The short answer
A Miele washer left full of water has nearly always blocked at the drain filter behind the front lower door, and on this platform that filter is designed to be opened by the owner. The drain hose routing and the standpipe come next. All three are owner checks. Only a seized pump or a failed drain control is a service call, and both are less common than a loaded filter.
What you observe
- The cycle ends with water still in the drum — It never drained rather than drained slowly.
- Draining has been getting slower for weeks — The filter is loading up. Routine maintenance overdue.
- A hum at the drain phase with nothing moving — The pump is powered but blocked or jammed.
- Water backing up out of the standpipe — Household waste restriction, not the machine.
- NEAR MISS — it drains but will not spin — That is a lock or balance fault, not drainage.
Causes, most likely first on this brand
- Drain filter loaded with lint, coins and grit — First on this platform by design: everything the drum releases is caught here deliberately, in a housing the owner is expected to open. A machine that has never had it cleaned will eventually stop draining.
- Object jammed at the pump impeller — Second, and visible the moment the filter is out. Its signature is an abrupt change between one load and the next rather than a gradual slowing.
- Drain hose kinked, crushed or badly seated — Third: usually caused by pushing the machine back against a wall. Free to correct and easy to overlook.
- Standpipe restricted, or the pump failed — Last. Water backing up out of the standpipe points at the plumbing; a silent pump with a clean filter points at the pump itself.
Check in this order, and why
- Drain the drum through the spout beside the filter door — Must be done first, and it tells you how much water is there.
- Open and clean the drain filter — The top cause on this platform and an owner job.
- Look into the pump housing with the filter out — The impeller is visible; an object shows immediately.
- Straighten the hose and watch the standpipe on a drain — Left until here because it moves the fault out of the machine.
What an owner can safely check
- Open the spout and drain into a shallow tray — Repeat until the water stops. Do this before the filter.
Tools: shallow tray, towelAbout 20 min
- Unscrew the filter, clean it, wipe the seal face — Refit hand-tight with nothing across the sealing surface.
Tools: clothAbout 20 min
- Look into the housing and turn the impeller by hand — Power off. It should turn freely without grinding.
Tools: torchAbout 10 min
- Straighten the drain hose and reseat it in the standpipe — It should enter loosely rather than be rammed down.
About 10 min
- STOP HERE if the pump is silent with a clean filter — Pump and drain-control testing needs a meter.
Before you open anything
Safety
Unplug the washer or switch off its breaker before opening the filter, and close the supply taps. A capacitor can hold a charge after the power is off, and the impeller can start turning if the machine is still live. Drain through the spout before unscrewing the filter, or a full drum will empty onto your floor. Broken glass sometimes reaches the housing, so use a torch and look before you reach in.
When to call a technician
Call when the filter is clean, the impeller turns freely, the hose is correctly routed and the machine still will not empty — the pump or the drain control is then the answer. Call a plumber instead if the standpipe overflows while the machine drains. Call immediately if the breaker trips at the drain phase, or if you smell hot insulation while the pump is humming.

What this page does not cover
This page is written for the brand and the appliance class, not for one family or model line. Where a family- or model-specific page exists for your unit, that page is the more specific answer and you should start there. Deliberately absent: pump and filter part identifiers, hose diameters, high-loop heights and fault-code meanings, all of which differ between the domestic and professional families.
