The Fellow Aiden Precision Coffee Maker is a remarkable piece of coffee engineering that delivers café-quality brews right to your kitchen. Like any precision instrument, it requires proper care and maintenance to keep performing at its best. This comprehensive guide will walk you through everything you need to know about maintaining your Aiden, with specific advice tailored for UK water conditions and UK-available products.
Why Regular Maintenance Matters
Your Aiden contains sophisticated temperature control systems, precision water pumps, and internal heating elements that work together to create the perfect brew. Over time, mineral deposits from tap water can accumulate inside the machine, affecting water flow, brewing temperature, and ultimately the taste of your coffee. Regular maintenance ensures your Aiden continues to deliver consistent, delicious coffee for years to come.
Understanding UK Water Hardness
One of the most critical factors affecting your Aiden's maintenance requirements is the hardness of your tap water. The UK has significantly varied water hardness depending on location. Parts of the south and south-east experience very hard water (over 200 mg/l), whilst some areas, particularly in Scotland and Wales, have softer water.
Why this matters: Hard water contains higher concentrations of calcium and magnesium minerals. When this water is heated inside your Aiden, these minerals crystallise and form scale deposits. The harder your water, the faster scale will build up and the more frequently you'll need to maintain your machine.
To find out your water hardness, contact your local water supplier directly. Most water companies in the UK provide this information on their websites or via customer service. Knowing your water quality is the single best way to determine your maintenance schedule.
Daily Maintenance: After Every Brew
Time required: 5-10 minutes
This is the most important maintenance routine. Taking just a few minutes after each brew prevents long-term issues from developing.
Start by allowing the Aiden to cool slightly, then open the filter box lid and remove the filter basket by pulling up on the handle. Discard the used coffee grounds and paper filter into your compost bin or waste. Rinse the filter basket thoroughly under running water to remove any remaining grounds. If you want a more thorough clean, the basket can go straight in the top rack of your dishwasher.
Next, wipe the filter nest (the area where the basket sits) with a soft, damp cloth to remove any stray grounds or coffee residue. This prevents material from falling into the water system. Ensure the showerhead is clean and free from grounds. Place your basket back in position and close the lid.
After every few brews, wash the thermal carafe, lid, and any removable parts with warm, soapy water. Rinse thoroughly and dry completely before storing. The carafe's double-walled design keeps coffee hot without needing a heating plate, so it's crucial to keep it clean.
Weekly Deep Clean
Time required: 15 minutes
Once weekly, take a closer look at areas that might accumulate residue. Wipe down the exterior of the Aiden with a soft, damp cloth to remove any dust or spilt coffee. Pay particular attention to the water tank area and the base of the machine.
Remove the water tank and rinse it thoroughly under running water. If you use the same water source regularly, minerals might start accumulating here, too. A gentle wipe with a damp cloth inside the tank helps prevent buildup. Make sure the tank is completely dry before refilling.
For this weekly clean, also inspect the shower head more carefully. Remove it by turning the selector in the middle clockwise. Look at the underside—if you notice any scale deposits (which appear as chalky, crusty buildup), this indicates that descaling might be needed sooner than the machine's automatic reminder suggests.
Monthly Flush Cycle
Time required: 10 minutes
Once a month, run a flush cycle through your Aiden's maintenance menu. Access this by going to Settings > Maintenance > Flush on your machine's display. This cycle forces clean water through the internal lines to help prevent scale accumulation between descaling sessions.
This is particularly important if you have hard water. The flush cycle helps break up mineral deposits before they become problematic and cause issues like the "Add Water" message to appear incorrectly.
Quarterly Descaling: The Critical Maintenance Task
Time required: 30-40 minutes
This is where proper maintenance really becomes important. Descaling removes accumulated mineral deposits from your Aiden's heating system and internal water lines.
When to Descale
Your Aiden automatically reminds you to descale after 150,000 ml of water has passed through it. However, UK water hardness means you likely need to descale more frequently:
- Soft water areas (Scotland, Wales, parts of the Midlands): Descale every 3-4 months or when prompted
- Medium hardness areas: Descale every 2-3 months or when prompted
- Hard water areas (London, south-east, south-west): Descale every 4-6 weeks or when prompted
If you notice any of these signs, descale immediately: the "descale" reminder appears on the display, water flow has slowed, the "Add Water" message appears when the tank is full, or your coffee tastes off.
How to Descale Your Fellow Aiden
You'll need:
- A high-quality, biodegradable, phosphate-free coffee machine descaler
- Fellow recommends Urnex Liquid Dezcal, which is readily available in the UK through online retailers
- A container to catch the descaling solution
- 30-40 minutes of uninterrupted time
Important: Do not use vinegar. Whilst it's tempting to reach for household vinegar as a budget option, it's difficult to rinse thoroughly from the machine and can affect the taste of subsequent brews.
Step-by-step:
-
Ensure the batch brew filter basket and carafe are in position and empty. Remove any coffee or filters from the basket.
-
Empty the water tank completely and rinse it.
-
Mix your descaling solution according to the manufacturer's instructions (typically around a 1:10 ratio of descaler to water). Check your descaler packaging—Fellow's concentrate, for example, provides clear dilution ratios.
-
Pour the prepared descaling solution into the water tank up to the MAX fill line.
-
Place an empty container under the carafe outlet to catch the used solution.
-
Select Descale Mode from your Aiden's display by navigating to Settings > Maintenance > Descale.
-
The descaling process runs in three cycles: approximately 16 minutes, then 10 minutes, then 10 minutes. Between each cycle, the display prompts you to empty the carafe and refill the tank with clean water.
-
Important timing note: You must complete each empty and refill stage within 5 minutes of the cycle finishing, or the Aiden will go to sleep and won't count the descaling as complete.
-
After the entire process finishes, empty the carafe completely and rinse it very thoroughly.
-
Run three complete brew cycles with clean water and no coffee to flush out any remaining descaling solution. This ensures no descaler residue affects your next brew.
If you receive an "Add Water" message during descaling (common with heavily scaled machines), let the solution sit in the tank for 5-10 minutes and try again. You may need to repeat this a few times to completely clear stubborn scale.
Filter Changes and Supplies
Frequency: Weekly or as needed
Your Aiden comes with 15 cone filters for single-serve brewing and 15 flat-bottom filters for batch brewing. These can be purchased at www.coffeebeautiful.co.uk.
Keep a stock of filters on hand so you're never without when you need a brew. Whilst the exact interval depends on your brewing frequency, most users find they need to reorder filters monthly.
Water Quality and Prevention
The best maintenance is prevention. Here are some strategies to reduce scale buildup:
Use filtered water: Standard carbon filters (like those in jugs or fridge filters) don't significantly reduce water hardness. However, they can improve the taste and reduce some debris from entering your machine. If you're in a hard water area, consider investing in a water softening system or reverse osmosis filter for your Aiden.
Avoid certain water types: Don't use distilled water or true reverse osmosis water exclusively. Whilst these have zero minerals (preventing scale), they can actually damage your Aiden's internal components over time by dissolving the protective minerals in metal parts. If you use these, add minerals back using Third Wave Water packets (available in the UK).
Don't use mineral or spring water: Despite the premium connotations, mineral-rich water causes faster scale buildup than tap water, which can actually accelerate your maintenance needs.
Keep the machine clean: Prevent coffee grounds and chaff from entering the water system by keeping the area around your Aiden clean. Cover the water tank when not in use to prevent debris from settling in it.
Firmware Updates and App Maintenance
Your Aiden connects to WiFi and can receive automatic firmware updates. These updates improve performance and add new features.
To ensure regular updates
- Download the Fellow app on your iOS or Android device
- Connect your Aiden to your WiFi through the app
- Leave it connected for at least 24 hours to ensure the latest firmware downloads
- Check Settings > About > Version on your machine to confirm you're running the latest version
These updates are important for maintaining peak performance and accessing the latest maintenance features, including improved flush cycles and better scale detection algorithms.
Annual Inspection: When to Seek Help
Whilst most maintenance can be handled at home, once annually (or if you notice problems), perform a thorough inspection:
- Check that the thermal carafe lid seals properly
- Inspect the water tank for any cracks
- Ensure the showerhead selector rotates smoothly
- Verify that the dial responds smoothly to input
If anything feels loose, damaged, or doesn't function smoothly, contact our customer experience team through our website. We provide excellent support and can advise on repairs or replacement parts.
Seasonal Adjustments for the UK
Summer: If your machine sits unused during the summer months, run a full descaling and flush cycle before using it again. Stagnant water can allow scale to form even without the machine operating.
Winter: Hard water can contain more minerals during winter. If you notice increased descaling reminders during colder months, this is normal. Don't reduce your maintenance frequency.
Your Maintenance Schedule at a Glance
- Daily: Empty grounds, rinse basket, wipe filter nest
- Weekly: Deep clean exterior, rinse water tank
- Monthly: Run flush cycle
- Every 4-6 weeks (hard water) to every 3-4 months (soft water): Run full descale cycle
- Quarterly: Inspect all removable parts
- Annually: Full inspection and warranty check
