The short answer
The single most useful thing you can establish about a leak on Avanti CTW is which part of the cycle it happens in: fill, wash or drain. Each stage pressurises a different part of the machine, so the timing narrows the cause before anything is moved. On a compact top-loader the cabinet is lighter than the load it spins, so anything that upsets the balance moves the whole machine.
What you observe on these models
- Water only while it is filling — Fill-stage leaks are on the supply side, which is the most accessible part of the machine and the easiest to fix.
- Water only during the drain step — A drain-side leak: the connection at the standpipe, or a standpipe that overflows because it cannot take the flow.
- Water at the front of the machine under the door — On a front-loading machine this is the boot; on a top-loader it is more likely to have travelled from elsewhere.
- A small amount from the same low corner every cycle — Repeatable position and small volume points at a filter cover or a seal rather than a burst.
- NEAR MISS — water under the machine after it has been idle for days — That is a supply connection dripping with the machine off, and the tap should be closed until it is fixed.
Causes, most likely first on CTW
- The fill hoses and their washers — Hose connections are the most common washer leak and the easiest to confirm: they are accessible, they drip under pressure, and the water is clean. Ranked first on Avanti CTW because these models are frequently plumbed temporarily rather than permanently, which makes the hoses and the standing surface the first variables rather than the last.
- The drain connection or an overflowing standpipe — Water appearing only during the drain step is a drain-side report, not a tub-side one, and the timing separates them cleanly.
- The machine is not level — A machine that walks during spin can unseat a hose or move against a wall, and the leak is then a consequence rather than a cause.
- Overfilling — A machine that fills past its normal level pushes water out wherever the tub is not sealed against pressure, which is rarely where the fault is.
- Oversudsing — Foam escapes where water would not, so an apparent leak that only appears with a particular detergent is usually the detergent. Last on this list, and the item that every cause above it can imitate exactly.
Check in this order, and why that order
- Dry everything and place paper at each corner — Run one cycle and read the paper. Position plus stage is most of the diagnosis and it costs one cycle.
- Check both fill hose connections by hand — At the tap and at the machine, with the taps open. A weeping connection is usually a washer or a cross-thread rather than a hose.
- Re-seat the pump filter cover — A cover that was not tightened after cleaning leaks a little on every cycle, which is exactly the pattern people find hardest to trace.
- Put a level on the top of the machine — A machine that walks unseats hoses and moves against walls, so levelling is both a fix and a prevention.
Before you open anything
Safety
Unplug the washer or switch off its breaker before removing any panel, and close the tap before touching a fill hose. A capacitor can hold a charge after the power is off. Close both taps before working on any hose connection, and mop the floor before moving the machine.

When to call a technician
Call when the leak is not at a hose, not at a seal you can see, and not at the filter cover — at that point it is inside the cabinet and the machine has to come apart. Call immediately if water is reaching an outlet, if the machine has tripped protection since the leak began, or if the leak is large enough to appear during a single cycle. On Avanti CTW the accessible causes above cover most reports and cost nothing but a cycle and a torch. Check the plate before acting on any of this. CTW is a compact top-load washer, and the ranking above is written for that construction rather than for the brand as a whole.
