The SLTW answer in short
Water under an Avanti SLTW washer usually comes from a connection rather than from the machine itself. Inlet hoses, the drain hose, the filter cap and the door seal account for most leaks, and all four are reachable without opening the cabinet. Find the highest wet point first.
What this looks like in use
- Clean water at the back of the machine, even when it is off — On every SLTW model in the table, water with the machine idle is always the fill side — turn the taps off now.
- Water tracking along the floor from behind the machine — On an SLTW model, look for the source above the wet trail — water runs, so the highest damp point is nearest the fault.
- Soapy water at the front during the wash — For SLTW models, a door seal or a detergent dispenser overflowing, both of which show only under load.
- A slow weep from the bottom front hatch — Looking at SLTW models specifically, the filter cap is not sealing, usually because it is cross-threaded or its seal is damaged.
- Suds coming out of the dispenser or the door — Within the SLTW family, too much detergent, or the wrong kind for the machine, will foam out of any opening it can find.
- NEAR MISS — the machine will not start and the floor is dry — Then this is not a leak at all; the wont-start page for your model line covers it.
What goes wrong here, most frequent first
- An inlet hose or tap connection weeping — First, because it is under mains pressure all the time and because rubber washers harden and take a set.
- A drain hose connection loose or the hose split — Mid-list because it is easy to see once you know to watch during the drain step. That ranking holds across the SLTW line.
- A blocked dispenser overflowing — Caked powder narrows the channel and the incoming water then backs out at the front.
- A split sump, bellows or internal hose — Last: an internal leak means the cabinet has to come apart, and it is far rarer than the connections outside it. Nothing in the SLTW line changes that order.
What to look at first, second, third
- Turn the taps off and see whether the water stops — On SLTW models, it separates a supply leak from a wash leak in minutes and it protects the room while you think.
- Run a short cycle and watch each stage — Looking at SLTW models specifically, a leak that appears only at drain or spin is the pump side; one that appears during fill is the inlet side.
- Run a finger round the door seal channel — Debris in the fold holds the seal open under load, and it is the commonest front leak of all.
- Run one wash with a correct dose of the right detergent — Never use washing-up liquid or a hand-wash product in a machine.
Before you begin
Safety
Isolate the washer and close the supply taps before touching any fitting; a capacitor can stay charged after the power is off. Never chase a leak with the machine running and a panel off. A loaded machine is very heavy, so empty it before moving it and watch what its own hoses snag on.

Where the owner line falls
Owner territory is the taps, the visible connections, the seal, the dosing and the loading. Beyond that, call — and call the same day if water has reached a socket or the wiring, because that is an electrical hazard rather than a plumbing one.
