The short answer
On Blomberg WFTV washers this symptom narrows faster than it does at brand level, because the construction of this family rules some causes in and others out early. New noise at spin is the one worth taking seriously early, because that is where the loads on the machine are highest and where a small fault becomes a large one. If the machine was installed or moved recently, check the transit bolts before you check anything mechanical.
What you observe on these models
- A metallic scraping through the whole cycle — Something is between the drum and the tub, and it is there whether the drum is fast or slow.
- A humming that does not change when the drum stops — Not the drum at all; something that runs independently of rotation.
- Banging and walking across the floor during spin — The machine is out of balance, either from the load or from its own footing.
- NEAR MISS — the noise comes with water on the floor — Check the leak page first. A pump housing that has been forced can be both noisy and wet.
Causes, most likely first on this family
- Load unbalanced or the machine not level — First on the list because it costs nothing to test — redistribute the load by hand and re-run the spin.
- Drum bearings worn — Last on likelihood, and it is the one entry here where the repair cost can approach the value of the machine.
- Drive belt worn, glazed or slipping — Fifth: a belt that has glazed squeals as the drum accelerates and settles once it is up to speed, which is a very distinctive pattern.
- Where this order differs from the brand-generic page — On this family the access route decides the sequence. The cause that moves up is the one reachable without removing a panel on these models, and the cause that moves down is the one that needs the cabinet opened — so the ranking here is ordered by what this platform lets you confirm first, not only by raw likelihood.
Check in this order, and why
- Rock the cabinet by its corners — Any movement means a foot is not carrying weight, and an unloaded foot turns ordinary vibration into banging.
- Stop the machine mid-spin and redistribute the load by hand — If the next spin is quiet, the load was the story and no part has failed.
- Identify which part of the cycle the noise belongs to — Wash only, spin only, drain only, or throughout. Each of those four maps to a different short list.
- How to work this list on this platform — Take the steps in order and stop at the first that gives a clear answer. The sequence is built so that the cheap eliminations happen before any disassembly, which is specifically what the construction of these models rewards.
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
What this page generalizes over is the set of Blomberg washer models carrying the WFTV prefix. They share a platform and therefore a fault pattern; they do not share every part. Anything that varies model by model is deliberately absent, and the pages linked below give both the wider and the narrower view.
