How to replace the silicone sealing ring of a semi-automatic coffee machine?
Coffee silicone gel equipment maintenance

When making coffee, there is a rubber ring between the coffee handle and the brewing head. This is the sealing rubber ring, which is a very critical accessory to ensure extraction pressure and water leakage!
When should the seals be replaced?If water leaks from the edge of the handle during brewing, or if you need to use a lot of force to get the coffee handle stuck, you need to replace the seal!
Why we need to change the silicone sealing ring?
The sealing rubber ring of the coffee machine will age much faster than the rubber ring at room temperature if it is exposed to high temperature for a long time. Generally, it needs to be replaced every six months. After aging, the rubber ring will lose its elasticity and break, which will lead to insufficient pressure in the handle during extraction, water leakage at the edge of the handle, and espresso will naturally be mixed with water and coffee grounds.

Therefore, facing the problem of water leakage in the sealing ring of the coffee machine brewing head, it is particularly important to adopt timely and effective solutions.
This includes regularly checking and maintaining the status of the brewing head seal. Once it is found to be aging or damaged, it should be replaced with a new seal in time to ensure the stable operation of the coffee machine and the safety of users enjoying a good coffee time .
Brewing head silicone sealing ring replacement steps :
1.Disassemble the brewing head
Before starting to replace the brewing head seal, first make sure that the coffee machine has completely stopped and the power supply has been disconnected. This is to prevent any unexpected situations during operation, such as the coffee machine accidentally starting up and causing injuries to people, or damaging the parts inside the coffee machine. Next, the operator needs to follow the coffee machine disassembly guide and gradually disassemble the brewing head. During the disassembly process, special attention should be paid to the tightening sequence and strength of the screws, because improper tightening sequence and strength of the screws may cause damage to other parts of the coffee machine. Generally speaking, the screws should be removed step by step in a certain order, and do not use excessive force during the disassembly process to avoid damaging the screws or other parts of the coffee machine.
2.Cleaning and inspection
After removing the brewing head, it needs to be thoroughly cleaned and inspected. This is to ensure that there is no dirt and residue on the surface of the brewing head, and there are no damaged or worn parts inside. First, use a cleaning cloth and a special detergent to clean the surface of the brewing head. During the cleaning process, be especially careful not to use a too rough cleaning cloth or too much detergent to avoid scratching or damaging the surface of the brewing head. At the same time, check whether there are damaged or worn parts inside the brewing head. During the inspection, you can observe whether the parts inside the brewing head are complete, cracked or worn, etc. If damaged or worn parts are found, they need to be replaced with new parts in time to ensure the normal operation of the coffee machine and the quality of the coffee.
3.Install new silicone seal ring
After confirming that the brewing head has been cleaned and there is no damage inside, you can start installing the new brewing head seal. The operator needs to apply an appropriate amount of special sealing lubricant to the new seal, which can enhance the fit between the seal and the brewing head and improve the sealing effect. Then install it on the brewing head in the correct position and direction. During the installation process, it is necessary to ensure that the seal fits tightly with the brewing head to avoid the recurrence of water leakage. At the same time, pay attention to whether the installation direction and position are correct, because the seal has two sides, and improper installation may cause water leakage or poor sealing.
4.Assembly and testing
After installing the new seal, reassemble the brewing head to the coffee machine in the reverse order of disassembly. During the assembly process, pay special attention to the tightness of each component and whether the connection is firm and reliable. After assembly, the coffee machine needs to be preliminarily tested to ensure that the brewing head seal is installed correctly and can work properly. During the test, carefully observe whether the coffee machine still has water leakage and taste the coffee to see if the taste and quality have returned to normal. If any problems are found, they need to be adjusted and repaired in time to ensure the normal operation of the coffee machine and the quality of the coffee.
Seal replacement cycle management
Considering that the performance of the coffee machine brewing head seal is a consumable part, it will gradually decline with the passage of time and the increase of usage intensity. It is particularly important to implement strict seal replacement cycle management. Operators should scientifically and rationally formulate a preventive replacement plan for the seal according to the actual frequency of use of the coffee machine, daily workload, working environment and other factors, and strictly follow the plan. The plan should include the specific time point of each replacement, replacement interval and corresponding maintenance records, so as to track and evaluate the use of the seal.
In addition, in order to ensure the long-term stable operation of the coffee machine and reduce operating costs, it is recommended to establish a stock of seal spare parts in advance so that they can be quickly replaced when needed, reducing the risk of machine downtime and service interruption caused by waiting for new parts. At the same time, you can also sign a long-term cooperation agreement with the supplier to ensure the stable supply and technical support of key parts such as seals.
