ou are using your high-pressure cleaner as usual, but suddenly it starts jerking! Unfortunately, this is one of the most common problems of a high-pressure cleaner, easily solved with good maintenance and a few
small tricks! Let’s find out about them together!
What does it mean when a high-pressure cleaner goes jerky?
The high-pressure cleaner is an excellent product for daily and extraordinary cleaning of outdoor surfaces and pavements, outdoor furniture, cars, scooters, bicycles, swimming pools, barbecues and much more.
To ensure that you always get maximum performance from this equipment, proper periodic maintenance should be carried out by emptying the internal hydraulic system of residual water, cleaning the filters, storing it properly and making sure that all components are intact after each use. Otherwise, it may happen that some of the most common problems occur, such as that your high-pressure cleaner goes jerky, that is, when the jet is not constant but is more or less intense, with some pressure drops or short stops.
What are the most common causes why a high-pressure cleaner goes jerky?
Some of the most common causes for which a high-pressure cleaner jerks are:
- Problems with the pump, not allowing proper water supply during use;
- The presence of air bubbles in the hose;
- Blockages inside the filter or nozzle;
- Water leaks in the hose, gun, lance or nozzle;
- Power supply problems, such as damage inside the power cord;
- Engine overheating. In this case, the high-pressure cleaner performs an auto-shutdown to prevent damage to internal components.
How to solve the problem if the high-pressure cleaner goes jerky
If your high-pressure cleaner jerks, here’s how to fix the problem:
- If the problem is the pump, check for bottlenecks or sharp bends in the supply hose. If the pump appears to be defective, you may need to take action by changing some of its parts. In this case, we recommend that you contact an authorized service center;
- To remove air bubbles in the hose, disconnect it and let water run through it for a few seconds. After that, make sure to reconnect it properly and verify that the issue is fixed;
- In case of blockages, clean the filter thoroughly and remove any debris from the nozzle. If it is too worn, we recommend removing and replacing it with a new component;
- Carefully check all components for water leaks in the hose, spray gun, nozzle or lance. If there are cracks or holes, the part may need to be replaced;
- If you identify damage in the power cord, avoid using the high-pressure cleaner until you have repaired the damage;
- Should the motor overheat, allow the high-pressure cleaner to cool down before using it again. In case the problem recurs frequently, it is advisable to check if the cooling valves are also well cleaned and operational. If the problem persists, it will be necessary to have the high-pressure cleaner checked by a trained technician to prevent further damage.
How to prevent malfunctions inside a high-pressure cleaner
In order to prevent malfunction or damage inside a high pressure cleaner, we recommend carrying out its periodic maintenance.
In particular, we always recommend:
- reading the printed or digital manual for your model carefully and thoroughly. In this way it will be possible to know its every characteristic, thus preventing any critical issues over time as well as wear and tear;
- carrying out proper cleaning after each use. In particular, clean all components, remove water from the hydraulic circuit and accessories, and store the equipment properly;
- scheduling extraordinary cleaning jobs. In particular, we recommend contacting a specialized technician after 3 months/200 hours of use and after 6 months/300 hours of use. In this case, the technician will then examine and properly clean some of the internal components essential to the proper operation of your equipment, such as the intake and control valves, filters, nozzles and oil.
By properly maintaining your high-pressure cleaner, you will always get the best results for deep, thorough and fast cleaning without stress or fatigue.
