Espresso puck can stick to the group head if the ground distribution is inadequate or the tamping is incomplete. Also, extra-fine grind or excessive brewing pressure in the portafilter can compact the puck and cause sticking.
In this post, we will share how you can loosen a stuck puck from the group head. Moreover, we will discuss some preventive steps to avoid the issue in the future.
Let’s explore.
How to Get Espresso Puck Out from the Group Head
You can apply multiple methods to loosen the stuck puck from the group head. The best one depends on your convenience and comfort. Here we mentioned three common ways to get the espresso puck out.
Method 1: Using the Portafilter
Espresso portafilter can be a handy tool to free the puck from the group head. This method is very practical since the puck falls back into the basket without making things dirty. Here are the steps:
- Position your portafilter directly on the stuck puck.
- Gently move the portafilter back and forth until the puck gets loose.
- When the puck falls into the portafilter, remove it from the group head’s surroundings.
Method 2: Using a Paper Towel
Another alternative method to remove the stuck puck is using a paper towel. This technique is fast and effective without directly touching the puck. But you need to be cautious about the temperature of the puck. Here are the steps:
- Take a clean paper towel in your hand.
- Position the towel against the stuck puck.
- Apply gentle pressure until the puck gets loose and comes out.
Precaution: Ensure the puck is not hot; otherwise, it can burn your palm. To avoid burning, you should not apply this method immediately after an extraction.
Method 3: Running the Shower Screen
This method is the easiest one among the others. It does not require using a portafilter or a paper towel to loosen the stuck puck. Instead, running forced water through the group head will wash out the puck. Here are the steps:
- Remove the portafilter from the group head after extraction.
- Without the portafilter, run water through the group head as if you are extracting espresso.
- The force of water will separate the puck from the group head.
Precaution: Unfortunately, the method can create a mess when the puck falls off. Besides, do not touch the detached puck right after falling since it can be hot.
How to Avoid Espresso Puck Sticking to the Group Head?
Precise ground measurement, using the right accessories and proper cleaning will help prevent the puck from sticking. Here are some tips to follow:
1. Weigh Your Doses
The sticking issue often occurs when you put excessive coffee ground into the portafilter. It is always recommended to measure grounds using a coffee scale before brewing. This step will prevent forming of a compacted puck and the sticking issue.
2. Use the Right-Sized Basket
Using the right tools with accurate dimensions is another way to prevent such incidents. When choosing a portafilter basket, ensure its size is appropriate for your desired espresso shot. Never use a smaller basket and overfill it with grounds. It will increase the risk of sticking.
3. Clean the Group Head Shower Screen Regularly
Keep the shower screen clean to prevent blockage and ensure sufficient water force. For the best outcome, you can back flush to reduce the chance of sticking.
