Puly Caff Liquid Descaler for Espresso or Coffee Machines

 

 

What

Descaling is necessary if the espresso machine had accumulated a lot of minerals from the water. It is much better to treat and soften the water than descaling an espresso machine too much.

Severe amount of mineral build-ups can cause sensors to malfunction, creating various issues which can be hazardous. However, we must warn that the descaling agent may not be able to reach the key components to clear off limescale adequately. Users should not be using mineral or Alkaline water for coffee machines.

This product is for any coffee machines, particularly for espresso machines with boilers.
Descaling can be a challenging process. For the best effect with the least damage, it should be done by a qualified technician.

Puly Caff Liquid Descaler for Espresso or Coffee Machines is in liquid form, is food grade and in individual bottles for easier storage.
The liquid version can be used in room temperature water and studied to have the maximum performances and safe on yellow metals boilers (copper, brass) and INOX.
It can work for any type of espresso machines or boilers that need descaling

 

 

When

It is hard to judge when is descaling needed as it depends on the amount of usage and the hardness of the water. For users who diligently soften their water to be good enough for their espresso machine, they may never need to be descaled.

Using a water softener as a preventive measure should be the correct way to go than frequent descaling.
Users can use this product for regular preventive descaling to clear off light layers of build-up.

 

How

The instructions below are for clearing light layers of build-ups along the water circuitry.

If your machine wasn’t purchased from Fine Coffee Company, please refer to your vendor for instructions.

 

Who

For users who want to do light and preventive descaling, it’s possible that the user can do it themselves.
For severe cases, please contact a qualified serviceman.

 

Disclaimer

Do note that the instructions below are not sufficient to clear off a huge amount of limescale or all types of limescale. It is also not possible for the descaler to reach all ends of the machine, especially to the top of the boiler to clear off limescale around key components.

Also be aware that descaling often voids the warranty for most professional machines including those sold by us as descaling is a very erosive process.
It’s not uncommon for problems to arise after descaling. This can happen when bits of limescale can’t dissolve completely but flake off the walls, and end up choking a valve. Or key components that could be damaged in the process, especially if the process was incorrectly done.

We will not be responsible for any damages or hurt that might be possible during the process.
We do not advocate in heavy and frequent descaling, we firmly believe that the correct way is to prevent limescale from building up by using softened water.

Please refer to a qualified technician if you suspect that your machine has a huge amount of mineral build-ups.

 


 

Instructions

The below instructions serve for machines sold by Fine Coffee Company and are not applicable to every brand in the market.

Please refer to your machine’s user instructions for more information.

 

How much to purchase?

The product comes with two bottles of 125ml of Liquid Descaler.
For every 125ml of descaler, mix with 400ml of water.
Thus, two bottles will create a mixture of 1050ml of the descaling agent.

You will need to purchase the amount according to the size of your boiler + 500ml extra for the grouphead.

Examples:
A Bezzera Magica/Mitica, or Strega.
It has a 2 litres boiler with a single grouphead
You will need five bottles of descalers.

A Bezzera BZ13/BZ10
It has a 1.5 Litres boiler with a single grouphead
You will need four bottles of descalers

 

Descaling procedures

Do note that the following descaling instructions, will not fully remove limescale from the machine as the descaler cannot reach the top of the boiler, or reach every corner of the water circuitry.  It will be better than the components located at the top of the boiler, to be either replaced, or inspected during maintenance. A machine should only be using softened water to maintain its internal condition, reducing the likelihood of extensive repairs.

Single Boiler and Heat Exchangers

IMPORTANT FOR VIBRATION PUMPS: KEEP THE INTERVALS OF IT WORKING AT MAXIMUM 30 SECONDS. FOR EVERY 30 SECONDS OF THE PUMP WORKING, REST IT FOR 30 SECONDS.

 

The video below should work for heat exchangers. If your machine is a Strega, skip the part on using a blind filter.

Draining the boiler.
1. Heat up machine regularly till it’s ready and pressurised.
2. Switch off the machine and immediately drain the boiler by releasing water from the water wand. If there’s no water wand, release from the grouphead followed by the steam wand.

Filling boiler with descaling agent
3a. If the machine has a water tank.
i) Replace the water in the tank with an appropriate amount of descaling agent.
3b. If the machine doesn’t have a water tank and can only draw water from a water network.
i) Get ready a water container that can store the amount of descaling agent.
ii) Disconnect water hose from the water network and place hose into the water container containing the descaling agent.
4. Switch on the machine. The machine should draw the descaling agent into the boiler.

 

REMINDER AGAIN!

IMPORTANT FOR VIBRATION PUMPS: KEEP THE INTERVALS OF IT WORKING AT MAXIMUM 30 SECONDS. FOR EVERY 30 SECONDS OF THE PUMP WORKING, REST IT FOR 30 SECONDS.

 

5. Flush about 10 seconds of water out from the grouphead, steam wand and water wand.
6. Insert a blind, pressurise the grouphead with descaling agent drawn from the water tank for 5 times. [NOT FOR BEZZERA STREGA, NEVER USE A BLIND FILTER FOR STREGA!]

7. We will suggest not leaving the agent in the espresso machine for more than 30 minutes.

 

Rinsing with clean water
8. Repeat step 1-2 to drain all the descaler out of the boiler
9. Replace water tank with a tank of clean softened water. Make sure the water tank was cleaned first.
10. Switch on the machine to draw clean water into the boiler

 

REMINDER AGAIN!

IMPORTANT FOR VIBRATION PUMPS: KEEP THE INTERVALS OF IT WORKING AT MAXIMUM 30 SECONDS. FOR EVERY 30 SECONDS OF THE PUMP WORKING, REST IT FOR 30 SECONDS.

11. Repeat step 5, 6, 8, 9 and 10 for one to two more times if necessary.

It is not possible to fully drain out the descaler from the boiler. If you wish to know if you had flushed enough to get rid of the descaler from the boiler. Simply draw some water from the boiler, sprinkle some baking soda on it, it should not fizz. For a short moment of time after descaling, the water may seem to have more bubbles or have a light odour. The descaler is food grade and will diminish after a period of usage.

It is important to remember that vibration pumps should not work for 2 minutes without 1 minute of rest. Rotary pumps should never run without water passing.

Double Boilers

We will suggest requesting for professional help due to complications.

 

 

WARNING:

1. NEVER allow your pump to activate for more than 120 seconds and work for too long with rest time, it will damage the pump.

2. DO NOT perform descaling and grouphead flushing with detergent back to back or together.

3. Flakes of scales and impurities may cause technical issues after descaling. Fine Coffee Company will not guarantee and does not warrant user’s machines from malfunctioning after descaling.
