The short answer
Water around a SPS machine usually comes from the door, from a connection or from foam, and only rarely from the tub itself. The table below carries a single model code for this family, so everything on this page describes one build: the panel layout and the part positions do not shift under you.
What you observe on these models
- Water at the door sill, on the floor in front of the machine — The seal, the door alignment, or suds. Look for foam at the sill: foam means detergent, not a part.
- Foam or suds visible at the bottom of the door — Hand dish soap, or far too much detergent, or a rinse-aid spill.
- Water appearing under the toe-kick only during a cycle — Something under the tub is wet while pressurised: a hose clamp, the pump seal, or the sump gasket.
- NEAR MISS — water standing inside the tub, floor dry — That is drainage, and it has its own page for this family.
Causes, most likely first on the SPS family
- Over-sudsing from the wrong detergent — First on the list, and the most common cause in a household that is new to the machine.
- The door seal is hardened, torn or out of its channel — Second. Run a finger round the whole seal: a section standing proud of its channel, a tear at a corner, or a flat spot where the door has sat closed for years all leak in the same place.
- The door is out of alignment or the latch is not pulling it in — It ranks here on a narrow family because misalignment is usually introduced at installation — an out-of-square cabinet opening, or a panel fitted without resetting the hinge tension.
- The drain hose connection or the air gap is overflowing — Worth checking early despite its rank, because it is entirely outside the machine and the water it produces looks exactly like a tub leak once it reaches the floor.
- The tub seam or a spray arm feed has split — Last, and genuinely rare on units of this age. Reach it by elimination, never by assumption.
Check in this order, and why
- Dry the floor completely and put paper down — A sheet of kitchen paper across the sill and another under the toe-kick turns an invisible weep into a dated map.
- Look for foam before you look for a part — Foam at the sill means detergent. Run one rinse-only cycle with nothing in the cup and confirm the floor stays dry before you buy anything.
- Work round the door seal with a finger and a light — Feel for hard sections, tears at the corners and any length that has lifted out of its channel.
- Run a short cycle and watch the first ten minutes — Stay with it. A leak that starts at fill is the supply side; one that starts at the wash is the door or the sump; one that starts at the drain is the hose connection.
- Only then look under the toe-kick — Power off, panel off, torch in. A wet clamp, a wet sump seam or a stained pump body names the part — and names a job that needs the machine unseated.
Models in the SPS family — One code stands for this family, so the table is a single line and there is nothing to cross-check beyond it.

Before you open anything
Safety
Water and electricity are in the same place in this fault, so switch the breaker off before you mop under the machine or take the toe-kick off; a capacitor can hold a charge after the power is off. Shut the supply valve under the sink before touching any fitting.
When to call a technician
Detergent, the door seal, the door alignment and the fittings under the sink are yours on these models. Anything that only shows itself as a wet toe-kick during a cycle is not: that is the sump, the heater seal or the pump seal, and the machine has to come out of the cabinet. Call sooner if water is reaching a cabinet base or a wooden floor.
