The short answer
For the Blomberg WFTV family of washers, the generic answer is not wrong but it is not ordered for these models. What follows is the order that suits this platform. The useful question is at which point in the cycle the water arrives. Fill, wash, drain and spin each implicate a different part of the machine. Work from the back of the machine forward. Supply connections are under pressure the whole time the taps are open, which makes them both the most likely and the most urgent.
What you observe on these models
- Water appearing only during the drain or spin — The drain hose connection or the pump housing, which only see water under flow.
- A slow stain spreading on the floor over weeks — A weep rather than a leak, usually at a hose washer or a fitting.
- A puddle at the back that is there even when the machine is idle — A supply connection under constant pressure, which is the one leak that never stops on its own.
- NEAR MISS — the drum is full of water at the end of the cycle — That is a drainage failure, not a leak, and it has its own page.
Causes, most likely first on this family
- Tub seal or bearing seal failed — Last on likelihood and highest on cost, which is why every connection on the list is checked before anyone opens a cabinet.
- Pump housing or its seal weeping — Fifth, and it is usually found during a filter inspection rather than by looking for it directly.
- Drain hose connection loose or the standpipe backing up — Fourth, and half of these turn out to be outside the machine entirely, in a waste line that cannot take a washer's discharge rate.
- What moves, and why it moves, on this platform — Two things reorder this list for these models: where the family puts the component, and how much has to come apart to reach it. A cause that is two minutes away on this platform is worth checking before one that is an hour away, even when the second is marginally more likely.
Check in this order, and why
- Fold back the whole door seal and look inside it — Run a finger all the way round the fold. Coins, hair clips and grit collect there and channel water out.
- Run a short cycle and watch each stage — Fill, wash, drain, spin. The stage at which water appears identifies the half of the machine it comes from.
- Dry the floor completely and lay paper down — You cannot judge a leak on a wet floor. Paper shows you exactly where the first drop lands, which is more useful than a puddle.
- Why the order matters more here — Because on this platform the difference in effort between the first check and the last is substantial. A sequence that starts at the accessible end reaches the same conclusion with far less work, and that is the whole reason for ordering it rather than listing it.
Before you open anything
Safety
Switch off at the socket and close the taps first. Have towels ready: a drum that has not drained empties through the filter port all at once, and a wet floor beside a plugged-in appliance is a hazard in itself.
When to call a technician
The line is the cabinet. Filters, hoses, seals, taps, detergent and levelling are yours; pumps, pressure switches, bearings and control boards are not. Call sooner if there is any burning smell or if the machine trips its circuit.

What this page generalizes over
This page covers the Blomberg WFTV washers as a family rather than one model. The models in it are close enough to share a diagnosis, but not identical, so where a detail depends on the individual model — a component position, a part number — it is not stated here. The family pages and the brand-level article linked below give the surrounding context.
