The short answer
Water around a Ostba washer is usually the faucet adapter or quick connector at the tap. Where the water shows up is the single most useful clue you have, because it splits the list below in half. This is a compact automatic machine with programmes of its own, hose-fed and hose-drained rather than plumbed in, and that is what sets the order below. These are fitted under a counter in an office or a small kitchen, which means a cutout, a fixed position and very little airflow at the back.
What you observe
- Water near the tap or the sink rather than under the machine — Where the water appears is the single most useful clue.
- Water on the floor only during the spin — Timing separates a pressure-dependent leak from everything else.
- Foam escaping from the top of the machine — Almost always detergent quantity rather than a fault.
- NEAR MISS — water only after an overfill during a power cut — That is a one-off and it does not recur once the machine is running normally.
Causes, most likely first on this platform
- The faucet adapter or quick connector at the tap — First on a portable by a long way: that connector is fitted and removed constantly, its washer hardens, and it weeps under pressure while the machine runs. The water appears near the sink rather than near the machine, which is why it gets blamed on the wrong thing. Anything that depends on air behind the cabinet is therefore compromised before the appliance has done anything wrong.
- Too much detergent, with foam finding its way out — A small drum needs far less detergent than a full-size machine, and foam rises and escapes wherever it can. It is the most common cause of a leak that appears only on certain loads.
- The drain hose jumping out of the sink — Ranked second because it happens during spin, when nobody is watching, and it puts a great deal of water on the floor in seconds. A hose that is merely hooked over a lip is not secured.
Check in this order, and why
- First: dry the tap connector and watch it through a fill — It tests the most common cause on this platform, and the water shows at the sink rather than at the machine. On a unit fixed into a cutout, start with what the cutout is doing to the air behind it.
- Second: run one load with a fraction of the detergent — Cheap, quick, and it resolves the leaks that only happen on certain loads.
- Third: secure the drain hose and watch a full spin — A hose merely hooked over a lip is not secured, and it leaves during spin when nobody is looking.
What an owner can safely check
- Dry the tap connector and watch it through a fill — The faucet adapter is the commonest leak on this platform and its water shows up at the sink.

- STOP HERE before opening the cabinet — Unplug it first, and then hand it over — tub seals are not an owner repair on a machine this size.
Before you open anything
Safety
Unplug the machine before you open any cover — mains wiring and standing water share the inside of this cabinet. Bail the tub out before you tip or move it, both because the water will go over the floor and because a full machine is far heavier than it looks. Never run it with a cover off to watch what happens, and keep the drain hose secured before every spin rather than after the first flood.
When to call a technician
Call when the tap connector and the drain hose are both dry and secure, the detergent quantity has been halved and water still appears during the spin. Call immediately, before wiping anything, if water is reaching a socket or a power lead — switch it off at the breaker first if you can do so safely.

What this page does not cover
This page is written for the appliance class and this symptom, not for one family or model line. Where a family- or model-specific page exists for your unit, it is the more specific answer and it is linked from the sibling list — go there first if your model is named there. Deliberately not here: wiring colours, board part numbers, torque figures and panel-removal sequences, all of which differ by family.
