Expert troubleshooting guides for leaking coffee maker problems.
Water in the drip tray on a BES880 is the thermocoil purge, not a leak. Water under it is one of three things Breville names in the manual.
Water on the counter instead of in your mug? Five K-Mini leak fixes sorted by where the puddle appears — most are a clogged exit needle or a fill spill.
The Essenza Mini manual's leak row: position the capsule correctly. Then empty the drip tray, drip base and 5-6 capsule container every day, as it asks.
This entry-level model's simpler tank valve and hose O-rings tend to wear sooner than the equivalent parts on pricier DeLonghi machines.
Precision Brewer leaking? Breville's book traces it to the basket drip-stop seal, basket overflows, an overfilled carafe, the carafe drip stop or the showerhead.
Nespresso lists one Inissia leak: around the capsule area, fixed by placing the capsule correctly. Check the drip tray and tank next, then contact Nespresso.
Work out which container is wet first. Under the machine, in the capsule bucket and around the tank are three different faults with three different fixes.
Water on the counter after cold brews? The K-Brew+Chill's automatic rinse, 7oz drip tray, Chill Tank and pod holder explain most leaks. Here's how to tell which.
A Stilosa leak is usually a tank not pressed down, an overdosed or loose filter holder, a full drip tray or an open steam knob. Fixes from its own manual.
Coffee round the portafilter, a dripping hot water outlet or steam from the group head: each Oracle leak has its own row in Breville's books, and its own fix.
The Vertuo Up manual says a few ml in the drip tray per brew is normal. Empty it with the capsules, then check the tank, module and for a stuck capsule.
The Duo's dual hot-and-iced milk system is new territory for the Magnifica line, and it's often the real source of a "leak" that looks like it's coming from the base.
Tank latch, drip-tray float, milk jug on its sensor, and the shower-screen seal. The BES881 book's owner fixes for water where it shouldn't be.
Lattissima leaks come from the capsule area, the milk system or the trays. Rinse the milk system after each drink and clean it after each use.
The K-Iced Essentials guide points to reused pods, an unseated reservoir and the drip tray. Fixes, plus Brew Over Ice and descaling from the guide.
The Evo manual names the cause of water on the counter: the drip tray grille wasn't refitted. Then the drip tray, condensate tray and rinse water.
Water under or around a Nespresso Pixie? Five checks from the EN125 and BEC430 manuals, from the tank position to the capsule, before calling Nespresso.
The K-Cafe uses a simpler single-needle system than newer Keurigs, which means fewer places a leak can actually come from — here is how to narrow it down fast.
Water pooling under the reservoir, dripping from the pod holder, or leaking out the base? Each location points to a different seal — here is how to identify which one and fix it without replacing the machine.
A few drops during warm-up is normal ThermoJet purging, not a leak — here's how to tell that apart from the real leak points on this model.
Water in the drip tray, under the tank or around the portafilter? Where each leak comes from on the BES840, and how to replace the one owner part, the seal.
The BES500 book names two leak causes: auto purge into the drip tray after steaming, and an unlocked tank. Fixes for both, plus cleaning and descaling.
Water under your K-Duo Plus, or dripping from the carafe spout when you pour? These are two different problems with two different fixes — here's how to tell which one you have.
Water in the capsule container, on the counter or under the machine? Each points to a different CitiZ fix, and the manual names exactly one leak.
Water under the drip tray, behind the tank or around the portafilter? Breville's BES870 book names three causes, and one of them is by design.
Most Dinamica puddles are the drip tray: the switch-on rinse fills it and the red indicator warns before it overflows. What's normal, and when it's a real leak.
The K-Elite guide has no leak row. Its care pages point to the 8 oz drip tray, the reservoir seating, the pod holder and storing it upright.
Most water under a Magnifica S is an overflowed drip tray. Empty it before the red indicator rises, then check the condensate tray, inside and infuser.
Usually it's overfilled: froth up to MAX FOAM (120 ml) and hot milk up to MAX MILK (240 ml) on the Aeroccino 4. Then the lid seal and a dry base.
Water pooling under your K-Slim after every brew? These 5 fixes stop the leak -- most take under 10 minutes and cost nothing to try.
Switched to the reusable filter and now you're getting puddles or watery coffee? These 5 fixes cover the two most common My K-Cup complaints at once.

Leaking lid, cracked carafe or a lid that won't stay on? Cuisinart sells lids and carafes by model through Customer Service. Check, order and test one.
Gaggia Classic Pro leaking? Drain pipe water and drips after removing the portafilter are normal. Real leaks: too little coffee, holder not locked, dirty seal or rim.

Nespresso's own answer to a leaking Vertuo Pop is two lines: seat the water tank, then descale. Here's that, plus the two leaks that aren't faults.
Philips leaking? Philips says rinse water drains into the drip tray by design. Real causes: tray overflow, tank not pushed in, dirty brew group, a slope.

Krups coffee maker dripping or leaking water? These 5 fixes stop leaks for EA8108, XP6020 and Dolce Gusto models, from Krups' own manuals.
Vertuo Next leaking? Nespresso's fix: check the water tank is well positioned, then descale. Water in the head after cleaning is normal: dry it.
BUNN names three causes when the funnel overflows: the wrong filters, a missing sprayhead, and slow-draining coffee. Here's how to fix each one.
Cuisinart's booklets name the causes: too-fine coffee, two filters, a non-Cuisinart gold-tone, too much coffee and a carafe left out more than 20 seconds.
Water under your Rivelia? Usually an overflowing drip tray or brew group seal, both quick to fix. 5 fixes for every ECAM450 leak source.
