The short answer
A leaking Bangson portable washer is usually leaking at the tap adapter or the drain hose, not at the tub: both are connected by hand before every wash and neither is a permanent fitting. Find out whether the water appears during fill, during drain, or throughout, because that single observation names the joint for you.
What you observe
- Water at the tap while the machine fills — The adapter or the hose washer is not sealing.
- Water at the sink or behind the machine during drain — The drain hose has slipped or is splashing out of its outlet.
- A slow puddle under the cabinet at any time — A tub, hose or pump-housing leak inside the machine.
- NEAR MISS — the machine overflows the tub — That is a fill or level fault, not a leak, and it belongs with the cycle-fault page.
Causes, most likely first on this brand
- The tap adapter or fill-hose washer — First on this platform because it is made and unmade constantly. A missing or hardened rubber washer, or an adapter that is cross-threaded onto a tap it does not quite fit, weeps under pressure the whole time the tap is open.
- The drain hose jumping its outlet — Second, and it is not really a machine fault: the hose is stiff, the pump gives it a push at the start of the drain, and an unsecured hose flips out of the sink. The water then goes wherever the floor slopes.
- A split or perished hose — Third. Portable machines are moved, stored and coiled, and hoses crack where they are bent tightly. The leak appears only while that section is pressurised, so it comes and goes.
- The tub, pump housing or internal hose clamp — Last, because it is the only cause that needs the cabinet open, and on a light plastic tub it is often the result of months of walking and vibration rather than a sudden failure.
Check in this order, and why
- Note when the water appears: fill, drain or all the time — It splits the ranking into thirds before you touch anything.
- Dry everything and run a fill with the machine pulled out — Watching a dry machine fill names the joint in a minute.
- Check the drain hose is secured at its outlet — A tie or hook stops the most common floor-water case outright.
- Only then look under the cabinet for an internal leak — That is where the owner check ends and a stripdown begins.
What an owner can safely check
- Check and replace the fill-hose washer — A flat, hard or missing washer is the commonest leak of all, and the part costs very little.
Tools: pliers, new washerAbout 15 min
- Re-fit the tap adapter squarely — Hand-tighten onto clean threads; force on a mismatched tap will not seal.
About 10 min
- Secure the drain hose at its outlet — Tie or clip it so the pump's first surge cannot flip it out.
Tools: cable tieAbout 10 min
- Inspect both hoses along their length — Flex them gently and look for cracks at the tight bends.
Tools: torchAbout 15 min
- STOP HERE if water comes from under the cabinet — Tub and pump-housing leaks mean opening the machine.
Before you open anything
Safety
Unplug the washer before investigating any leak, and close the tap: water and a powered appliance on the same floor is the hazard here, not the repair. A capacitor can hold a charge after the power is off, so wait before opening any panel. Never leave a portable washer connected to a tap and unattended, because a hose that lets go while the tap is open does not stop.
When to call a technician
Call when both hoses and the adapter are sound, the drain hose is secured, and water still appears under the cabinet. That points at the tub, the pump housing or an internal clamp, which means a stripdown. Call immediately if water is reaching the mains outlet or the lead, and switch that circuit off before you deal with anything else.

This page is written for Bangson portable washers as a class rather than for one model. Deliberately absent here: hose thread sizes, adapter part identifiers, tub capacities and clamp specifications, which differ by family and belong on the family or model page.
