What this usually turns out to be
A leaking washer is usually leaking from the door seal, a hose connection or the detergent drawer, and the stage of the cycle at which the water appears tells you which. Overdosed detergent is a more common cause than any failed part. On the BAMFC models the door seal has a folded lip that traps grit and coins, which is why the seal check on this family means running a finger right into the fold.
How the leak presents
- Water appears only at the drain stage — That points at the drain hose, its clamp or the pump filter seal.
- A slow damp patch under the machine — A weeping connection or the filter seal. It does far more damage than a dramatic leak because it goes unnoticed.
- Water appears only on spin — Often the sump hose or a split tub seal under pressure, and it usually needs the cabinet open.
- NEAR MISS — Water in the drum that will not drain away — That is a drainage fault, and the drainage page covers it.
Causes, most likely first
- Too much detergent or the wrong product — A rinse cycle with no detergent at all settles it for the price of one cycle. It leads on the BAMFC models because it explains more leaks than anything below it and it costs nothing to correct. That is the change from the brand-wide order: on the BAMFC models too much detergent or the wrong product comes ahead of the door seal or bellows.
- The door seal or bellows — The rubber bellows on a front loader traps grit, coins and hair in its folds, and those wear a hole in the lowest part of the fold where water sits.
- Inlet or drain hose connections — The drain hose and its clamp leak only at the drain stage, which is the clue that separates them.
- The pump filter seal or housing — A filter that has been cleared and not refitted squarely, or whose seal has perished, weeps at the bottom front of the machine.
- The detergent drawer or its housing — It is common, it is entirely owner-fixable, and it is frequently mistaken for a door seal leak.
The order the checks belong in
- First — run a rinse cycle with no detergent — If the machine stays dry, foam was the cause and nothing is broken. It is the cheapest decisive test on the page and it removes the most common cause. Each check removes a source, starting with the free ones and ending where the cabinet has to come apart.
- Second — run a finger right into the fold of the door seal — Pull the fold open all the way round and look for grit, coins and a small split at the lowest point. That is where these seals fail and it is invisible from the front.
- Third — check the inlet and drain connections with a dry tissue — With the machine pulled out, wipe each fitting dry and run a tissue around it. Damp at an inlet means mains pressure is escaping and the taps should be shut now.
- Fourth — check the pump filter is seated squarely — If the leak started after the filter was cleared, take it out, clean the thread and the seal and refit it properly. This is the most easily fixed leak on the machine.
Before you open anything
Safety
Switch the washer off at the socket or its breaker and close both supply taps before any panel comes off or any hose is disturbed. A capacitor in the control can hold a charge after the power is off, and the drum can coast for a long time after a spin. Never reach into a moving drum or defeat the door lock on a front loader — it holds water as well as a door. A loaded machine is extremely heavy, so drain it before moving it.
Where the owner job ends
Book with the pattern: which stage leaks, whether the water is soapy, and where it appears. That is usually enough to identify the source before the machine is moved.
