Terminology (Electronics) It pulls out the water collected at the bottom of the dish water and sprays with top/bottom nozzle through path of each part. It pulls out contaminated water outside the dish washer It is located in the flow path and heats the water flowing through. It emits the internal high temperature moisture outside the dish washer to dry the dishes. It measures the amount of water supplied → It counts the pulse of Hall IC at the entrance of the valve. It is located within the Sump Ass’y, and blocks the water flowing to the bottom and sprayed. It automatically supplies detergent and rinse inside the dish washer at designated times. → Operates 1 minute after the start (Uses heat expansion of paraffin)

As a type of duct, it is the water path to middle and top frame Path that connects the pressure of internal air expanded from high temperature to the external atmosphere

  18. Reference – 3. Q & A on non-error problem (1) Q1. Isn’t dishwasher less hygienic compared to the manual washing? Bacteria living inside the cutting board, kitchen cloth and knife, the bacteria living on the rubber gloves and bacteria such as food poisoning, cholera, influenza do not disappear unless you do a UV process or boil it. General dish washers kill bacterial by heated washing at 70°C or above . Also, since the dishes are inside the closed space, it is much hygienic without any contact with the external dust. Q2. How to I pick the dishwasher for my family? It is good to decide the size considering whether the family enjoys Western food or Orient food etc., how frequently the family eats, whether both of the couple work, preference and number of members by family etc., Check the number of dishes and then decide the size. Q3. Isn’t the washing time too long? When the dish washer operates, it takes about 2 hours from wash to rinse and dry. And most products require 2 hours ~ 2 hours and 30 minutes. Q4. Do I have to use exclusive detergent and rinse? If you use common detergent, it can generates too much bubbles and will put pressure on the machine or discolor the dishes. Therefore you must use automatic dishwasher detergent and rinse. Q5. Isn’t there a way to save detergent and rinse?   Amount of detergent used once is 15g and amount of rinse is 1.5mL for 1 use. If you are using an appropriate amount, a 3KG detergent and 500ml rinse will let you use for 6.5 months and 11 months. You can buy dishwasher detergent on TV shopping, hyper market and department store etc., and use in small amounts by using a separate container to use it for a long time.

  19. Reference – 3. Q & A on non-error problem (2) Q6. Is it cleaner than manual dish washing? Dishwasher is cleaner than washing manually. The water force that comes out of the pump not only remove the food remaining but also removes any stains on the dishes that cannot be spotted by the naked eye. And antibacterial drying kills the bacteria which cannot be done by manual dish washing. Q7. Do I have to use the rinse?  Rinse increases the dry effective of the dishes and prevents minor scratches on the dishes through a coating effect. Q8. Do I have to do the pre-wash?   By pre-washing, you can reduce the number of washes for the filter inside the dishwaster to improve the washing performance. Therefore, it is good to do a pre-wash for a cleaner wash. Q9. How do I have to arrange the dishes to wash effectively?   It is best to line the dishes up in order as shown in the user manual to have the improved washing capability and reduce damage on the dishes. Q10. Isn’t the amount of water used to wash the dishes once too much? The average amount of water used for manual dish washing is about 50~60 liters. But if you use the dishwasher, you will only use about 16L per use, which will save your water utility cost and help the environment. Q11. How many times does the unit rinse by cycle? The number of times for rinsing differs by each cycle. The unit rinses 3 times for normal, heavy, smart auto, and 2 times for delicate, quick and 1time for Rinse.

  20. Reference – 3. Q & A on non-error problem (3) Q12. Can I directly install the dishwasher? When installing the dishwasher for the first time, you must get a specialized engineer’s support. When reinstalling the dishwasher, you can install the unit by referring to the installation manual. When requested to a specialized engineer for reinstallation, a separate installation fee will be charged. Q13. How do I add the detergent? Insert the amount of detergent for 1 wash in the dispenser (detergent container) on the dishwasher door and the close the lid. Q14. The dry condition is not good after the wash. Check whether there is enough rinse and refill the rinse. The rinse dispenser can be set from 1~4 stages with the high number meaning more amount of rinse. Q15. You will hear a “Tak” sound from the product 2-3 minutes after the start. Is this a problem? The dishwasher automatically dispenses the detergent. For normal operation, turn on the power button to start washing. And then the dispenser starts to operate 3 minutes after the start to open the cover. This is the sound of cover opening and hitting the door. This sound is not a problem and is a normal sound that occurs when the detergent is released to the dishes. Q16. When I press the operation button, it drains the water. Is this a problem? This is not a problem. Q17. How do I clean inside the dishwasher? You can wipe inside the dishwasher with a kitchen cloth. Also you can use the exclusive detergent without any dishes and run the cycle to maintain the cleanness.

  21. Reference – 3. Q & A on non-error problem (4) Q18. Does the wash detect the amount of dishes before running the wash cycle? Wash cycle does not detect the amount of dishes. When you select “Smart Auto” source, it detects the level of contamination to automatically and sets the wash time. Q19. Food remaining are still on the dishes after the wash. Is this a problem? This is not a problem. Check whether the nozzle is clogged. Separate the top and middle nozzle to remove any alien particles in the nozzle hole. Q20. The cleaning noise is very large. Check whether the product is leveled properly. And check whether the dishes do not hit the top and middle level nozzles. Q21. Can I change the cycle during the cycle? Yes you can. First press the Start/Stop button to pause the operation and then choose the cycle button you would like to change to and press the Start/Stop button again. At this time, the newly selected cycle will start with the draining sound. Q22. Up to how many hours can I set the reservation? The reservation time increases by 1 hour every time you press the Reservation button, and it can be set to maximum of 24 hours.

  22. Reference – 3. Q & A on non-error problem (5) Q23. I smell something burning when I run the dishwasher for the first time after my purchase. This is the smell from the non-harmful insulation blocker that wraps the external wall of the inner stainless steel plate being closely pressed by the heat generated by the dishwasher. This is the same principle as purchasing a new car for the first time. Q25. Is it ok to use the hardened detergent? Most of the detergent sold are in powder shape. It is created by evaporating the liquid material turning it into power type. Therefore when the power detergent is left exposed to liquid or moisture, it can easily cling to one another to get hardened. This is not a problem in using this detergent. Q26. The stainless steal within the dishwasher changes and is this ok? The stainless steel inside the dishwasher does not have any problems. But depending on the water quality of the area, the amount of Ca.Mg etc. inside the water can deteriorate the shine of the stainless steel. At this time, do not put the dishes on the rack and run the dish washer with 100cc of vinegar to resolve this issue. Q27. I smell something from the dishwasher. Dishwasher is a product that wipes the food from the dishes. The food every household consume is different and the smell is also different. When putting the dishes in the dishwasher, remove any large pieces of food from the dishes. Insert detergent without loading dishes, and run the normal cycle to clean the dishwasher.

  23. Reference – 3. Q & A on non-error problem (6) Q28. How do I insert rinse aid? When you open the door, you will see a round handle at the center of the right side of the dispenser. Turn the handle in the CCW direction to pull out the lid. Then put an appropriate amount of rinse and then turn the handle in CW direction while pressing the lid to lock it. At this time, you must wipe any rinse if you have dripped any. It can cause a great amount of bubbles to cause problems to the dishwasher. Q29. How to I adjust the amount of rinse used? When you open the lid of Q28, you can see the scale of 1, 2, 3 and 4 in the inner side. The arrow is set to either 1 or 2. If the water hardness is high (hard water) and causes deterioration to the surface of the dishes, turn the arrow to 3 or 4. Q30. Can’t I just set the wash/rinse/dry time as I want them? Dishwasher is a device that cleans dishes and is different from the washer. It is programmed to clean dirty dishes with the most appropriate amount of energy used to reach the optimal condition. If you select your own wash time, it will be difficult to rinse bacteria and detergent remaining that are hard to see, and in result will have a negative effect on the user. Therefore we have not created a program to separately control the cycle.
