The hand-held high-pressure cleaner can be divided into three types: cold water, hot water and steam. The cold water cleaner can only be cleaned cold water, while the hot water cleaner can be cleaned with both hot water and cold water, which is a dual-purpose model. Hot water high-pressure cleaners have a special in removing oil stains and are suitable for cleaning equipment and oil-stained pipelines in food processing, feed processing, chemical and other enterprises. During the use of the cleaning machine, is inevitable that there will be faults. When problems arise, the cause should be carefully found out according to different fault phenomena. Common faults and solutions of hot water high-pressure: 

Fault one: the spray gun does not spray water

1. The water inlet and water inlet filter are blocked;
2. The nozzle is;
3. The heating spiral tube is blocked, and the scale should be removed when necessary.

Fault 2: Unstable water pressure
1. Insufficient water supply;
2. Air intake into the pipeline due to reasons such as pipelineupture and the detergent suction nozzle not being inserted into the detergent;
3. Nozzle wear;
4. Leakage of the seal the high-pressure water pump.

Fault three: burner does not ignite combustion
1. Insufficient air intake, white smoke;
2. Dirty and clogged fuel filter fuel pump, fuel nozzle;
3. Change in the position of the ignition electrode, too weak spark;
4. Damaged solenoid valve;

5. Damaged high-voltage ignition coil;
6. Damaged pressure switch.

If the above problems occur in the high-pressure cleaner, you can find the cause and eliminate the fault by yourself. However, if the cleaner has serious faults as leakage of the pump body and leakage of the crankshaft housing, the cleaner should be sent to a professional maintenance department with complete spare parts and strong technical force for repair so as to avoid unnecessary economic losses.
