Daily & Weekly Maintenance Routine for Your Lelit Bianca

Keeping your Lelit Bianca in top condition starts with a consistent maintenance schedule. By building a habit of simple daily and weekly cleaning tasks, you’ll extend the life of your machine, maintain the quality of your espresso, and prevent costly repairs down the line.

Daily Cleaning Tasks

Your Lelit Bianca works hard every day—so it deserves a little TLC after each use. These daily cleaning steps take just a few minutes and help prevent the buildup of coffee oils, milk residue, and mineral deposits.

1. Wipe and Purge the Steam Wand After Every Use
   After steaming milk, immediately wipe the steam wand with a damp cloth and purge it by briefly opening the steam valve. This removes any milk residue that could clog the tip or cause bacterial growth.
2. Flush the Grouphead
   Run a few seconds of hot water through the grouphead before and after brewing. This helps clear out leftover coffee grounds and stabilizes brew temperature for your next shot.
3. Empty and Rinse the Portafilter and Drip Tray
   Knock out the puck and rinse the portafilter under warm water. Also, empty and clean the drip tray at the end of each day to prevent mold and odor buildup.

Daily Cleaning Checklist:

• Wipe & purge steam wand
• Flush grouphead before/after brewing
• Rinse portafilter and basket
• Empty drip tray and wipe surface
• Refill water reservoir if needed

Weekly Maintenance Tips

Weekly cleaning ensures deeper cleanliness and keeps vital components like the E61 grouphead and water system in good shape.

1. Backflush the Grouphead with Water
   Insert a blind filter basket in your portafilter, run the pump for 10 seconds, then stop. Repeat 5–6 times to remove coffee oils from the grouphead and valve system. This water-only method is safe to do weekly.
2. Clean the Grouphead Screen and Gasket
   Use a grouphead brush to scrub around the rubber gasket and metal screen under the grouphead. Remove the screen occasionally for a deeper clean.
3. Rinse the Water Tank and Check Water Levels
   Remove the water reservoir, rinse it with clean water, and wipe the sensors. Always use filtered water to prevent limescale buildup in the boiler.

Weekly Routine Items:

• Backflush with water
• Scrub grouphead with brush
• Remove and clean shower screen
• Rinse & refill water tank
• Check for leaks or signs of buildup

Tools You’ll Need

Having the right tools on hand makes cleaning your Lelit Bianca fast, effective, and less of a chore. These items are recommended for both daily and weekly maintenance:

Essential Tools:

• Soft microfiber cloth – for wiping surfaces and the steam wand
• Grouphead brush – to clean the gasket and shower screen area
• Blind filter basket – for backflushing the E61 grouphead
• Espresso cleaning tablets or powder (e.g., Cafiza) – for monthly backflushing with detergent
• Small bowl or pitcher – for flushing and soaking parts

With these tools and routines in place, your Lelit Bianca will consistently deliver café-quality espresso—and stay as stunning as the day you unboxed it.

Deep Cleaning & Descaling the Lelit Bianca

While daily and weekly cleaning keeps your Lelit Bianca in top shape, deep cleaning and descaling are essential for long-term performance. Since the Bianca is a dual boiler espresso machine, neglecting internal maintenance can lead to limescale buildup, inconsistent temperature, and damaged components. In this section, you’ll learn when and how to descale your Lelit Bianca, properly clean the grouphead, and maintain key parts like the portafilter.

How Often to Descale

Descaling is one of the most important—but often overlooked—tasks in dual boiler espresso machine care. Limescale buildup inside the boiler and water lines can lead to flow issues, heat instability, and even permanent damage if left unchecked.

Here’s how to determine how often you should descale:

• Use soft or filtered water: This greatly reduces the frequency of descaling. Avoid hard tap water unless it’s treated with a softener.
• General rule: Descale every 3 to 6 months, depending on your water type and usage.
• Monitor signs of scale: Reduced steam pressure, strange noises, and slow heating are all signs your machine may need descaling.

Pro Tip: If you use an inline water softener or filter, you may only need to descale once a year.

Step-by-Step Descaling Process

When it’s time to descale your Lelit Bianca, follow this safe and effective routine:

1. Turn off the machine and let it cool if it has been running.
2. Mix your descaling solution (follow manufacturer instructions, e.g., 25–50 ml of descaler per 1 liter of water) and pour it into the water tank.
3. Power on the machine and let it heat to operating temperature.
4. Run half of the descaling solution through the brew circuit by engaging the grouphead for 10–15 seconds, then stopping. Repeat until half the tank is used.
5. Run the remaining solution through the steam wand and hot water tap, pausing every 10 seconds to avoid overheating.
6. Let the solution sit in the boiler for 15–20 minutes to dissolve mineral deposits.
7. Flush the system thoroughly by refilling the tank with clean water and running it through the brew and steam circuits until the water is clear and odor-free.

Important: Always rinse thoroughly. Any leftover descaler can affect taste and damage internal parts.

Table: Lelit Bianca Descaling Schedule

Water Type	Usage Level	Descale Frequency
Filtered	Light (1–2 shots/day)	Every 6 months
Tap (moderate)	Medium (3–5 shots/day)	Every 3–4 months
Hard Water	Heavy (6+ shots/day)	Every 2–3 months

Cleaning the Grouphead and Portafilter

The grouphead is where your espresso is brewed, and over time it collects oils, grounds, and residue that can affect taste and performance. Here’s how to keep it in great shape:

1. Use a grouphead brush to scrub the gasket and around the shower screen daily or weekly. Coffee oils and debris can cause leaks if not removed.
2. Remove and soak the portafilter and basket in a mix of hot water and a coffee cleaning tablet (e.g., Cafiza or Puly Caff) for 15–30 minutes.
3. Rinse all parts thoroughly with warm water and dry completely before reassembling.
4. Re-lubricate the E61 grouphead with food-safe lubricant (optional but recommended every few months) to maintain lever smoothness and seal integrity.

Extra Tip: Remove and clean the shower screen and diffuser screw monthly for a deep clean. These parts often hide behind-the-scenes buildup.

By incorporating this deep cleaning and descaling routine into your maintenance schedule, your Lelit Bianca will continue to deliver rich, consistent espresso—and serve you reliably for years to come.

Long-Term Care and Troubleshooting Tips

Once you’ve mastered daily cleaning and periodic deep maintenance, it’s time to think long-term. To ensure your Lelit Bianca continues to perform like new, it’s crucial to pay attention to components that wear over time—like water filters, electronic controls, and internal seals. This section covers water filter replacement, common troubleshooting tips, and smart habits that help extend your machine’s lifespan.

Replacing the Water Filter

The water filter is one of the simplest yet most important components of your Lelit Bianca’s maintenance routine. Clean water not only improves the taste of your espresso, but also protects your machine’s dual boiler system from scale and mineral buildup.

Here’s what to know:

• Check and replace your filter every 1 to 2 months, depending on usage and water hardness.
• Use Lelit-branded water softening cartridges or a compatible in-tank filter to ensure consistent performance.
• A fresh filter can prevent limescale, reduce mineral deposits, and extend the time between descaling cycles.

Pro Tip: If you notice your espresso tasting flat or bitter, or if your steam power seems weaker than usual, a clogged filter might be the culprit.

Common Issues and Fixes

Even with proper care, occasional problems can arise. The good news is that many Lelit Bianca troubleshooting issues are simple to diagnose and fix at home—without the need for costly service calls.

Here are a few common symptoms and their likely causes:

• Low Brew Pressure
  • Cause: Clogged grouphead, dirty portafilter basket, or puck prep issue
  • Fix: Clean the grouphead thoroughly, backflush with detergent, and check grind size/distribution
• Steam Wand Not Heating Properly
  • Cause: Limescale buildup in the steam boiler
  • Fix: Run a descaling cycle focused on the steam circuit
• PID Controller Not Responsive
  • Cause: Software glitch or power fluctuation
  • Fix: Power off the machine, unplug for 30 seconds, and restart. If issue persists, reset the PID controller or consult Lelit support

Quick Troubleshooting Tips:

How to Extend the Life of Your Lelit Bianca

Want your Lelit Bianca to last 10+ years? Follow these simple habits to preserve your machine’s internal components, avoid damage, and keep it looking showroom-new:

1. Always Use Filtered or Soft Water
   Hard water is the #1 cause of scale buildup and internal corrosion. Using filtered water not only preserves boiler health but enhances espresso flavor.
2. Keep the Machine Dry When Not in Use
   Wipe down the exterior daily, and don’t let standing water sit in the drip tray or under the machine.

   This helps prevent dust from settling into crevices and keeps your polished stainless steel finish looking beautiful.
4. Service Internally at Least Once Per Year
   If you’re comfortable, open the machine to inspect internal hoses, boilers, and wiring for buildup or wear. Otherwise, have it professionally serviced annually.

Bonus Tip: Keep a maintenance log. Tracking when you last descaled, changed the filter, or cleaned the grouphead helps ensure consistent care.
