The short answer
On a machine of this age the door seal is the leading cause: clean it, then press it and see whether it springs back. Perished hoses and hardened clamps are second, and they leak with the machine idle. Excess foam is third and free to rule out. A tub or pump seal is last and usually decides whether the machine is worth keeping.
What you observe
- A damp patch that has become a puddle over months — A seal hardening gradually.
- The seal stays dented when you press it — It has stopped recovering and will not hold.
- Damp behind the machine with it switched off — A perished hose or a tired clamp.
- Suds visible through the door during a cycle — Wrong detergent, or far too much of it.
- NEAR MISS — a puddle after opening a hot machine — Condensation, not a leak.
Causes, most likely first on this brand
- Door seal hardened past recovery — First because it is the part that ages fastest on this platform, and every machine wearing this badge is old enough. A seal that no longer springs back seals only where the door presses hardest.
- Perished hoses or tired clamps — Second, and distinguished by timing: these weep with the machine switched off, because the inlet side is held at pressure whenever the tap is open.
- Excess foam from the wrong detergent — Third, and free to rule out with one correct-dose cycle. Foam climbs the tub and rides over even a healthy seal, which sends people after the wrong part.
- Tub or pump seal failed — Last. This is the one that decides the machine's future, because on a dishwasher of this vintage the repair frequently costs more than a replacement.
Check in this order, and why
- Press the door seal all the way round — Free, and it names the top cause immediately.
- Clean the seal and the lip it closes on, then retest — Residue holds a seal off as well as wear does.
- Look behind the machine with it switched off — Damp here is the hoses, not the door.
- Run one cycle with the correct detergent dose — Left until here because it is quick to prove.
What an owner can safely check
- Switch off, pull the machine out and dry everything — Include the plinth and the neighbouring cabinet bases.
Tools: towelAbout 45 min
- Clean the door seal and press it all the way round — It should spring back everywhere, not only in places.
Tools: clothAbout 20 min
- Inspect the hoses and clamps for damp and crusting — Look with the tap open and the machine switched off.
Tools: torchAbout 20 min
- Run a cycle with a correct dose and no additive — If the leak stops, foam was the whole story.
About 60 min
- STOP HERE if water comes from the base of the tub — Tub and pump seals mean stripping the machine.
Before you open anything
Safety
Unplug the machine or switch off its breaker before moving it or opening any panel; a capacitor can hold a charge after the power is off, and water under a fitted kitchen can reach cables you cannot see. Turn the supply tap off before disturbing a hose, and replace a perished hose rather than tightening it. Never defeat an anti-flood device to get a cycle to run.
When to call a technician
Call when the seal is clean and springy, the hoses are dry, the detergent is right and water still appears — the tub or pump seal is then the answer. At this age ask for the price against a replacement before agreeing to the work. Check the cabinet bases either side for swelling and mention it, since the joinery damage often outruns the repair.

What this page does not cover
This page is written for the brand and the appliance class, not for one family or model line. Where a family- or model-specific page exists for your unit, that page is the more specific answer and you should start there. Deliberately absent: seal and hose part identifiers, clamp sizes, base tray dimensions and fault-code meanings, all of which differ between the integrated, freestanding and slimline families.
