The drip tray is the least glamorous part of an espresso machine and the first place you notice when cleaning slips: stale coffee water, white scale rings, and a musty smell. It is also the easiest part to keep clean, because the habit takes less than a minute.
Emptying and rinsing the tray daily prevents almost every tray problem.The Direct Answer: Daily Empty, Weekly Wash
The drip tray collects three things: stale water from flushes, coffee residue, and occasionally milk drips. Left together, that mix develops odor and, in warmer kitchens, mold. Scale is a slower problem: hard water evaporating from the tray leaves white mineral rings that etch the surface.
The routine is simple: empty and rinse the tray daily as part of the machine's shutdown, then wash it with warm soapy water weekly or when visible residue appears. Two minutes a day removes nearly every drip tray failure mode.
Why Mold and Odor Happen Faster Than You Expect
Espresso water, even clean water, carries coffee oils and sugars that bacteria and mold feed on. The tray is dark and usually warm from sitting under the machine, which accelerates growth. Milk makes it worse, because dairy residue spoils quickly and smells before anything else in the kitchen.
The odor usually appears from the tray's corners and the float sensor area, where liquid sits undisturbed. If the machine starts to smell stale even when the beans are fresh, the drip tray is the first suspect, long before any internal part.
Cleaning Frequency, by Use
| Habit | Frequency | What it prevents |
|---|---|---|
| Empty and rinse tray | Daily | Odor, stale water, float sensor issues |
| Wash with soapy water | Weekly | Milk residue, coffee oils, mold |
| Remove scale rings | As they appear | Etching and surface buildup |
| Check float and sensor | Monthly | Accurate full-tray warnings |
| Dishwasher sanitize | Per manual | Deep cleaning if the tray allows it |
If you flush the group or purge steam into the tray often, check it mid-day rather than waiting for shutdown. Milk in the tray deserves same-day washing, not a weekly schedule.
The Step-by-Step Routine, Done Right
End each session by removing the tray, emptying it into the sink, and rinsing it with warm water. Wipe the tray cavity in the machine too, because water and grounds collect there and feed the same odor. Weekly, wash the tray with warm soapy water, paying attention to the corners, the float, and any drain slots.
For scale rings, use a soft cloth with a mild cleaner or a descaling product made for the tray material, then rinse thoroughly. Avoid abrasive pads that scratch the surface, since scratches become the next spot for residue to cling to.
A clean float keeps the full-tray warning honest.Signs You Skipped It
A musty smell near the machine, a sticky tray surface, dark film in the corners, or scale rings that no longer rinse off all mean the schedule slipped. A tray warning that never triggers despite visible water usually means the float is stuck under residue, which is a cleaning fix, not a sensor fault.
The float matters more than it looks: if the sensor cannot move, the machine may not warn you about a full tray, and overflow ends up on the counter. Cleaning the float area monthly keeps that safeguard working.
Drip Tray vs. Machine Cleaning: Knowing the Boundary
The drip tray is surface maintenance, not machine maintenance. Backflushing, descaling, and wand cleaning protect the internal brew path; the tray protects the kitchen and the machine's exterior. Both matter, but they run on different schedules and solve different problems.
Do not try to clean a dirty tray by running a cleaning cycle, since that cleans the group, not the tray, and do not assume a cleaned tray means the machine internals are clean. Track them as separate items on your routine.
Deep-Dive: Common Edge Cases and What to Try Next
Two situations come up regularly. First, stubborn odor after washing: soak the tray in warm water with a little cleaning solution or the manual's recommended cleaner for 15 minutes, then rinse, and check the tray cavity once more since residue hides there. Second, scale that keeps returning within days: that is a hard-water signal, and the fix is water treatment upstream, not more aggressive tray scrubbing.
If your machine sits in a humid environment, drying the tray before reinserting it helps, and leaving the tray out overnight once a week lets the cavity air out. Small habits, but they are the ones that keep the machine area smell-free.

FAQ
How often should I clean my Breville drip tray?
A practical baseline is emptying and rinsing the tray daily, and washing it with warm soapy water weekly or whenever milk or coffee residue dries in it. If you flush the group or steam into the tray often, it will need attention more frequently.
What can I run through my espresso machine to clean it?
Run only what the manual specifies: water for flushing, the recommended cleaning powder for backflushing, and the recommended descaler for descaling. Avoid vinegar and other improvised cleaners, which can damage seals and leave residues.
Can I use vinegar to descale my Breville?
Generally no. Manufacturers specify a descaler and procedure for a reason: vinegar's acidity and residue can attack seals and leave a lingering taste. Use the product the manual names, and rinse thoroughly after descaling.
Do I need to clean my espresso machine after every use?
Not a full clean, but a minute of daily hygiene is realistic: purge the steam wand, wipe the group and portafilter, and empty or rinse the drip tray. Deep cleaning and descaling happen on a schedule, not daily.
Keep the machine area odor-free in two minutes a day. For Meraki-specific cleaning steps and tray care, check the support page or call +1 833 854 9555 (Mon-Fri, 9 AM-5 PM EST).
Cleaning frequencies vary by machine, use, and water hardness. This guide is a practical baseline; always follow your model's official manual for tray care, cleaning products, and dishwasher safety.
