Miele W1 Will Not Drain in Bayview Hill

The call

Bayview Hill, a Miele W1 about seven years old, stopped partway through a cycle with a full drum of water and a locked door. The owner had found the drain filter behind the lower panel, opened it, and drained the machine manually — which is exactly right and saved us the messiest part of the job.

What they had not managed was getting the machine to complete a cycle afterwards. It would fill, wash, then stall at the drain stage again.

They asked a reasonable question on the phone: at seven years, was this machine worth fixing? On a mid-range washer that is a fair conversation. On a Miele it is not really a question — these are engineered for roughly twenty years of service, so seven is barely a third of the way through.

Diagnosis

A Miele that will not drain has a short list of causes, and the most common one by a wide margin is something in the pump.

• Drain filter clear — the owner had already done that properly
• Drain hose unobstructed and correctly routed
• Pump attempting to run, audible, but moving almost no water
• No leak detected, Waterproof System not tripped

Removing the pump housing produced the answer: an underwire from a bra, wrapped around the impeller shaft and jammed against the housing wall. It is one of the two or three things we find in pumps most often, along with coins and hairpins.

The impeller had light scoring but no chipping. That distinction matters — a scored impeller still moves water at specification, a chipped one does not.

The fix

The underwire came out, the housing was cleaned, and the impeller was inspected carefully under light before being refitted rather than replaced. We do not replace parts that test fine, even when replacing them would be easier to justify on an invoice.

What we did replace was the pump housing seal, which had been disturbed during removal and was showing its age. On a Miele we fit the factory part without exception: these machines run their own diagnostics and expect components with specific characteristics, and a third-party seal on a pressurised housing is not a place to save $20.

Then a full cycle — fill, wash, drain, spin — with the drain timed against specification. Fifty-five minutes on site.

Outcome

Working normally, and the owner now knows where the filter is and how often to check it.

I assumed a seven-year-old machine was on its way out. You told me it was a third of the way through its life and charged me for a seal.

Two things worth generalising from this job:

Check the drain filter before you call anyone. On a Miele it is behind a small door at the bottom front, designed to be opened by hand, and it is the single most common cause of a no-drain fault. If clearing it fixes the problem, you have saved yourself a service call.

Age means something different on a Miele. We repair these units at ages where we would be recommending replacement on a mass-market machine, and we say so plainly rather than letting someone replace an appliance with thirteen years left in it.
