The short answer
Standing water left in the bottom of the BD line at the end of a cycle is nearly always a blockage rather than a dead pump. The filter, the pump impeller and the drain path to the sink account for most of it, and all three are reachable without tools. A pump that is genuinely electrically dead is the least common of the four causes, not the first. Because only one model number carries the BD name, nothing below needs a variant caveat.
What you observe on these models
- A rattle or a grinding note during the drain phase — Something hard in the impeller — glass, a fruit stone, a label — which stops the pump moving water long before it stops the motor turning.
- Drain works after the filter is cleaned, then fails again in a week — The filter is catching what a partly blocked sump is failing to pass; cleaning treats the symptom each time.
- Cycle stops early and the panel will not clear — Many machines abandon the cycle when the water has not gone, so a drain fault presents as a stalled cycle rather than as standing water.
- Water standing in the sump at the end of every cycle — An inch or so left over the filter, usually cloudy, with dishes that came out mostly clean.
- NEAR MISS — the tub is empty but dishes are wet — That is a drying complaint, not a drainage one, and it belongs on a different page.
Causes, most likely first on the BD line
- Blocked filter and sump screen — First, and the cheapest to rule out. The filter is the one part of the drain path designed to catch things, so it is the first thing to fill; on a machine used daily it can choke in weeks rather than years.
- Drain pump impeller jammed — Next most likely on these models. A jammed impeller gives the classic signature — the machine hums for the full drain period and the water level never falls.
- Kinked, looped or blocked drain hose — Third — worth checking once the two above are clean. Grease sets inside a drain hose over years and narrows it from the inside, which produces a drain that works slowly and then not at all.
Check in this order, and why
- Take the filter out and look at the sump under it — Twist it free, rinse it, and put a hand into the well beneath — most of what blocks a drain is sitting there and comes out with a finger.
- Reach the impeller through the sump opening — With the power off, turn the impeller by hand. It should spin freely. A hard stop is an object, and the object is usually visible once the light is right.
- Follow the drain hose from the machine to the waste — Look for a kink behind the cabinet, check it still rises to a high loop, and squeeze along its length for the hard spot that grease leaves.
Before you open anything
Safety
Switch the machine off at its breaker before a panel comes off or a hand goes into the sump — a capacitor can hold a charge after the power is off. Shut the supply valve under the sink before disturbing a fitting, and never wedge the door interlock to watch a wash run.

When to call a technician
If the filter is clean, the impeller turns freely and the hose is clear, the next step is electrical testing of the pump and its circuit, and that is a service call on the BD line. Call straight away if water is backing up into the sink as well as standing in the machine — that is a house drain problem and it will not be cured by anything done to the appliance.
