This appliance is for indoor use only, for household use only. Please unplug before cleaning and maintaining the appliance. This appliance must be earthed to reduce the risk of electric shock.
Page 4: Important safety instructions should be followed when loading items to be washed. Sharp items should be located to avoid damaging the door seal. Knives and utensils with sharp points must be loaded with points down or placed horizontally. Check that the detergent powder is empty after the wash cycle. Do not wash plastic items unless marked dishwasher safe. Use only detergent and rinse additives designed for automatic dishwashers. Children should be supervised to prevent them from playing with the appliance. The door should not be left open to reduce the risk of tripping. If the supply cord is damaged, it must be replaced by a qualified person. This appliance’s packaging materials are recyclable and should be disposed of properly.
Page 5: Quick operation guide Switch off the appliance when the working cycle has finished; the buzzer will sound 8 times, then stop. For detailed operating method, read the corresponding content in the instruction manual. Switch on the appliance by opening the door and pressing the On/Off button. Fill the detergent dispenser in Compartment A with each wash cycle. The appliance will power off automatically after 30 minutes without any operation. Unload the appliance starting from the lower basket and wait about 15 minutes before unloading to avoid handling hot dishes. Check the rinse aid level using the mechanical indicator or electric indicator on the control panel. Scrape off any large amounts of leftover food before loading the baskets. Select a programme by pressing the Programme Button until the selected programme lights up. To add forgotten dishes, open the door slightly to stop the dishwasher, then add the dishes and close the door to resume operation.
Page 6: Operation instruction The water softener must be set manually, using the water hardness dial. The water softener is designed to remove minerals and salts from the water. The softener should be adjusted according to the hardness of the water in your area. The dishwasher is designed to allow for adjustment in the amount of salt consumed. Please follow the steps below for adjustment in salt consumption. Before using your dishwasher for the first time, set the water softener. Add 1.5kg dishwasher salt and then fill the salt container with water. Fill the rinse aid dispenser. The manufactory setting is H4 (EN 50242). Contact your local water board for information on the hardness of your water supply.
Page 7: Prior using for the first time If your model does not have any water softener, you may skip this section. The hardness of the water varies from place to place. If hard water is used in the dishwasher, deposits will form on the dishes and utensils. The salt container must only be refilled when the salt warning light in the control panel comes on. The appliance is equipped with a special softener that uses a salt container specifically designed to eliminate lime and minerals from the water. Always use the salt intended for use with dishwashers. The rinse aid is released during the final rinse to prevent water from forming droplets on your dishes. Only use salt specifically designed for the use in dishwashers. Rinse aid is automatically added during the last rinse, ensuring thorough rinsing, and spot and streak free drying. You should never let the rinse aid level fall 1/4 full. Immediately after filling the salt into the salt container, a washing program should be started.
Page 8: Prior using for the first time, new pulverised detergent is typically without phosphate, so it is recommended to fill salt in the salt container even with low water hardness. Using detergents without phosphate in hard water can lead to white spots on dishes; adding more detergent may improve results. Detergents without chlorine may not completely remove strong and colored spots; using a higher temperature program is advisable. Detergents can be categorized into conventional alkaline detergents and low alkaline concentrated detergents with natural enzymes. To use the rinse aid dispenser, turn the cap to the open arrow, fill it carefully, and replace the cap securely. Detergent tablets dissolve at different speeds; longer programs are recommended to ensure complete removal of detergent residues. The detergent dispenser should be refilled before each wash cycle, typically requiring only one tablespoon of detergent for a normal load. The rinse aid dispenser has adjustable settings; starting at setting 4 is recommended, adjusting higher if spots or poor drying occur. Detergents are essential for removing dirt and transporting it out of the dishwasher; most commercial quality detergents are suitable for this purpose. Only use branded detergent specifically made for dishwashers, keeping it fresh and dry, and add it just before starting the wash cycle.
Page 9: Prior using for the first time Consider buying utensils which are identified as dishwasher-proof. Use a mild detergent that is described as ‘kind to dishes’. Dishwasher detergent is corrosive; keep it out of reach of children. For particular items, select a program with as low a temperature as possible. To prevent damage, do not take glass and cutlery out of the dishwasher immediately after the program has ended. Fill the detergent dispenser with detergent. Please observe the manufacturers dosing and storage recommendations as stated on the detergent packaging. Scrape off any large amounts of leftover food; it is not necessary to rinse the dishes under running water. Place objects in the dishwasher in a way that allows the spray arms to rotate freely during washing.
Page 10: Loading the dishwasher baskets involves specific guidelines for optimal cleaning results. The height of the upper basket can be adjusted to create more space for large utensils. Very small items should not be washed in the dishwasher as they could easily fall out of the basket. Load hollow items such as cups and glasses with the opening facing downwards to prevent water collection. Dishes and items of cutlery must not lie inside one another or cover each other. Long bladed knives stored upright are a potential hazard; they should be positioned horizontally in the upper basket. Do not overload your dishwasher for good results and reasonable energy consumption. To prevent water dripping from the upper basket into the lower basket, empty the lower basket first. Cutlery should be placed in the cutlery basket with handles down, and sharp utensils should have the sharp point down. Pots and serving bowls must always be placed top down, and deep pots should be slanted to allow water to flow out.
Page 11: Starting a washing program involves several steps, including loading the dishwasher and selecting the appropriate cycle. It is recommended to load the lower basket first, then the upper one. Pour in the detergent before starting the wash cycle. Ensure the power supply is connected and the water supply is turned on. Press the ON/OFF button to turn on the appliance. Select the desired wash program by pressing the program button. A cycle can only be modified if it has been running for a short time. If a program is selected, the response light will indicate the selection. A forgotten dish can be added before the detergent cup opens. The dishwasher will resume operation after closing the door.
Page 12: Starting a washing program At the end of the wash cycle, the buzzer of the dishwasher will sound for 8 seconds, then stop. Turn off the appliance using the ON/OFF button, shut off the water supply, and open the door of the dishwasher. The filter prevents larger remnants of food or other objects from getting inside the pump. Wait for a few minutes before unloading the dishwasher to avoid handling the dishes and utensils while they are still hot. The filter system consists of a coarse filter, a flat (main filter), and a micro filter (fine filter). Food and soil particles trapped in the main filter are pulverized by a special jet on the lower spray arm and washed down to drain. Larger items, such as pieces of bones or glass, are trapped in the coarse filter. This fine filter holds soil and food residues in the sump area and prevents it from being redeposited on the dishes during the wash cycle. For best performance and results, the filter must be cleaned regularly. The dishwasher must never be used without the filters.
Page 13: Maintenance and cleaning are essential for the dishwasher's performance. Inspect the filters for blocking after every use. Remove the filter system by unscrewing the coarse filter and clean it under running water. Regularly clean the spray arms to prevent clogging from hard water chemicals. The entire filter assembly should be cleaned once a week. After every wash, turn off the water supply and leave the door slightly open. Use a lightly dampened cloth to clean the control panel and dry it thoroughly. Avoid using sharp objects or abrasive cleaners on any part of the dishwasher. When cleaning the door, only use a soft warm, damp cloth. To prevent odours, run an empty wash cycle before unplugging the appliance.
Page 14: Installation instruction The aesthetic wooden panel could be processed according to the dimensions illustrated. The installation of pipes and electrical equipment should be done by professionals. Disconnect electrical power before installing the dishwasher to avoid electrical shock. The installation position of the dishwasher should be near the existing inlet and drain hoses and power cord. Choose a place near the sink to facilitate the installation of inlet and drain hoses. If the dishwasher is installed at the corner of the cabinet, ensure there is space when the door is opened. Install the hook on the aesthetic wooden panel and fix the panel onto the outer door by screws and bolts. Ensure there is less than 5mm between the top of the dishwasher and cabinet. Maintain a minimum space of 50mm for the door of the dishwasher.
Page 15: Installation instruction Tension adjustment of the door spring The door springs are set at the factory to the proper tension for the outer door. If aesthetic wooden panels are installed, you will have to adjust the door spring tension. Adjust the tension of the door springs by using an Allen key turning in a clockwise motion. Door spring tension is correct when the door remains horizontal in the fully opened position. Connect the inlet hose to the cold water supply. Connect the drain hose. Affix the condensation strip under the work surface of the cabinet. Level the dishwasher. The dishwasher must be secured in place.
Page 16: Installation instruction Dishwasher must be level for proper dish rack operation and wash performance. Level the dishwasher by adjusting the three levelling legs individually. Improper connection of the equipment-grounding conductor can result in the risk of an electric shock. The appliance must be connected to the water mains using new hose-sets. Water pressure must be between 0.04 MPa and 1 MPa. Do not use an extension cord or an adapter plug with this appliance. Ensure the Aquastop safety supply unit is in a vertical position once installed. Connect the cold water supply hose to a threaded 3/4(inch) connector. This appliance must be earthed to reduce the risk of electric shock. Please close the hydrant after using.
Page 17: Installation instruction Position the appliance in the desired location. The dishwasher is equipped with water supply and drain hoses that can be positioned either to the right or the left sides. Review the charts on the following pages may save you from calling for service. Make sure the dishwasher is turned on and the door is closed securely. Check that the water supply is connected properly and water is turned on. If the sink is 1000mm higher from the floor, drain excess water from hoses into a bowl or suitable container. The following things should be checked before starting the dishwasher: the dishwasher is level, the inlet valve is open, and the power is switched on. Use only the special dishwasher detergent to avoid suds. Always wipe up rinse-aid spills immediately. To clean the interior, use a damp sponge with dishwasher detergent and wear rubber gloves.
Page 18: Troubleshooting Improper loading can lead to issues with cleaning and drying. Load the dishwasher as suggested in the directions. Rust stains on cutlery may indicate items are not corrosion resistant. Increase the amount of rinse-aid if there are issues with drying. Always run the quick wash programme after adding dishwasher salt. Do not empty your dishwasher immediately after washing; allow steam to escape. Unsatisfactory drying results may be due to a loose lid on the softener. Rearranging items in the basket can resolve knocking noises from the spray arm. Select a more intensive programme if the dishes are not clean. Error codes will display to warn you of malfunctions and possible causes.
