2. Remove the lever from the machine.

Depending on your specific model, you may need to use a wrench or screwdriver to do this. Place the lever aside on a clean surface.

3. Remove any visible dirt or debris from the lever system using a clean, lint-free cloth.

If there are any particularly dirty or sticky parts, you may need to use a cleaning solution specifically designed for espresso machines.

4. Apply a small amount of food-safe lubricant to the piston and the metal surfaces on the grouphead that come in contact with the piston.

Spread the lubricant evenly over the surfaces with a clean, lint-free cloth.

5.Replace the lever back onto the machine, making sure it's properly aligned and tightened.

6.Operate the lever a few times to distribute the lubricant evenly throughout the system.

Listen for any unusual sounds or sensations that may indicate a problem.

7. Wipe down the exterior of the machine with a clean, damp cloth to remove any excess lubricant or dirt.

8. Plug in and turn on the machine, and make a few test shots to ensure that everything is working properly.

If you notice any problems or changes in the taste or quality of your espresso, you may need to troubleshoot further or seek professional help.

9. Depending on your machine and usage, you may need to relube your Rocket Espresso lever machine every few months to keep it running smoothly.

Be sure to check your machine's manual or consult with a professional if you're unsure.

Why it's vital to apply lubricant to your Rocket's lever system

Relubing your Rocket Espresso machine's lever system is important for a few reasons:

  1. Smooth operation: The lever system is a critical component of your Rocket Espresso machine, and it needs to move smoothly and responsively to produce the best espresso possible. Over time, dirt and debris can accumulate on the piston and grouphead surfaces, making the lever system less smooth and causing it to require more effort to operate. Relubing helps to keep these surfaces clean and well-lubricated, ensuring that the lever system operates smoothly and requires less effort.

  2. Durability: Regular relubing can help prolong the life of your Rocket Espresso machine by reducing wear and tear on the piston and grouphead surfaces. Without proper lubrication, the metal surfaces can become scratched and damaged, leading to more frequent repairs and replacements.

  3. Consistent quality: When the lever system operates smoothly and responsively, you'll be able to produce more consistent and high-quality espresso shots. Inconsistent or poor quality shots can be a sign that the lever system is not functioning properly, and relubing can help address this issue.

Overall, relubing your Rocket Espresso machine's lever system is an important part of regular maintenance that can help ensure your machine produces delicious espresso consistently and lasts for years to come.

When should I replace the E61 group head gasket?

The E61 group head gasket is a crucial component in espresso machines that use this type of group head. Over time, the gasket can wear out or deteriorate, which can affect the quality of your espresso shots and potentially cause leaks. Here are some signs that it may be time to replace your E61 group head gasket:

  1. Loss of pressure: If you notice a decrease in the pressure of the water flowing through the group head, it could be a sign that the gasket is worn and needs to be replaced.

  2. Water leaks: If you notice water leaking around the group head, it could be a sign that the gasket has deteriorated and is no longer sealing properly.

  3. Poor espresso quality: If your espresso shots are weak or have a sour taste, it could be a sign that the gasket is not sealing properly and allowing water to bypass the coffee puck.

  4. Visible wear and tear: If you notice cracks or tears in the gasket, it is time to replace it.

  5. Age: Even if you don't notice any obvious signs of wear or deterioration, it is generally recommended to replace the E61 group head gasket every 6-12 months as a preventative measure to ensure optimal performance and prevent potential leaks.

Replacing the E61 group head gasket is a relatively simple and inexpensive task that can be done at home with basic tools. It is important to use a high-quality, food-grade silicone gasket that is specifically designed for the E61 group head to ensure optimal performance and safety.
