troubleshooting:

   During the use of the cleaning machine, it is inevitable that there will be failures. When a problem occurs, the cause should be carefully searched according to different fault phenomena. 1) The spray gun does not spray water a) The water inlet and the water inlet filter are blocked. b) The nozzle is clogged. c) The heating coil is blocked, remove the scale if necessary. 2) Unstable outlet pressure a) Insufficient water supply. b) The air is sucked into the pipeline due to the rupture of the pipeline, the cleaning agent nozzle is not inserted into the cleaning agent, etc. c) Nozzle wear. d) High-pressure water pump seal leaks. 3) The burner does not ignite and burn a) The air intake is insufficient, and white smoke is emitted. b) The fuel filter, fuel pump and fuel nozzle are dirty and clogged. d) Solenoid valve is damaged. e) The position of the ignition electrode changes and the spark is too weak. f) The high voltage ignition coil is damaged. g) Damage to the pressure switch.

  If the above problems occur in the high-temperature and high-pressure cleaner, the user can find the cause and troubleshoot by himself. However, if the washing machine has serious faults such as water leakage from the pump body and oil leakage from the crankcase, the washing machine should be sent to a professional maintenance department with complete accessories and strong technical force for repair, so as to avoid unnecessary economic losses.
