Breville Barista Touch Leaking Water? 5 Fixes (BES880)

Most Barista Touch "Leaks" Are the Machine Doing Its Job

Water in the drip tray on a Breville Barista Touch (BES880) is usually not a leak. Breville's instruction book lists an auto purge under the heading "Water leaking": immediately after the espresso, hot water and steam functions, the machine pushes water into the tray to hold the thermocoil at the right temperature. You meet that water at the start of your next session, which is why it looks like an overnight leak.

The question worth answering first is therefore not why is it leaking but where is the water. Water in the tray is normal and expected. Water under the tray, on the counter, or running down the front of the machine is not, and Breville documents three causes for it: a tray that has not been pushed fully home, a water tank that is not locked down, and a shower-screen silicone seal that has aged out.

This guide covers the BES880, the manual-tamp Barista Touch. The Barista Touch Impress (BES881) adds the Impress puck system and has its own leak guide.

Try This First

• Look in the tray before you look under it. If the EMPTY ME! indicator is floating up through the grill, the tray is simply full. Empty it and watch again for a day.
• Push the drip tray firmly home. Breville's own remedy for auto-purge water ending up where you do not want it is exactly this, plus emptying the tray whenever EMPTY ME! shows.
• Press the water tank straight down until it locks. A tank that is not "fully inserted and locked into position" appears as a cause under leaking, under no water at the group head, and under pulsing pump noise.
• Note when the water appears. Right after a shot or a steam cycle points at the purge. Only on power-up points at leftover purge water from last night. Continuous dripping while idle points at Fix 4.
• Check the portafilter rim. Grounds on the rim break the seal at the group head, and espresso then runs around the edge instead of through the spouts.

Where the Water Is Coming From

Fix 1: Confirm the Auto Purge and Empty the Tray Properly (Works About 35% of the Time)

The thermocoil is a single heating circuit doing espresso, hot water and steam, and the purge is how the machine drops it back to extraction temperature between jobs. Breville names the behaviour and gives the remedy in one line: keep the drip tray firmly in place and empty it whenever the EMPTY ME! indicator shows.

Signs it's this one:

• The water is clear, not coffee-coloured
• It appears immediately after steaming or a Long Black
• The volume is small and consistent, not a puddle that grows while the machine sits idle

Steps:

1. Remove the drip tray by sliding it out level, taking care if it is full.
2. Lift out the grill and the removable wet and dry coffee separator, and tip the grounds away.
3. Pull the EMPTY ME! indicator upwards to release its side latches so you can clean under it.
4. Wash all the parts in warm soapy water with a soft cloth, rinse and dry thoroughly.
5. Reassemble and push the tray firmly back in until it sits square against the machine.
6. Brew one shot and steam one jug, then check the tray. A small amount of clear water is the purge working as designed.

Time: 10 minutes
Cost: Free
Success Rate: About 35%
Difficulty: Easy

Worth knowing: the milk jug rests on a temperature sensor built into the drip tray, so a tray sitting crooked or a sensor buried under standing water and grounds can also upset automatic milk texturing. Cleaning the tray properly fixes more than the puddle.

Fix 2: Empty the Tray Before Descaling, Not After (Works About 10% of the Time)

A descale cycle pushes a large volume through the machine in a short time, and Breville prints a specific safety instruction about it: before descaling, make sure the drip tray is empty and inserted, and take care because hot steam may be released. A descale started with a half-full tray is one of the easiest ways to end up with hot, acidic water on the counter.

Signs it's this one:

• The flood happened during or just after a descale or cleaning cycle
• The machine had prompted you to descale and you started straight away

Steps:

1. Empty and refit the drip tray before you begin.
2. Go to Settings and select Descale cycle, then follow the screen.
3. Keep the tray within reach and empty it whenever the cycle pauses and EMPTY ME! appears.
4. Remember that the cleaning cycle is a separate thing. It back-flushes the group head and cleans the shower screen, and the machine prompts for it independently of descaling.

⚠️ Safety: hot steam can be released during descaling. Keep hands and face clear of the group head and steam wand while the cycle runs, and do not lift the tray out while water is flowing.

Time: As long as the cycle takes
Cost: Cost of descaling solution
Success Rate: About 10%
Difficulty: Easy

Fix 3: Seat the Water Tank Until It Locks (Works About 20% of the Time)

The 2 L tank slides in at the back and has to be pressed down completely to engage. Breville lists "water tank is not fully inserted and locked into position" under leaking, under no water flow, and under pulsing pump noise, which tells you how often it is the answer. A tank that is not seated can weep at the connection and starve the pump at the same time.

Signs it's this one:

• Water appears at the back or underneath rather than in the tray
• The pump pulses or surges during extraction
• You had the tank out recently to refill or to change the filter

Steps:

1. Lift the tank out and dry the area behind it so you can see fresh water arriving.
2. Check the filter holder is properly attached and the filter is seated in it.
3. Fill the tank with cold water before sliding it back into position at the back of the machine.
4. Press it straight down until it locks into place.
5. Run a Long Black or the hot water outlet, then look behind the machine with a torch.

Time: 5 minutes
Cost: Free
Success Rate: About 20%
Difficulty: Easy

On water: Breville rules out highly filtered, demineralised and distilled water for this machine, and says never to use water with no or low mineral content. If your tested hardness comes back at 4 or 5, Breville recommends changing to a different water source rather than relying on the built-in filter. Replacing that filter every 3 months or 40 L is what keeps descaling intervals long.

Fix 4: Stop Espresso Escaping Around the Portafilter (Works About 20% of the Time)

If the water arriving on the bench is brown, it is coming out of the group head rather than out of a tube. Breville's troubleshooting for espresso running around the edge of the portafilter gives four causes, and three of them are dose and seal problems you can fix in a minute.

Signs it's this one:

• The escaping water is coffee-coloured
• It happens during extraction and stops when the shot stops
• The portafilter is hard to rotate into place, or feels loose

Steps:

1. Wipe excess coffee from the rim of the filter basket so the basket can seal in the group head. This is the single most common cause.
2. Lower the dose if the basket is over-full, and after tamping use the Razor dose trimming tool to trim the puck level.
3. Tamp at around 10-15 kg of pressure, the figure Breville repeats throughout the troubleshooting table.
4. Insert the portafilter completely and rotate it until you feel resistance.
5. Wipe the group head interior and shower screen with a damp cloth to clear ground coffee particles.
6. Purge the machine: put an empty filter basket and portafilter in the group head, touch the Hot Water button and run a short flow to rinse out residual coffee.

Time: 5-10 minutes
Cost: Free
Success Rate: About 20%
Difficulty: Easy

If the leak survives all of that, the seal itself is the suspect. That is Fix 5.

Fix 5: Replace the Shower Screen Silicone Seal (Works About 15% of the Time)

Breville treats this as a wear part, not a repair: "Over time, the silicone seal surrounding the shower screen will need to be replaced to ensure optimum brewing performance." It appears as a cause under both "water leaking" and "espresso runs out around the edge of the portafilter", because a hardened seal stops the portafilter locking in tight enough to hold pressure.

Signs it's this one:

• The portafilter has started going in further than it used to
• Coffee escapes around the edge even with a clean rim and a correct dose
• The machine has years of daily use behind it

⚠️ Safety: power the machine off at the POWER button and unplug it before you start, and let it cool. The group head and shower screen sit directly under a hot thermocoil.

Steps:

1. Press the POWER button to switch the machine off and unplug the cord from the outlet.
2. Carefully remove the water tank and drip tray, taking particular care if they are full.
3. Using a skewer or similar, clean the centre of the shower screen screw of any residual coffee.
4. Insert a flat-head screwdriver into the centre of the screw and turn counter-clockwise to loosen it.
5. Remove and keep the screw and the stainless steel shower screen. Note which side of the screen faced downwards, which makes reassembly easier. Wash the screen in warm soapy water and dry it thoroughly.
6. Remove the silicone seal with your fingers or long-nose pliers. Insert the new seal flat side first, so the ribbed side faces you.
7. Refit the shower screen, then the screw. Turn the screw clockwise by hand for two or three revolutions before using the screwdriver, and tighten only until the screw is flush with the screen. Do not overtighten it.
8. Refit the drip tray and water tank, plug in, and pull a shot to test.

Time: 20-30 minutes
Cost: Price of a replacement silicone seal from Breville
Tools: Flat-head screwdriver, skewer, long-nose pliers
Success Rate: About 15%
Difficulty: Moderate

Breville's instruction book points owners to Breville Consumer Support or the Breville website for replacement seals or advice, which is also the right route if the screw will not release.

Is It Fixed?

Dry the counter and the area behind the machine completely, then run one espresso, one steam cycle and one hot water pour. Wait ten minutes without touching the machine. Clear water in the tray is the purge. A dry counter and a dry tank recess mean the job is done. Brown water anywhere means go back to Fix 4.

When DIY Won't Work

Stop using the machine and unplug it if you see:

• Water pooling under the base or reaching the power cord
• A burning smell, sparks, or the machine tripping a breaker
• Steam escaping from anywhere other than the wand
• A crack in the water tank or in the group head housing

One more Breville-documented stop sign: if the machine is on but ceases to operate, the safety thermal cut-out may have activated because the pump or the grinder overheated. Breville's instruction is to press POWER to switch off, unplug from the outlet, and allow 30-60 minutes to cool. If it happens again after that, call Breville Support rather than repeating the cycle.

Warranty. The documented owner-serviceable parts on this machine are the drip tray, the shower screen and its silicone seal, the water filter and the steam wand tip. Going further into the housing is not covered by the instruction book, and on a machine at this price it is worth a support call first. Breville's own book sends owners to Breville Consumer Support for seals and advice.

Prevention

• Empty the drip tray on a schedule, not when EMPTY ME! appears. The purge fills it faster than most owners expect.
• Wipe the basket rim before every lock-in. It takes two seconds and prevents the most common escape route.
• Wipe the steam wand with a damp cloth before lowering it, so the automatic purge can clear the milk properly.
• Replace the water filter every 3 months or 40 L. Breville ties that interval directly to how often you will need to descale.
• Run the periodic purge: empty basket and portafilter in the group head, touch Hot Water, short flow.
• Descale when the machine asks, with an empty tray in place, and run the cleaning cycle when prompted — they are two different jobs.
• Use suitable water. No distilled, demineralised or heavily filtered water, and change water source altogether if your hardness tests at 4 or 5.

FAQ

Is water in the drip tray after every shot normal on a Barista Touch?

Yes. Breville lists the auto purge as a cause of apparent leaking and describes it as normal operation: immediately after the espresso, hot water and steam functions the machine purges water into the drip tray to keep the thermocoil at the optimal temperature. The remedy given is to keep the tray firmly in place and empty it regularly, not to seek a repair.

Why does it only seem to leak when I first turn the machine on?

Because the purge runs at the end of a session, not the start. The water you find on power-up was put there when you finished the last drink. Empty the tray after your final coffee for a few days and see whether the morning puddle disappears.

Does the machine purge when it heats up?

Breville only ties the purge to what happens immediately after the espresso, hot water and steam functions. Nothing in the instruction book describes a purge at power-on. Rapid Heat Up reaches extraction temperature in about three seconds, so there is no long warm-up phase to dump water during.

The steam wand spits water when I lower it. Is that a fault?

No, that is the automatic purge clearing residual milk from the wand, and Breville warns that it can release hot steam when the wand is lowered. Wipe the wand and tip with a damp cloth before returning it to the down position, so the purge has less milk to clear. Keep your hand clear while it runs.

Can I still use the machine while I wait for a new silicone seal?

If the only symptom is espresso escaping around the portafilter edge, the machine is safe to use and simply makes a mess and a weaker shot. If water is reaching the bench or the base, stop and unplug it. Electricity and standing water on a counter is the line where a nuisance becomes a hazard.

How do I tell a group head leak from a tank leak?

Dry everything, then run the hot water outlet with no portafilter fitted. Hot water uses the tank and the pump but not the group head seal. Water appearing at the back or underneath during that test is a tank or connection problem, so start at Fix 3. A dry test followed by a wet bench during extraction points at the group head, so start at Fix 4.
