The short answer
Start with a hose connection that has worked loose: on a Cixi Hengma portable impeller washer it accounts for more of these than anything else, and the tap adapter rather than the machine is the next thing to rule out. This is a single-tub portable driven by an impeller plate in the base rather than an agitator post, so it washes by moving water rather than by dragging the load through it. Two of the four are owner work; the last one on the list is not, and knowing which is which saves the call-out.
What you observe
- Water on the floor during the fill — Fill-time water points at the supply connections rather than at the machine.
- A drip at the tap while the machine is idle — The connection is leaking under standing pressure, which is a different and more serious thing.
- NEAR MISS - the floor is damp only in humid weather — Condensation under a cold machine is not a leak, and no repair will change it.
Causes, most likely first on this brand
- A hose connection that has worked loose — The likeliest cause on this brand: every connection on this machine is made and unmade by hand, often by different people, and a fitting that is finger-tight rather than properly seated weeps steadily under pressure.
- The sink adapter or the tap connection — Next most likely: a portable connects to a tap through an adapter that was never designed to hold pressure all day, and the leak usually starts the moment somebody turns the tap on and walks away.
- Too much detergent — Third on the list: excess suds climb out of the tub and through vents that water would never reach, and the puddle they leave looks exactly like a failed seal.
Check in this order, and why
- Check every hose fitting for a missing or perished washer — Free, quick, and it is the classic cause of a slow weep.
- Watch the tap and the adapter during the fill — On a portable this is the likeliest source and the only one that can keep running after the cycle ends.
- Run a rinse with no detergent and watch — Half an hour, no tools, and it removes the commonest false leak.
What an owner can safely check
- Hand-tighten every hose connection and check each washer is present — A missing rubber washer is a classic, and it is invisible until the fitting comes apart.
Tools: clothAbout 15 min
- Reseat the tap adapter and turn the tap off between washes — On a portable this is the fix and the prevention in one step.
About 10 min
- Run a rinse cycle with no detergent at all — If the foam and the water stop, the dose was the fault.
About 30 min
- STOP HERE if finding the leak means opening the cabinet — Mains voltage sits beside standing water inside this machine - that is where owner checks end.
Before you open anything
Safety
Unplug the machine before opening any panel, before reaching into a pump filter and before tipping it to look underneath. This is an appliance that puts mains voltage within inches of standing water, and a capacitor can hold a charge after the power is off. Never defeat the lid or door interlock with tape, a magnet or a screwdriver: it exists to stop a tub turning while your hands are in it.
When to call a technician
Call when the fittings are sound with their washers, the tap is off between washes, the dose is right and water still appears. Anything that means opening the cabinet to trace is a service call on this machine, because the motor and control sit directly under a tub full of water.
