Cause and elimination: professional repair or replacement.

Reasons and exclusion:

(1) The program controller CAM is damaged; Replace the CAM.

(2) The circuit connection is wrong or loose; Check and correct according to electrical schematic diagram.

Reasons and exclusion:

(1) If there is a humming sound, the motor is stuck, check the impeller or the washing pump has a mechanical fault, to be eliminated.

(2) The pressure switch (water level switch) does not work; Check whether the low-water pressure switch contact is stuck or the pressure is out of alignment.

(3) Motor or capacitor burned; Check whether the motor or capacitor is normal.

Reasons and exclusion:

(1) Power failure or fuse blown, until the power supply is normal or replace the fuse.

(2) Plug, socket loose, power cord broken. Use the resistance gear of the multimeter to check that the circuit breaker is properly connected.

(3) The program controller is faulty, check whether the program controller motor is damaged, whether the contacts are in poor contact, such as poor contact can be sanded.

(4) cut off water supply; Dishwasher is equipped with water level switch, waterless injection motor can not work, until normal water injection before use.

(5) The door is not closed or the door switch is damaged; You can close the door or check whether the switch is damaged, poor contact, etc.

(6) Where the electrical part has a break; Use a multimeter resistance to locate the broken line according to the electrical schematic diagram and secure it.

The solution:

1, the tableware is placed improperly, the number is too much and there is overlap, so that the water can not effectively wash. Should be placed according to the washing capacity of the instructions, there should be a gap between the tableware and avoid overlapping.

2. The water in the sink is too dirty and needs to be changed.

3. The spray hole of the spray arm is blocked, and the water is not smooth; Can remove the spray hole debris.

4, dishwasher selection procedure is not appropriate; The appropriate procedure should be selected according to the instructions.

5, improper use of detergent or too little; Use special detergent and dosage according to instructions.

6, no dishwasher salt, water too hard to soften; Add special dishwasher salt and adjust the softened water system according to the calcium content of the water.

The solution:

1, the drainage pipe is bent or folded, check the drainage pipe to eliminate bending and folding.

2, drainage pump motor failure, repair or replace the pump motor.

3, the filter or pipeline is blocked by foreign matter, remove foreign matter to remove the blockage.

4, circuit board problems, repair or replace the circuit board.

Dishwasher does not refill solution:

1. Check whether the water source is closed.

2, the water supply hose is bent or folded, check the hose to eliminate bending and folding.

3. After manually replenishing water, confirm whether the dishwasher can operate normally, and then notify the engineer for processing.

Reasons and exclusion:

(1) Low water temperature f The water temperature in the dishwasher should not be lower than 55 ~ 65 ° C, if the water is supplied by the water heater or hot water pipe, the water temperature can be appropriately increased.

(2) The water is not hot; The heater of the dishwasher with its own heater is damaged. Use a multimeter resistance to measure whether the heater is burned out or has poor contact.

(3) Low water pressure, long water intake time; Because the water intake time takes up the washing time, the washing and flushing are not normal. Find out the cause of the low water pressure.

(4) The drainage pipe is blocked and the drainage is abnormal; Clean the drain pipe or filter.

(5) improper use of detergent; The use of ordinary detergent will foam affect washing and flushing. Use dishwasher detergent and use as required.

(6) After eating, the residue of the tableware should be removed and then washed in the dishwasher.

(7) Food hard on the tableware can not be washed off; The dishes should be washed in the dishwasher immediately after use.

(8) Overlapping of dishes and dishes to prevent cleaning: should be placed correctly according to the instructions.
