The short answer
A leaking Conservator NTW washer is usually leaking from a connection rather than from the tub, and when in the cycle the water appears tells you which connection. The brand-generic page establishes timing and position first; that is still the method here, and the family decides what to look at next. Two capacities on one platform is exactly the case where balance and load distribution move up the ranking: the larger tub tolerates an uneven load less well, and an uneven load is the cause most often mistaken for a mechanical fault.
What you observe
- Water at the back of the machine, present even when idle — A supply hose or its connection, which is under pressure at all times.
- Water at the front during the wash phase — The door seal on a front-loading machine, or the detergent dispenser overflowing back out.
- Water appearing only during the drain phase — The drain hose or its connection, which is pressurised only while the pump runs.
- Water below the filter access after a cycle — The filter cap not seated, which is the commonest leak after anyone has cleaned it.
- NEAR MISS — water inside the drum that will not leave — That is a drainage fault rather than a leak, and it has its own page.
Causes, most likely first on the NTW models
- Supply hose connections — First on this family. They are under mains pressure permanently, they are rarely inspected, and a rubber hose that has been in service a long time weeps at the collar before it ever bursts. This is also the only leak that continues while the machine is switched off.
- Pump filter cap not seated — Second, and almost always recent: a filter cleaned and not fully closed leaks a small amount at every drain phase and is easily mistaken for something serious.
- Air path length across the cabinet sizes — Ranked here because of the size spread in this table. A taller cabinet runs a longer air path with more cold surface for moisture to settle on, so it generates more frost for the drain to clear and reaches a visible leak sooner once the drain narrows.
- Door seal, boot or lid seal — Third. On a front-loading machine the boot collects debris in its lower fold, and anything held there stops the seal closing on itself. It leaks during wash, at the front, and often only on a full load.
- Detergent dispenser overflow — Fourth. A dispenser caked with detergent residue backs up and sends water out of the drawer front. It looks alarming and it is cleaned rather than repaired.
- Tub seal or a split hose inside the cabinet — Last. This is the one that needs the cabinet open, and it is worth reaching only when the four above are clean.
Check in this order, and why
- Establish which cabinet stem you own first — Ask what was in the drum before you touch the machine. On the larger stem a single heavy item explains more complaints than any component in the list below.
- Note when the water appears relative to the cycle — Idle points at supply, wash points at the door or dispenser, drain points at the drain side. This removes most of the list before anything is moved.
- Feel the supply hose collars at both ends with the machine idle — Dampness at a collar is the answer, and it is the only leak that does not need the machine running to find.
- Check the filter cap is fully seated and its seal is clean — Especially if the filter has been opened recently.
- Wipe out the lower fold of the door seal and inspect it — Debris caught there is a very common front-load leak and it is free to correct.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Close both supply taps before touching a hose connection, and be ready for the water the hose still holds. Water reaching an energised machine is the reason to isolate first and mop second. A loaded washer is extremely heavy: do not tip or drag it alone to look underneath, and do not run it with a panel off to watch a leak develop.

When to call a technician
Call when the hoses, the filter, the seal and the dispenser are all clean and water is still appearing, because the remaining causes are inside the cabinet. Call once load, levelling and the drain path are all clean, because the next step is under the tub and needs the machine moved. Replace a supply hose that is weeping rather than tightening it repeatedly: a hose that has begun to fail at the collar is the one component here that can flood a room.
