TECHNICAL INSTRUCTIONS: These are intended for the qualified staff who are to install, commission and test the appliance and carry out any servicing and repairs. INSTRUCTIONS FOR THE USER: These provide recommendations for use, a description of the controls and the correct procedures for cleaning and maintaining the dishwasher. 1 1 Precautions for safety and use THIS MANUAL IS AN INTEGRAL PART OF THE DISHWASHER AND MUST ALWAYS BE KEPT WITH THE APPLIANCE. POSITIONING, CONNECTIONS, COMMISSIONING, TROUBLESHOOTING AND REPLACEMENT OF THE POWER SUPPLY CABLE MUST BE CARRIED OUT BY SKILLED STAFF. THE DISHWASHER IS INTENDED ONLY FOR PROFESSIONAL USE BY TRAINED STAFF. IT IS DESIGNED TO WASH TABLEWARE (PLATES, CUPS, BOWLS, OVEN DISHES AND CUTLERY) AND SIMILAR ITEMS IN THE RESTAURANT AND INSTITUTIONAL CATERING SECTOR, AND COMPLIES WITH THE INTERNATIONAL STANDARDS ON ELECTRICAL AND MECHANICAL SAFETY (CEI-EN-IEC 60335-258/61770) AND ELECTROMAGNETIC COMPATIBILITY (CEI-IEC-EN 55014-1/-2, 61000-3;4, 50366). [. . . ] As an alternative an external dispenser can be fitted, making the electrical connection by means of an H05 RNF 2x0. 5 mm electrical cable, which can be laid along the route shown in the TECHNICAL DATA diagram and connected as shown in the wiring diagram supplied with the dishwasher. The dispenser must operate on 230V/50 Hz with maximum power absorption of 15 W. Connect to the detergent dispenser outside the dishwasher using the red hose mentioned above. IMPORTANT: Whenever the type of detergent or rinse aid is changed, it is ABSOLUTELY ESSENTIAL to flush out the peristaltic pumps by placing the external intake pipes in water for a few cycles. Always use only products specifically recommended for use in a dishwasher. The internal pipes of the detergent and rinse paid pumps should be replaced by the After-Sales Service every 12 months or 15, 000 wash cycles. Failure to comply with this recommendation leads to forfeiture of the warranty entitlement on the appliance's water system. 9 6 SETTINGS SETTINGS During start-up, the functions/parameters listed below must be set or adjusted: A series of operations can be carried out when the dishwasher is first installed to customise it to the user's requirements. To perform these operations, access "programming mode" as explained below. 6. 1 Dishwasher parameter modification procedure: The two red digits provide the following information: Appliance off but powered up: all decimal points on both digits Appliance on: Boiler temperature Washing phase: Tank temperature Pause phase: Boiler temperature Rinse phase: Boiler temperature Programming phase: See parameter programming section Error message: See error messages section 6. 2 PARAMETER PROGRAMMING PROCEDURE To access the programming menu, proceed as follows: 1) switch the appliance off with the (OnOff) key key 7 times within 6 seconds. . Wait for the 6 seconds to pass; at the end P0 2) Press the appears on the display 3) Use the key to select the parameter for modification to display the parameter for modification 4) Press 5) Modify the parameter by pressing 6) Confirm the change by pressing 7) Select the other parameters for modification in the same way and proceed as described above 8) After setting all the appliance parameters, press the OnOff key to quit. The modification sequence only considers the parameters declared in the software to be modifiable (letter M in first column in table). If the problem persists after the dishwasher has been switched off and back on, proceed as described below: E. 1 E. 2 Boiler temperature probe malfunction Tank temperature probe malfunction Boiler temperature probe disconnected or not working Tank temperature probe disconnected or not working Water intake not completed in the maximum time allowed Check dynamic pressure in intake system, and inspect the water intake filter and rinsing nozzles for dirt. If the problem persists: - tank pressure switch has failed (continuous empty reading) - leak from pipe connected to air trap - drain siphon blocked - the tank is empty due to siphoning when the drain pump is not running Circuit board relay failure, check circuit board and inspect boiler heating element for damage Circuit board relay failure, check circuit board and inspect tank heating element for damage Inspect the filters for dirt and check that the drain hose is not blocked, bent or crushed. Check that the drain pump is not blocked by dirt by removing the insert on the sump (from inside the tank) If the problem persists: with tank empty: tank pressure switch has failed (continuous full reading) with tank full: drain pump failure -circuit board relay failure - tank heating element faulty or "furred" with limescale - tank temperature probe faulty or incorrectly positioned - water continues to enter the tank due to intake solenoid valve failure -circuit board relay failure - tank heating element faulty or "furred" with limescale - tank temperature probe faulty or incorrectly positioned - water continues to enter the tank due to intake solenoid valve failure Replace circuit board E. 3 Water intake malfunction E. 4 E. 5 Boiler overheating. Tank overheating E. 6 Water not pumped out of tank E. 7 Boiler heating malfunction (does not heat up) E. 8 Tank heating malfunction (does not heat up) E. 9 Microprocessor failure 13 8 INSTRUCTIONS FOR THE USER 8. 1 Control panel R 8. 8.

Do not use detergents intended for hand washing. We recommend the use of Smeg products, specially developed for this dishwasher. When topping up the tanks, take care not to swap the products; this might damage the dishwasher and cause malfunctions. Do not mix different detergents; this would damage the dispenser device. Industrial dishwasher detergents may cause serious irritations. Comply carefully with the instructions provided by the detergent producer on the pack. Turn on the mains water tap (user) The level of detergent and rinse aid in the containers. Check: That there is regenerating salt in the relative container (if fitted). That the filters are in place, the spray arms rotate, and there are no foreign bodies in the dishwasher. [. . . ] Clean away any limescale deposits to prevent excessive build-ups; If possible, leave the door ajar when not in use; Clean surfaces thoroughly and often with a damp cloth; use neutral, non-abrasive detergents which do not use chlorine compounds, which corrode and damage stainless steel. Do not use the products mentioned above even when cleaning the floor underneath or in the vicinity of the dishwasher, to ensure that fumes or drops cannot damage the steel surfaces. IMPORTANT: The dishwasher automatically performs program "P0" at the start of the day if water has been left in the tank and has dropped below the temperature of 40°C 9. 3 Periodic checks Remove the top and bottom spray arms by unscrewing the central screw and unscrew the caps from the ends of the rinsing arms as shown. Clean the holes and nozzles under a jet of clean running water; do not use tools which might cause damage. [. . . ]
