The short answer
On the Avanti FLW models covered here the leak candidates are few and mostly accessible: a heavy, tightly sealed drum behind a door boot, with a drain pump and filter behind the lower panel, a counterweighted suspension and a control that will not proceed until the door is locked. Most reports resolve to a hose connection, a seal that has collected debris, or a machine that is not standing level.
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.
- 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.
- Foam rather than water — Oversudsing.
- 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 FLW
- The door boot or the tub-to-cabinet seal — On a front-loader the boot holds water against the door on every cycle, and it collects the debris that eventually cuts it. Ranked first on Avanti FLW because everything on a front-loader sits downstream of the door boot and the pump filter, so that is where the diagnosis starts rather than where it ends.
- The pump filter cover — A filter cover that was not seated after cleaning leaks a small amount on every cycle, always from the same low corner.
- 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.
- Oversudsing — Foam escapes where water would not, so an apparent leak that only appears with a particular detergent is usually the detergent.
- 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. 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.
- Inspect the door seal or the tub-to-cabinet seal — Run a finger right round the bottom of it and look for grit, a hair clip or a tear. The bottom of the seal is where everything collects.
- 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, and the door lock stays engaged for a period after a cycle ends — wait it out rather than forcing the door. 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 FLW the accessible causes above cover most reports and cost nothing but a cycle and a torch. A note on scope: this page is written for the FLW compact front-load washer and for the one model number the variant table names. A sibling family from the same brand will have a different order.
