Moka Pot Only Steam
A moka pot can steam without brewing coffee if a gap exists between the water reservoir and the top lip of its funnel. Besides, it can occur because of over-packed coffee grounds and brewing coffee at low heat.
In this post, we will explain each reason and share how you can prevent only steaming issues.

3 Common Reasons behind the steaming issue
Let’s check out three reasons usually responsible for the moka steaming only issue.
1. A gap between the water reservoir and the top lip of the funnel:
A moka pot brews coffee based on the pressure mechanism. Sometimes, a gap may exist between the water reservoir and the funnel’s lip which can break the air seal. As a result, sufficient pressure cannot be generated inside the moka pot. In such a case, the moka pot will produce steam only but no coffee.
2. Over-packing the coffee grounds:
Experts suggest not packing coffee grounds too tightly into the moka pot’s funnel. If you do, it can hamper the natural flow of water through the funnel. When the pressurized water does not have sufficient space to flow, it can only produce steam without brewing coffee.
3. Using a low heat source:
Moka pots require an ideal temperature to brew coffee. If the temperature provided by the heat source is too low, it will fail to boil the water. Thus, the optimal pressure to push the water through the funnel will not be produced. As a result, your moka pot can only make steam but no coffee.
How to Troubleshoot To Find the Actual Cause of the Steaming Issue
If you are unsure what is causing the problem, you should apply some troubleshooting techniques like the following.
a. Use hot water in the base:
The steaming issue can commonly happen if the temperature of the base chamber is insufficient to produce steam pressure. In this case, you can fill the base chamber with preheated water instead of room-temperature water.
b. Adjust the heat:
If the brewing temperature is too high or low, it can cause the only steaming issue without brewing coffee. So, you should also monitor whether the heat is ideal for brewing. You can adjust the temperature (increase or decrease) to see if it fixes the issue.
c. Watch the brewing with the lid open:
Perhaps, you have found nothing that is producing steam only. Are you curious to see what is going on inside the moka pot? If yes, brew the coffee with the lid open. This technique will help you check the water flow through the filter. Besides, you can identify whether the moka pot has a blockage issue.
At the first attempt, you may not find out the source of the issue. However, keep your patience and your experiment running.
How to prevent the moka pot only steaming problem
The steaming only issue is preventable if you know the actual reasons. Here are some tips to avoid the problem.
1. Check out the seal before brewing:
Ensure no gap exists between the water reservoir and the funnel’s top lip. This inspection will help you to have optimal pressure in the base chamber, which is crucial for perfect brewing.
2. Use the proper heat source:
The best heat sources for moka pots are gas stoves, electric stoves, and hot plates. Though moka pots are usable on the campfire and wood stoves, open flame heat sources like them are not recommended.
3. Clean the Moka pot after each use
Most moka pot issues are relevant to the lack of proper cleaning. Coffee oils and debris can clog the funnel if they are not cleaned after use. It can lead to a malfunctioning moka pot which is the source of various issues.
4. Replace damaged parts
Like other tools, the seal and funnel of a moka pot will be worn-out over time. This can prevent the proper flow of water, a common reason for moka pot only steaming. As a user, you should check them routinely and replace them if damaged.
FAQs on moka pot only steam
You can use a moka pot on a campfire or a wood stove. But open flames like them can damage your moka pot. Besides, you cannot control the temperature for optimal brewing on such heat sources.
A perfect pressure in the base chamber of a moka pot is connected to the quality of coffee. Pressure plays a major role in extracting the flavor and aroma of coffee grounds. If your moka pot cannot generate optimal air pressure, it means the brewed coffee will be dull in taste.
You should place the moka pot directly on a heat source so that its base sits on the stovetop quite well. This position will help to boil water accurately and create the air pressure for brewing coffee.
Final words
If your moka pot just produces steam but no coffee, it can be a frustrating experience. Fortunately, some easy troubleshooting and preventive steps can fix the issue quickly. The above tips and tricks should help you fix the issue at home. However, if nothing works, it might be a manufacturing fault. In such a case, you should contact the manufacturer.
