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 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). [. . . ] A short testing cycle can also be performed to verify operation of all the components. To perform these operations, access "programming mode" as explained below 6. 1 Dishwasher parameter modification procedure: (ONLY ACCESSIBLE AFTER FILLING IS COMPLETE or WITH THE DOOR OPEN) Indicator lights as follows: off; green; orange; flashing. on/off button for a few Access "programming mode" by pressing the seconds (UnLo 1:58 will appear on the display) with the appliance on (after the filling and heating phase); at the "beep", release the button and press it again quickly within 0. 5 seconds. Keep pressing the button again to scroll through all the modifiable parameters in the following order: Rinse aid delivery amount Detergent delivery amount Rinsing temperature Washing temperature Start-on/start-off. Set at "on" to start the cycle when the door is closed. Set at "off" for cycle start after confirmation with the start button Regeneration frequency, depending on water hardness (if softener is installed) tStP on/off "on" = minimum rinsing temperature as set, regardless of intake water temperature; the cycle duration may be a few seconds longer than the nominal length. "off" = the minimum rinsing temperature might be a few degrees lower than the setting if hot intake water is not used. 7 Detergent pump operating minutes display. Rinse aid pump operating minutes display. Display (also reset when needed) 6. 1. 8 Rinse aid pump To reset, press for 3 seconds. Display (also reset when needed) 6. 1. 9 Energy consumption ­ Display and reset To reset, press for 3 seconds. 6. 1. 10 Customisation of duration of program P4 The duration of program P4 can be customised from 5 to 20 minutes using the appliance parameter modification procedure, but the dishwasher must be set on program P4. After setting program P4 access the programming procedure and scroll through to "inF" (last parameter to button to modify the duration appear) then press the of the cycle (from 5 to 20 minutes) After a few seconds without the user pressing any buttons, the display will return to the normal operating status and the modifications will be saved. 6. 1. 11 Setting the Model (for After-Sales Service only) Modify by pressing . 10 6. 2 Starting the peristaltic pumps ­ rapid filling of detergent and rinse aid delivery circuit Perform after the parameter modification procedure explained in the previous point. Indicator lights as follows: off; green; orange; flashing. With the dishwasher powered up, access "programming mode" by pressing the on/off button for a few seconds; at the "beep", release the button and press it again quickly within 0. 5 seconds. The peristaltic pumps continue to operate until the same buttons are pressed again. The rinse aid and detergent symbol lights remain on as long as work is in progress; bear in mind that the rinse aid peristaltic pump fills the circuit in about 7 minutes, while for the detergent it only takes 2 minutes. 7 MALFUNCTIONS SHOWN ON THE DISPLAY The dishwasher is able to identify a number of malfunctions and show them on the display. If the problem persists after the dishwasher has been switched off and back on, proceed as described below: Err04 Tank temperature probe malfunction Tank temperature probe disconnected or not working Check dynamic pressure in intake system, inspect water intake filter and clean if necessary. Err05 Tank water filling malfunction If the problem persists: - tank pressure switch has failed (continuous empty reading) - leak from pipe connected to air trap - valve vent exhaust pipe blocked Inspect the filters for dirt and 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 the tank empty: tank pressure switch defect (the contact is locked on full) with tank full: drain pump has failed - with tank full: see above (water pump-out malfunction) - with tank empty: safety pressure defect (the contact is locked on full) -circuit board relay failure, - contactor failure. - boiler safety thermostat failure, - boiler temperature probe faulty or incorrectly positioned - water continues to enter the tank due to tank pressure switch defect boiler temperature probe disconnected or not working Check that the water intake tap is on and the dynamic pressure in the intake system, inspect the water intake filter and clean if necessary. If the problem persists: - boiler pressure switch has failed (continuous empty Err06 Water pump-out malfunction Err09 Tank water level too high Err23 Boiler heating malfunction (does not heat up) Err24 Boiler temperature probe malfunction Err25 Boiler water filling malfunction 11 reading) - pipe leaking/disconnected Err26 Err27 Err28 Boiler emptying malfunction Boiler emptying malfunction ­ with tank full Boiler heating malfunction (overheating) - check that rinsing spray arm nozzles are clean - boiler pressure switch has failed (continuous full reading) - rinsing pump not working Boiler pressure switch has failed (continuous full reading) -circuit board relay failure, or - contactor failure 8 INSTRUCTIONS FOR THE USER 8. 1 Control panel On-off button Program selection button Start CONFIRM/PAUSE button Total emptying button (tank and boiler) Additional function selection button L1 Main power on light L2 Intake/standby cycle in progress light (orange/green) L3 Pump-out in progress light No rinse-aid symbol (if a system for monitoring outside the dishwasher is provided) Tank heating element on symbol No salt symbol (if softener is fitted) Boiler element on symbol No detergent symbol (if a system for monitoring outside the dishwasher is provided) 12 8. 2 Before washing Use only detergents and rinse aids for industrial dishwashers. 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. [. . . ] 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 11. 2 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. Reassemble the spray arms with care. Clean the outside of the appliance with a damp cloth and neutral soap, rinsing and drying thoroughly. 11. 3 Lengthy periods out of use If the dishwasher is to be out of use for a fairly long period of time, the detergent and rinse aid dispenser devices must be emptied to prevent crystallisation and damage to the pumps: Remove the intake hoses from the detergent and rinse aid containers and place them in a container of clean water, then perform a few wash cycles followed by a complete pump-out. Finally, turn off the master switch, close the water intake valve and leave the door ajar until the interior is completely dry. [. . . ]
