The short answer
A leaking BFLW machine is telling you where to look by when it leaks. Water during fill is the supply side; water during drain is the hose or the pump; water that appears at any time is the door seal or an overflow.
What you observe
- Water appears only while the machine empties — The drain hose, its connection or the standpipe backing up.
- Water over the top of the standpipe or sink — The house drain cannot take what the machine delivers. The machine is healthy.
- Water or foam at the detergent drawer — A blocked or overfilled drawer backing up. It reads as a leak and is usually a dosing or a cleaning matter.
- A slow puddle even when the machine is not running — A tap and a fitting that weeps under standing pressure.
Causes, most likely first
- An inlet hose or its washer at either end — First on this family. These machines are connected and disconnected far more often than a plumbed-in one, and the rubber washer inside the fitting is what pays for it.
- The drain hose connection or its route — Second. A hose that has been crushed behind a foot, or one that is no longer secured where it discharges, puts water on the floor only while the pump runs.
- The tub, its seal or an internal hose — Last. It is the expensive cause and the least likely on this family - and on a machine this size it is usually a replacement decision rather than a repair.
- The pump housing, its seal or the filter cover — A filter cover that was not seated after cleaning leaks at every drain. It is worth checking early precisely because it is self-inflicted and easy to miss.
Check in this order
- Wipe the door or lid seal and look along it for a trapped garment — Explains a leak that happens on one wash and not the next without any part being at fault.
- Dry everything and run a cycle, noting exactly when water appears — Fill, wash, drain and idle are four different faults.
- Check the pump filter cover is fully seated — Early, because it is free, and because a cover left loose after a cleaning is a very common self-inflicted leak.
- Watch the standpipe while the machine drains — Last of the free checks, and it decides whether this is an appliance job at all.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Dry the floor before moving the machine: a compact washer on a wet floor slides rather than walks, and it is heavier than it looks when the drum still holds water.

When to call
Call straight away if water is reaching a socket, a run of flooring or a floor below. Call sooner rather than later if the leak is under mains pressure at an inlet fitting, because that one does not stop when the machine does - shut the taps in the meantime.
