Why does the gun on a pressure washer leak?
If the gun on the pressure washer leaks, the same problem arises as with any other defect that must be located and repaired. The gun must be opened in any case, which is not easy in all cases. It becomes really difficult when a kind of “no-name” product does not offer the possibility to organise spare parts.

Repairable and disposable guns
Pressure washers can be divided into two groups. Gun-type units, which are made of listed spare parts and can be repaired by opening them. Closed and sometimes riveted constructions are only listed as a coherent single spare part.
As a tendency, the design can be made dependent on the price. The more expensive a pressure washer is, the more likely it is that the gun can be repaired and the individual spare parts are available. To repair the gun of the pressure washer, about 15 individual parts inside have to be taken into account and the housing has to be checked for leaks.
Most frequent cause of leakage
A gun often leaks due to just one small thing. The O-sealing ring on the hose connection is a typical wearing part that causes the high-pressure cleaner to become defective.
| Potential Cause | Explanation | Possible Solution |
|---|---|---|
| Worn or damaged seals | Over time, the seals inside the gun can wear out or become damaged, causing leaks. | Replace the seals with new ones designed for your pressure washer model. |
| Loose connections | Improperly tightened connections between the gun, hose, or lance can result in water leakage. | Ensure all connections are securely tightened. |
| Faulty trigger mechanism | A worn-out or faulty trigger mechanism may fail to properly shut off water flow, leading to continuous leaks. | Replace or repair the trigger mechanism following the manufacturer’s instructions. |
| Damaged or clogged nozzle | A damaged or clogged nozzle can cause irregular water flow and result in leaks. | Inspect and clean the nozzle, or replace it if necessary. |
| High water pressure | Excessive water pressure can strain the gun’s components and cause leaks. | Adjust the pressure settings within the recommended range for your pressure washer. |
| Improper use or handling | Rough handling or accidental drops can cause internal damage or misalignment, resulting in leaks. | Handle the gun with care and follow the manufacturer’s instructions for proper use. |
If you have checked the above factors and the gun continues to leak, there may be other underlying issues or a more complex problem. In such cases, it is recommended to consult the manufacturer’s manual or contact their customer support for further assistance. They can provide specific troubleshooting steps or advise on any necessary repairs or replacements.
Regular maintenance of the pressure washer gun can also help prevent leaks. It is good practice to inspect the gun, seals, and connections periodically for any signs of wear or damage. Cleaning the gun after each use and storing it in a clean and dry environment can contribute to its longevity and prevent potential leakage issues.
Remember, safety is paramount when handling a pressure washer gun or any related equipment. Always follow the manufacturer’s instructions, wear appropriate protective gear, and ensure that the pressure washer is turned off and disconnected from the power source before performing any maintenance or troubleshooting.
By addressing the potential causes of gun leakage and taking appropriate measures to rectify them, you can maintain a well-functioning pressure washer gun and avoid water leaks during your cleaning tasks.

Sometimes no sources of supply for spare parts known
No-name products or very cheap own brands, such as those offered by discounters, do not always offer sources for spare parts, especially for older units. However, it is always worthwhile to research similar models. The design and construction of the pistols are similar in some manufacturers and by having a second pistol you can use it as a kind of individual spare parts store.
When ordering a new gun, pay attention to the two crucial dimensions, the cross-sections of the hose connections. For double security, measuring with a caliper and explicitly mentioning it during the ordering process saves a costly and time-consuming return. Also pay attention to special connection types such as quick or click connections. They must be compatible. Some manufacturers offer additional adapters.
