The short answer
Water at a portable washer comes down to one thing more often than any other: the sink the machine drains into is backing up. Next on the list: an inlet hose connection is weeping. When the water appears — at fill, during the wash, at drain, or with the machine idle — narrows this faster than any tool will.
What you observe
- Water on the floor around the machine — When it appears matters more than how much there is.
- Water is around the sink rather than around the machine — That is the plumbing, not the appliance.
- A slow puddle behind the machine that returns after mopping — Only mains-pressure water refills while nothing is running.
- The water is foamy rather than clear — Foam on the floor is a dosing answer, not a plumbing one.
- NEAR MISS — the water is foamy rather than clear — That is a detergent dose, not a plumbing fault.
Causes, most likely first on this machine
- The sink the machine drains into is backing up — First on a portable machine: a sink hookup rather than a plumbed standpipe means the water on the floor is often the sink's, not the machine's. A part-blocked trap cannot take a pump's output in the time the pump takes to deliver it, and the overflow is at the sink rather than at the appliance.
- An inlet hose connection is weeping — Ranked here because it is the only water on the machine that is pressurised continuously.
- Too much detergent is making suds that climb out — Ranked here because it is free to test and it explains a leak that comes and goes with the wash load.
- The tub-to-pump hose or its clamp has let go — Last, and a service job — it is behind the front panel with the machine on its side.
Check in this order, and why
- Watch the sink while the machine drains — The overflow point tells you whose water it is.
- Dry behind the machine and check with the machine idle — Pressurised water returns with the machine switched off.
- Run a wash with a much smaller detergent dose — A machine that stops leaking on a small dose was never faulty.
- Note how fast and how much water arrives — A sudden large volume from the middle is the sump hose.
What an owner can safely check
- Dry the floor and run a short cycle, watching — Note the exact stage the water appears at; that is the diagnosis.
Tools: towelsAbout 45 min
- Clear the sink trap and retest a drain cycle — Run the tap hard first and see whether it clears.
Tools: bucketAbout 25 min
- Dry behind the machine and recheck after a few hours idle — If it returns, shut the taps and call.
Tools: towels, torchAbout 20 min
- Run one cycle at a fraction of your usual dose and watch — Use the machine’s own measure, not the detergent maker’s.
About 60 min
- STOP HERE before removing a panel or a hose clamp — Mains-pressure water behind a cabinet full of electrics is not owner work.
Before you open anything
Safety
Unplug the machine or switch off its breaker before removing any panel, and turn off the supply taps before touching a hose. A capacitor can hold a charge after the power is off. Disconnect the faucet adapter before moving the machine, and never run it unattended on a hookup — a hose that jumps the sink rim empties a full drum onto the floor.
When to call a technician
Call once the bellows, the drawer and the dose are all ruled out and water is still arriving, or as soon as the water is behind the machine and refilling after you mop it. Mains-pressure water does not stop on its own. Call immediately if water is reaching the outlet or running under an adjoining appliance.

What this page does not cover
This page is written for the brand and the machine class, not for one family or model line. Where a family- or model-specific page exists for your machine, that page is the more specific answer. Deliberately absent: hose and adapter part identifiers, lift heights and capacity figures, which differ between the single-tub and twin-tub families.
