The short answer
The WM family is a front-loading washer platform sold by Blomberg, and the models in the table below share the build that makes these faults behave alike. The dominant complaint is water left in the drum.
Problems on these models
- Water left in the drum and a door that will not open — The filter behind the front hatch comes first; the pump itself is rarely what failed. See that page. — Slug: blomberg-blomberg-washer-wm-washer-drainage-failure
- Water at the front, from the drawer, or behind the machine — Where it appears first separates a door seal from a hose connection. See that page. — Slug: blomberg-blomberg-washer-wm-washer-water-leak
- Rumble at spin, clinking at low speed, or banging — Which part of the cycle is noisy names the part: spin points at bearings, drain at the pump. See that page. — Slug: blomberg-blomberg-washer-wm-washer-abnormal-noise
- The cycle stalls, repeats a spin, or never finishes — Note the step it stops at: drain, fill and spin each point somewhere different. See that page. — Slug: blomberg-blomberg-washer-wm-washer-cycle-fault
- Dead panel, or a lit panel that will not begin — Prove the supply, then listen for the door lock to click home. See that page. — Slug: blomberg-blomberg-washer-wm-washer-wont-start
Problem classes by frequency
- Water left in the drum — Most reported on this family: what these models are called out for most, and the filter explains the bulk of it.
- Water on the floor — Next, the door seal takes the wear on a front-loading build.
- A washer that has become noisy — Next, arrives with age, and the pump filter catches the cheap causes early.
- A cycle that stalls, restarts or never finishes — Next, usually a symptom of one of the faults above rather than a fault in itself.
- A washer that will not start — Least reported here: most often the door lock or the socket behind the machine.

What is owner-fixable
The pump filter, the door seal, the drawer, the levelling feet and the hose connections are all owner work from outside the cabinet. The drum bearing, the motor and the control are service work, and a bearing here is usually a replacement decision.
