The Übermilk One
Producing delicious, high quality, milk foam with the Übermilk is a breeze.
But strict adherence to cleaning and monitoring protocols is essential for Irish users to ensure your unit continues to perform optimally.
Irish dairy cattle can be grass-fed most months of the year. And as a result our milk is some of the best in the world. But as a consequence, fresh Irish milk is much higher in fat and protein than fresh milk in other markets. This means consistently monitoring and cleaning are crucial to ensuring the optimal, long-term performance of your Übermilk.

The Importance of the Morning Rinse Cycle for Your Übermilk ONE ON TOP (Ireland)
Why Perform a Morning Rinse Cycle?
Starting your day with a Morning Rinse Cycle is a simple yet crucial step in maintaining the performance and longevity of your Übermilk ONE ON TOP. This daily procedure helps to minimise the risk of milk solid buildup inside the element, ensuring consistent foam quality and preventing potential issues down the line. Think of it as "waking up" your Übermilk and preparing it for a day of service.
What Does the Rinse Cycle Do?
Overnight, any stubborn milk residue that may have been trapped inside the element can loosen and break free after soaking in water. The purpose of the Rinse Cycle is to flush out this residue before you begin using the Übermilk for the day.
How to Perform the Morning Rinse Cycle:
Run several rinse cycles: We strongly recommend running multiple rinse cycles every morning.
Observe the dispensed water: Carefully observe the water being dispensed into a clear container.
Continue rinsing until clear: Continue running rinse cycles until the water dispensed is completely clear of any milk residue before proceeding to the Flow Test.
What to Look For in the Dispensed Water:
The appearance of the dispensed water will provide valuable insights into the cleanliness of your element.
"Normal" Milk Residue:
Description: You may notice small, light-coloured particles in the water. This is normal and expected.
Example of normal milk residue released following a rinse cycle at the start of the day.
Action: Continue running rinse cycles until the water is completely clear.
Darker Milk Solid Residue (Baked-On Solids):
Description: If you see darker, brownish particles in the water, this indicates the presence of baked-on milk solids inside the element.
Example of long-term, baked-on milk solids
Action: Follow these steps:
Continue rinsing repeatedly: Continue to rinse repeatedly until the water dispensed is completely clear.
Proceed to the Flow Test: Once the water is clear, proceed to the Flow Test step and carefully record the results.
Check the Variance (%) figure:
If the Variance (%) is below 3.0%: You may proceed to milk intake and daily use.
If the Variance (%) is above 3.0%:
Run the End-of-Day Cleaning Cycle again.
Repeat steps 1 and 2 above.
If the Variance (%) is still above 3.0%, run the Intensive Cleaning Procedure immediately.
What to Do If Issues Persist:
If, following these procedures, your variance figures have not improved, please contact us immediately at support@workflow.coffee
Understanding and Using the Übermilk ONE ON TOP Flow Test Log (Ireland)
Why is Flow Testing Important for Irish Übermilk Users?
Due to the unique composition of fresh Irish milk, which often has higher fat and protein content, regular monitoring of your Übermilk ONE ON TOP's performance is essential. These milk solids can build up quickly and affect foam quality, temperature, and dispense speeds. Consistent flow testing, using our Flow Test Log, helps prevent blockages, extends the lifespan of your pump, and ensures consistently excellent results. This is why recording accurate and accessible daily flow tests is highly recommended.

What Does the Flow Test Log Help You Monitor?
The Flow Test Log is your primary tool for tracking the health of both your Übermilk pump and element. By consistently recording your flow test results, you can identify potential issues early and take proactive steps to maintain optimal performance. Think of it as a "health check" for your Übermilk.
Example: WORKFLOW Übermilk ONE ON TOP Flow Test Log (Ireland)
Understanding the Columns in Your Flow Test Log
Let's break down each column in the Flow Test Log and explain what it tells you about your Übermilk's performance:
Date: The date the flow test was performed.
Time: The time the flow test was performed. (Consistent timing each day will provide the best comparison data.)
Cold (G): The volume (in grams) of milk dispensed through the cold water line.
Hot (G): The volume (in grams) of milk dispensed through the heated element.
Total Volume (G): This is the sum of the Cold (G) and Hot (G) readings (Cold + Hot). This figure reflects the overall health of your pump.
What to Watch For: This figure should remain relatively stable from day to day.
Troubleshooting: A significant drop in Total Volume (G) may indicate:
A blockage in or leading to the pump.
Milk solid buildup inside the element.
Variance (%): This column displays the percentage difference between the cold and hot milk flow rates, calculated as:
((Cold (G) - Hot (G)) / Cold (G)) * 100. This figure reflects the health of your element.What to Watch For: Figures can fluctuate slightly, but the Variance (%) should never exceed 3.0%.
Troubleshooting: A Variance (%) of 3.0% or greater indicates a likely buildup of milk solids or minerals within your element.
Initials: The initials of the person performing the flow test.
Taking Action Based on Your Flow Test Results
| Metric | Threshold | Recommended Action |
|---|---|---|
| Total Volume (G) | Significant Drop |
|
| Variance (%) | Greater than 3.0% |
|
Important Considerations for Accurate Flow Testing:
- Consistency is Key: Perform the flow test at the same time each day, using the same type of milk.
- Water Quality: Be aware that variations in your local water quality can impact element performance.
- Cleaning Products: Use only WORKFLOW-recommended cleaning products. [Link to Cleaning Products on WORKFLOW site]
- Training: Ensure all staff members are properly trained on how to perform the flow test and interpret the results.
Adjusting Milk Foam Density on Your Übermilk ONE ON TOP (Ireland)
Why Adjust Milk Foam Density?
The Übermilk ONE ON TOP allows you to fine-tune the density of your milk foam, ensuring you can create the perfect texture for a variety of coffee beverages. Whether you prefer a velvety microfoam for latte art or a thicker, more voluminous foam for cappuccinos, these adjustments will help you achieve consistent results.
Understanding the Needle Valve:
The needle valve controls the amount of air that is mixed with the milk, which directly affects the foam density. It's located [Describe location - e.g., on the side of the machine, near the pressure gauge].
Important Notes Before You Begin:
- Small Adjustments: Only minor adjustments to the needle valve should be necessary.
- Test Dispenses: You will need to dispense 100-150ml of milk each time you make an adjustment before the texture of the milk will change noticeably.
Step-by-Step Adjustment Process:
- Remove the blue protective cap: This protects the needle valve from accidental adjustments.
-
Release the needle valve's lock nut: This allows you to make adjustments to the valve.
Releasing the needle valve's lock nut by turning it counter-clockwise.
Action: Turn the ring at the back of the valve fully counter-clockwise (to the left) to release the lock nut before attempting to adjust the front valve. -
Adjust the Main Valve:
- To DECREASE air flow (for thinner, silkier milk/microfoam): Turn the main valve clockwise (to the right).
- To INCREASE air flow (for fluffier, more voluminous milk foam): Turn the main valve counter-clockwise (to the left).
-
Test and Refine:
- Dispense 100-150ml of milk to observe the effect of your adjustment.
- Repeat steps 3 and 4 until you achieve your desired foam level.
-
Lock the Needle Valve:
Once you have found your desired foam level, turn the lock nut clockwise (to the right) to lock your needle valve into position. - Reattach the blue protective cap: This prevents accidental adjustments during service.
Troubleshooting:
- No Change in Foam Density: Ensure that the lock nut is fully released before making adjustments. Make sure you are dispensing enough milk (100-150ml) to see the effect of the adjustment.
- Valve Too Loose: If the valve feels too loose after releasing the lock nut, ensure that you are only making minor adjustments.
By following these steps, you can easily adjust the milk foam density on your Übermilk ONE ON TOP and create the perfect texture for all of your coffee beverages.
Übermilk users in Ireland face far greater cleaning challenges due the high quality of fresh Irish milk.
In addition to following daily cleaning and monitoring protocols, we highly recommend carrying out the Intensive Clean procedure (as a preventative measure) every 4 weeks. Regardless of whether Flow Test results indicate buildup.
The Intensive Clean procedure can also be run in situations where Flow Test results indicate milk solid build up in excess of recommend parameters and daily cleaning and rinsing cycles do not improve flow test results.
Please review the Übermilk Detergent Safety Data sheets prior to carrying out this procedure to ensure proper handling,
The Intensive Cleaning Procedure can be carried out using either Detergent #1 or Detergent #2. We recommend firstly starting with Detergent #1 and then immediately alternating to Detergent #2 in cases of stubborn build up.
NEVER LEAVE UNDILUTED DETERGENT INSIDE THE ÜBERMILK FOR LONGER THAN ONE HOUR
NEVER LEAVE UNDILUTED DETERGENT INSIDE THE ÜBERMILK OVERNIGHT
SEVERE RESIDUE BUILD UP
In cases of severe build up - where residue may be baked onto the inside surface of the element - a single Intensive Cleaning cycle may not suffice.
If after the initial Intensive Cleaning Cycle your variance figure still indicates build up, we would recommend running additional Intensive Cleaning Cycles - but at this point alternating between using Detergent #1 and Detergent #2. 60 minutes each, back to back.
In extreme cases, you may need alternate detergents a few times if the buildup has been severely baked into place. If following this procedure your variance figures have not improved, please contact us immediately at support@workflow.coffee
