Rinsing Water Temperature (Max): 85°C. Weight: 125kg. Dimensions (H(open)xWxD) mm: 1480(1960)x700x785. Protection Class: IPX5.
• Page 4: Device dimensions Installation - water connection Plumbing connections must allow the machine to be removed for service and cleaning. Connect the hose supplied with the machine to the inlet at the rear of the machine and the ¾” NPT fitting on the water supply line. Check the water inlet pressure is between 2-4 bar (29-58 psi) (not static). If it is more, a pressure reducing valve must be installed. If it is less, a booster pump will be required. Washing performance depends on external conditions such as water inlet temperature, pressure, hardness, and chemicals used. To increase the service life and washing performance, supply water should be below 9 degree Clark. Otherwise, a water softening device should be fitted. Water inlet temperature: 4-50°C. Any damage resulting from the use of hard water will not be the manufacturer’s or distributor’s liability and voids the product warranty.
• Page 5: Use of detergent and rinse aid in the dishwasher. Your Buffalo Dishwasher has a detergent pump and a rinse-aid pump for use with non-foaming liquid detergent. Insert the hoses of the pumps in the correct chemical container. Ensure both of the hoses are at the bottom of the containers of the chemicals. The chemicals to be used should be suitable for dishwashers. The detergent shall be the no foam type, suitable for glass washing machines. We recommend that you use detergent and rinse aid from the same manufacturer. Detergent amount required is dependent on soil and water hardness. Rinse aid amount required is dependent on water hardness. We recommend the use of a water softener to reduce limescale which can damage your machine.
• Page 6: Priming detergent and rinse aid When using for the first time or if the detergent/rinse aid is allowed to run dry, detergent and rinse aid hoses will be full with air. To prime detergent and rinse aid hoses use the following instructions. Please use this option after the machine has reached the required temperature values. Press and hold the settings icon for 3 seconds. Enter the password “1” by using “up” and “down” buttons. This will take you to the “Detergent filling screen”. To start priming detergent press start/pause button (Hold 3 sec). To prime the rinse aid press and hold the settings icon for 3 seconds. This will take you to the “Rinse Aid filling screen”.
• Page 7: Washing and rinsing water temperatures can be adjusted. The appliance is set to specific temperature values during production. The temperature should not be set higher than these values. To understand the information in the user manual correctly, the main parts of the appliance should be known.
• Page 8: Operation Control panel Before starting the appliance, familiarise operators with the control buttons and signal items on the front panel. Operators should be familiar with the location of power and water cut-off switches. Starting the appliance Make sure that the electricity, water and drain installations are complete. Wait for the “On/Off switch” on the front panel to light, then keep it pressed for 3 seconds. The LCD screen will switch on. The machine will start to take water automatically. Heating starts automatically when the set amount of water has entered the boiler.
• Page 9: When the boiler gets to 60C, heated water is sent to the washing tank. This process continues until the washing tank is fully filled. After the washing tank is fully filled, the machine waits for the boiler and washing tank set temperatures to be reached. When the boiler water temperature reaches 85C and the tank water temperature reaches 55C, the machine is ready for washing. The washing process will not start until the washing tank and boiler reach the set temperature. In order for the water to heat up faster during the process, the machine door must be closed. Accessing the settings menu requires pressing and holding the settings icon for 3 seconds. Use the up and down buttons to enter ‘2’. You will see the password screen. Hold for 3 seconds to confirm.
• Page 10: Changing parameters involves accessing the settings menu and selecting the desired program. The parameters that can be adjusted include tank temperature, boiler temperature, washing time, waiting time after washing, detergent time, rinse aid time, dirtiness counter, tank preheating, and start by door/hood. Each setting is made separately for each program. Waiting time after washing prevents droplets from falling on glasses during rinsing. Detergent and rinse aid times are controlled by timers, affecting the amount dispensed. The dirtiness counter tracks the number of washes until the washing tank water needs to be changed. Tank preheating settings determine whether the washing cycle can start without reaching preset temperatures. The start by door/hood setting controls whether the cycle begins when the door is closed or by touching the control screen.
• Page 11: Preparation for use involves waiting for the supplied water to warm up. The appliance functions efficiently when proper temperatures are reached. If temperatures decrease, wait for the appliance to reach temperature before starting a new wash cycle. Select the appropriate washing program depending on the type of dishes and degree of soiling. The washing process starts by pressing the washing start button. The program time will count down on the LCD display. When the washing program is finished, the machine starts rinsing. If the cabinet door is opened during the washing process, the process will stop. When the door is closed again, the program will continue from where it left off. The machine beeps when the washing process is finished.
• Page 12: Draining Excess water generated during the operation of the machine will be automatically removed via the drain. At the end of each day, the door should be left open to drain and dry. Before the machine is turned off at the end of the day, the boiler water must be completely drained. Models without drain pump (drain by gravity) require removing the drain plug in the tank to start draining. Models with a drain pump have the drain system automatically activated when the rinsing cycle is started. Before turning off the unit at the end of the day, the unit should be drained. After the drain process is complete, it is recommended to disconnect mains water and electrical supply. For a more hygienic operation, leave the appliance door open after the draining process.
• Page 13: Cleaning and maintenance should be carried out by trained personnel in accordance with the safety instructions. Daily maintenance includes disconnecting washing arms and removing debris with water and a nylon brush. Debris remaining in the washing tank should be removed. The suction filter should be disconnected and cleaned with water. The inside of the tank should be cleaned with a sponge or cloth and plenty of water. Periodic maintenance should be carried out by the user at least once a month. Descale the machine by adding descaler to the washing tank and follow descaler instructions. After descaling, drain the water within the machine and refill with fresh water. If the device is not used for a long period, drain the water left inside the boiler. Never use cleaning chemicals containing bleaching agents, chlorine, or hypochloride.

• Page 15: Trouble shooting Unit does not switch on Check mains water and electrical connection is in place and active. Unit does not run when the start button is pressed Ensure that the hood is securely closed. Unit is not heating the wash water Check water is turned on. Ensure inlet water temperature is between 5 and 50°C. Washing tank resistor faulty due to scale Descale the unit. Poor washing performance Check the detergent and rinse aid chemicals. If empty, replace. Dishes being loaded without emptying Remove any left-overs/debris on dishes before loading the basket. White marks on dishes can be caused by hard water Contact your distributor for details on using the necessary water softener. Appliance does not drain Clean the filters. Water intake is slow Ensure water supply is open. Water pressure should be 2-4 bars.
