer over the top of the tub, so an overdosed wash foams back through the drawer and leaves water at the front that looks exactly like a seal leak. Dose first, diagnose second.
Symptoms on this family
- Water tracking along the floor from behind to the front — The source is at the back and the destination is at the front, which is why the puddle position misleads so often.
- Water on the floor directly under the door after a wash — The classic door-seal position: the water arrives during the wash and stops when the drum does.
- NEAR MISS - condensation under a machine in a cold room — A cold cabinet in a warm humid room makes its own water and no plumbing is involved.
- Damp inside the door seal fold with grit in it — The early stage of a seal leak, and the point at which cleaning the fold still fixes it.
- NEAR MISS - a few drops from the seal when the door opens — Normal on a front-loading machine: the seal holds a little water by design and it runs out when the door swings.
Causes, most likely first on this family
- Tub or bellows split — Last, and rare. It is the only cause on this list that needs the machine opened, and everything above it produces the same wet floor.
- Door seal torn, folded or holding debris — First on this family: the fold at the bottom of the seal collects grit and hair, and that is exactly where the rubber wears through.
- Drawer housing blocked with detergent residue — Water backs up out of the drawer because the path into the tub has silted, and it presents identically to overdosing.
- Pump housing or filter seat not sealing — Very often follows a filter clean where the cap went back cross-threaded or without its seal seated.
The diagnostic order for these models
- Note which step of the cycle the water appears on — Fill, wash and drain implicate different components, so the timing is worth more than the location.
- Feel the inlet hose unions at the taps with a dry tissue — A weep under mains pressure shows on tissue before it shows on the floor.
- Watch a fill with the drawer open — Foam backing up is visible instantly, and it separates a dosing problem from a machine problem in one cycle.
- Open the filter and re-seat the cap properly — Worth doing after any filter clean, because a cross-threaded cap leaks on every drain from then on.
What to do before you start
Safety
Power off at the breaker before any access panel is lifted. Water on a kitchen floor beside a machine that is still plugged in is the hazard here, far more than anything inside the cabinet.

When to stop and book a visit
Stop and call if the machine has already been part-dismantled and will not go back to a known state. A half-assembled drum machine is the one situation where a service call actually gets cheaper by being made earlier.
