A guide to cleaning your coffee machine
Quick Coffee Machine Cleaning Tips
- Maintain your coffee machine daily by knocking out used grounds, rinsing the portafilter basket, wiping the steam wand immediately after use, and triggering the auto-purge.
- Execute the 6-minute cleaning cycle when the clean light flashes, and run the 90-minute descale process whenever the orange warning light shows.
- Separate your dishwasher-safe items from the handwash-only parts to protect performance and maintain a great-tasting coffee.
The Best Way to Clean Coffee Machine Models Daily
To maintain an easy clean coffee machine routine, rinse the portafilter and basket after every single brew. Wipe down the steam wand immediately with a damp cloth, then push it back into the down position to trigger the automatic purge cycle, preventing internal milk blockages..
Old ground coffee oils oxidise quickly, turning them sour. When you don’t clean your coffee machine, that flavour pours right into your next espresso. Residual build-up can also create internal pressure issues over time, meaning your appliance may not last as long as you’d hoped..To do this right, you need to treat daily maintenance as a non-negotiable ritual. Rule number 1 is to clean your coffee machine components immediately after your final morning drink. Failing to do so might brew up more than just sour espresso. According to our 2 become 1 campaign, household cleanliness habits are a massive flashpoint for new cohabiters, with uncleaned appliances causing arguments for over 50% of couples who move in together. To keep the peace, opt for easy-to-clean appliances with our moving in guide.
Daily Coffee Machine Cleaning Routine
Follow this rapid post-brew routine for daily cleaning:
- Extract the portafilter and remove the basket. Wash both thoroughly under warm running water.
- Wipe the external surfaces of the steam wand with a clean, damp microfibre cloth right after frothing.
- Push the steam wand back down without the jug present. This triggers the automatic internal purge. You can also manually hit the PURGE button.
- Detach the frothing whisk from the milk jug and handwash it with standard washing-up liquid and warm water.
For a deeper weekly refresh of the steam assembly, fill your milk jug with clean water and a single drop of liquid dish soap. Dock the jug and run the "THIN" froth programme to clear any hidden residue.
How to Deep Clean a Coffee Machine
To properly clean coffee machine scale build-up, fill the water reservoir to the descale line using Ninja Descale Solution or 475ml of white vinegar mixed with water. Fasten the portafilter, position a 535ml container beneath the group head, and press the “DESCALE” button.
Limescale deposits reduce heating efficiency. Hard water creates calcium blockages that alter extraction temperatures and damage internal valves. We advise running this cycle the moment the orange descale light illuminates on your coffee machine.
Neglecting the scale light causes erratic water flow and sour coffee. This automated 90-minute sequence restores your system to peak mechanical operation.
Step-by-Step Descale:
- Empty the main drip tray fully to prevent unexpected overflows during the flush phases.
- Place a 535ml container under the group head. Position your milk jug on its dedicated platform with the steam wand resting inside.
- Pour in your chosen descaling agent. If using white vinegar, add exactly 475ml first, then fill up to the designated descale line with fresh water.
- Click the double basket into the portafilter, lock it into the group head, and place an empty cup (minimum 530ml capacity) underneath.
- Press the DESCALE button, then press the centre dial to initiate.
The control panel displays a countdown timer as it flushes solution through the wand and group head. Once the machine finishes and beeps, remove all vessels with extreme caution. The collected water will be hot. Handwash the portafilter, drip tray, and milk jug with warm, soapy water to wipe out any remaining sour descaling solution. Finish the process by locking the portafilter back in and running a medium-plus size classic brew with clean water, alongside a final manual steam wand purge.
Running the Six-Minute Coffee Machine Clean Cycle
Execute the six-minute coffee machine clean cycle whenever the dedicated clean light flashes. Fill the water tank to max capacity, place the cleaning disc and one specialised tablet inside the double basket portafilter, lock it in, and press the CLEAN button followed by the dial.
The descale cycle only removes mineral scale. It does not dissolve trapped coffee grounds or bitter oils baked onto the shower screen. To clear those away, you must run this automated cleaning. This redirects hot water under pressure back through the group head assembly to scour the internal brewing mechanisms.
Step-by-Step 6-Minute Clean:
- Empty the drip tray completely; the backflush dumps sediment and waste directly into the base.
- Fill the water reservoir right up to the “Max Fill” line.
- Seat the cleaning disc firmly into the double basket with its small handle pointing upwards. Place one cleaning tablet directly in the centre.
- Secure the portafilter into the group head and place a catch cup underneath.
- Press the CLEAN button, then push the centre dial to start the 6-minute flush.
When the unit emits a completion beep, unlatch the portafilter. Look closely at the cleaning disc. If the tablet has not fully dissolved, repeat the steps immediately without adding a new tablet. Handwash the tray and portafilter components in warm water before brewing your next espresso.
Approved Dishwasher Safe vs. Handwash Components
Not every piece of your machine handles the high heat of a dishwasher, so ensure you wash your components appropriately:
| Dishwasher Safe Components (Top Rack Only) | Strict Handwash Only Components |
|---|---|
| Funnel | Portafilter |
| Frothing Whisk | Single & Double Filter Baskets |
| Cleaning Disc | Main Machine Exterior Shell |
| Water Reservoir | Milk Jug |
| Bean Hopper | |
| All Drip Tray Components |
The Next Steps Framework
Protect your investment and guarantee taste excellence by adding these cleaning processes to your normal kitchen routine.
- The Orange Indicator Rule: Never ignore the rising orange float on your drip tray. Empty it the second it becomes visible to stop stagnant water from pooling.
- Immediate Wand Care: Wipe and purge the steam system within five seconds of removing your milk pitcher. Dairy hardens instantly under intense heat.
- Monthly Chemical Flush: If your local water profile features heavy mineral content, don't wait for the automated lights. Clean the group head every 30 days to stop blockages before they manifest.
