2. If the filter is clogged, replace the filter after cleaning.

3. Remove the nozzle, start the machine, and check if the water sprayed from the gun is normal. If the water is normal, install the nozzle and check if the machine has pressure. If there is no pressure, the pressure regulating valve is damaged or damaged than the pump.

4. Check whether the water seal is damaged or worn, and the factors that cause the water seal to wear mainly include: normal wear and tear, wear caused by poor water quality, long-term water shortage operation or long gun time (usually 30 minutes for guns) High seizure wear and need to be replaced at the moment.
