The answer first
Where the brand-generic page treats the fill hoses as a single item, the BWDB line deserves more care: the models listed in the table on this page sit close to the wall and the hose bends tightly behind the cabinet, so a split at the crease is common on this line and rare elsewhere in the brand.
What you are seeing
- The floor is wet behind the machine — Rear water is supply side: the inlet hose washers, the tap connections or a split in the hose where it bends.
- Water only appears when the machine drains — A drain-side joint or the pump housing. It leaks under pressure and is dry the rest of the time, which is why it is easy to miss. This is where the BWDB line differs from the brand’s other lines.
- The puddle smells of detergent — Wash water rather than clean supply water, which rules out the inlet side immediately.
- The leak only happens on the rinse — A rinse fills to a higher level than the wash on many programmes, so a marginal seal shows there and nowhere else.
- The leak stopped after the machine was moved — A leak that comes and goes with the machine’s position is a hose under strain.
- NEAR MISS — condensation under a machine in a cold room — A cold garage or an unheated utility room produces a film of water under the cabinet that is not a leak at all.
- NEAR MISS — the water is coming from the sink or the standpipe — A shared waste that backs up puts water on the floor while the machine is blameless. Run the sink and watch.
The ranking that matters
- A base tray filling from a small upstream leak — Top of the list here. Many machines catch upstream drips in a base tray; once the tray fills, it overflows all at once and the puddle looks like a burst. That much is common to the whole BWDB line.
- An overloaded drum forcing water past the seal — Second on this list. Overloading defeats a good seal. If the leak follows big loads and not small ones, this is why.
- A split or loose inlet hose — Third most likely. Hoses harden with age and split where they bend behind the cabinet. The washers inside the couplings flatten and weep at the tap. On the BWDB line this is the part that is reachable first.
- A blocked or overdosed detergent drawer — Fourth in the ranking. Detergent build-up in the housing is the commonest cause of water at the drawer face, and it is cured with a brush and hot water.
- A cracked sump or a failed pump housing — Fifth, and uncommon. Plastic housings crack where the hose clips pull on them, and a hairline crack leaks only under pressure.
The order to check in
- Pull the machine out and leave it out for a cycle — If the leak stops with the machine forward, a strained hose is the cause and the fix is clearance.
- Open and reseat the drain filter — Have a tray ready, unscrew it, clean the seal and its thread, refit it squarely and run a short cycle. The BWDB line puts this within reach without a teardown.
- Run a cycle with no load and a half dose — If the leak disappears with a small load and a small dose, the cause is overloading or over-dosing rather than a fault.
- Smell the water — A simple test that eliminates half the causes.
Isolate it first
Safety
Unplug the appliance or switch off its breaker, then close both taps. Work with the machine cold: a hot wash leaves the drum and the hoses hot enough to scald, and a filter opened straight after a cycle empties near-boiling water onto your hands.

Where the owner line is
The owner line is the cabinet. Everything reachable from outside it is yours; anything behind the front or top panel is a service call, and a tub seal in particular is a major job that is rarely worth guessing at.
