• Replace the check valve.
• Replace the PAC filter.
• Measure the high pressure pump water pressure, replace.
• Replace the check valve.
• Replace the high pressure switch.
• After checking the check valve, check whether
there is water leakage in the pipelines.
After the machine is
filled with water, the
machine starts repeatedly
The pure water flow is
small or not flowing
