WashR PRO | Why is my pressure washer leaking?

The WASHR PRO unit can sometimes develop leak at the earlier stage, particularly from the oil seals and the manifold seals. This usually happens if the unit isn’t properly depressurized before use. When there’s trapped air inside and you start using the unit right away, those air bubbles will seek the easiest way out, which often means finding the weakest material around, like the seals on the manifold or, even more concerning, the seals that keep oil separate from water. To prevent this, it’s a good practice to always depressurize the gun while the unit is switched off. Taking about 20-30 seconds to do this will help ensure everything runs smoothly. Remember to do this each time you use the unit for the first time of the day.
