Why Karcher Pressure Washer Detergent Not Working
1. Insufficient Pressure
If the pressure washer is not producing enough pressure, the detergent will not be able to reach the surface of the object being cleaned and will not be effective. This can be caused by a number of factors, including:
Dirty or clogged filter:
The filter prevents dirt and debris from entering the pressure washer pump. If the filter is dirty or clogged, it will restrict the flow of water and reduce the pressure.
Low water pressure:
The pressure washer needs a consistent supply of water at a high pressure in order to work properly. If the water pressure is too low, the pressure washer will not be able to produce enough pressure to clean effectively.
Defective pump:
The pump is the heart of the pressure washer and is responsible for generating the pressure. If the pump is defective, it will not be able to produce enough pressure to clean effectively.
2. Wrong Detergent
Not all detergents are created equal. Some detergents are designed for specific types of surfaces, while others are not. Using the wrong detergent can prevent the detergent from working properly and can damage the surface being cleaned.
3. Improper Detergent Application
The way you apply the detergent can also affect its effectiveness. Detergent should be applied to the surface being cleaned before you start spraying with the pressure washer. This will allow the detergent to have time to work on the surface and loosen the dirt and debris.
4. Detergent Clogging
Detergent can clog the nozzles on the pressure washer, preventing the water from flowing out of the nozzle and reaching the surface being cleaned. This can reduce the effectiveness of the detergent and can damage the pressure washer.
5. Detergent Degradation
Detergent can degrade over time, especially if it is not stored properly. Degraded detergent is less effective and can damage the pressure washer.
