Why is Nespresso Milk Frother not working? Possible reason
To fix an appliance, figuring out the exact cause of the problem becomes mandatory. We found the top 8 possible reasons for Nespresso frother (also known as an Aeroccino) not functioning correctly.
- Placement of magnetic whisk is improper
- Liquid damaged the electrical components of the machine
- Burst out heating component and thermocouple
- Dirt’s on electrical component contacts
- The type of milk used isn’t suitable for frothing
- Damaged/broken magnetic whisk
- Too much amount of milk is used
- The outlet of the machine is trapped
Let’s now discuss each of these possible reasons, their causes, and solution for how to fix them.
The placement of the magnetic whisk is improper.
A magnetic whisk is that component of the Nespresso milk frother responsible for actual whipping. There are a few different reasons of this piece is not attached properly and is improperly placed, but possibilities can be figured out quickly.
Because of the presence of a magnet inside the whisk, it can be attached to any part of the inside of the frother. This can be complicated because there’s only one place for the machine to work.
If circular light on the front of the machine indicates lit red light, but milk is not spinning inside, then improper placement of magnetic whisk is the possible cause.
Ensure that the magnetic whisk is attached properly to the nipple on the bottom of the frother. Simply pour the milk into a cup, adjust the whisk again, pour the milk again, and you’re done!
Liquid damaged the electrical components of the machine.
Many users can’t realize that they just can’t wash their Nespresso milk frother. If water gets to the bottom of the machine where most electrical components are present, they become wet and eventually stop working.
Nespresso frother comes in 4 parts
- Frother itself
- Magnetic whisk
- Power station
- The lid
You can rinse the magnetic whisk and lid or even put them in the dishwasher. However, you must be careful while rinsing the frother without getting the bottom wet. Additionally, you must be careful to keep the power station away from water to avoid any kind of accident.
Unfortunately, if the milk frother stops working while washing, it’s time to buy a new one because you can’t repair it.
Fortunately, the milk frother is relatively cheap and can be bought online, or you can purchase different components separately if you need them. Still, the bottom line is if you take care of your frother, you will avoid having to replace it. The result: it will last for years!
Burst out heating component and thermocouple
To such components, fixes involve taking components apart and putting them back together again, which is quite hard. This involves dealing with electricity which is too challenging, and there is risks probability of electrocution and fire. Therefore it is highly recommended to seek professional help while dealing with such components.
Burst out Heating Component
The heating component is a copper strip printed on an electric circuit. They are a pretty cheap design choice, and as a result, there are maximum chances of failure for those devices that have been used a lot. It is pretty easy to figure them out and fix them before they cause any severe damage.
Open the container to access the PCB. You will quickly see where the track has burned; that is precisely the culprit. You will fix this by soldering a small strip of copper over where the track got burned. To do this, you had to scrape off some of the glazes to gain access to good copper.
Burst out or damaged thermocouple
The thermocouple is a small electronic device present inside a milk frother. The thermocouple’s function is to monitor the temperature of the milk, and once the optimum temperature is achieved, it will turn off the device automatically.
A damaged or burst-out thermocouple indicates that the desired temperature is achieved even before the operation starts. This means your machine milk frother will turn on and gain turn off immediately without any activity involved.
To resolve this, you will need to replace the thermocouple. This can easily be disconnected from the PCB via a sliding connector. When inserting the new thermocoupleThermocouple, be sure to apply thermal grease to ensure it conducts temperature properly.
Dirt’s on electrical component contacts.
The Aeroccino milk frother gets its power from the round plastic connector located at the bottom of the machine. A presence of female connector on the milk jug and a male connector on the Nespresso machine.
Sometimes it is also a standalone base station based on the Nespresso machine model, but the functionality is the same.
These two connectors tend to accumulate grease, dirt, and milk residue, especially in overflow.
If the machine won’t turn on or seems to be getting power intermittently, that’s probably the possible cause!
Crusted milk residue is the main form of dirt that builds up in the milk frother over some time, especially if you’ve had a few boils. Once dirt begins to build up, it will trap moisture and erode the contacts.
The easiest solution is to thoroughly clean the plate with soapy water and treat the contacts with a contact cleaner.
You will need:
- Soapy water and cloth
- Isopropyl alcohol or methyl alcohol.
- Toothbrush or wire brush.
- Contact spray cleaner.
Start by turning off the machine and unplugging it (just for safety). Turn the nozzle cartridge over and inspect both cartridge and base station connections. Take a small brush and soapy hot water and scrub it thoroughly until you can see the dirt has been removed completely.
A toothbrush is usually a perfect choice for this task and is performed with experts' highly recommended descaling Products and other cleaning products.
