[. . . ] The total rated power is stated on the appliance's technical data plate. The electrical protection devices fitted for the dishwasher must serve this appliance only. The user must have a master switch and a differential safety breaker, with rating suitable for the appliance's characteristics, installed on the electricity supply line in accordance with the relevant regulations. These switches must be installed close to the dishwasher, be easily accessible after installation, and provide complete disconnection from the electrical mains in overvoltage class III conditions. The dishwasher is always powered up unless the master switch is turned off. The terminal for the connection is in the bottom righthand corner of the appliance. The earth wire (PE) is yellowgreen in colour, the neutral wire (N) is blue and the live wires (L1, L2, L3) are black, grey and brown. In the event of singlephase connection (230V1N~), the connection to the electrical mains must be made using a cable with plug compliant with the relevant regulations. THE POWER SUPPLY CABLE MUST BE REPLACED BY THE MANUFACTURER OR AN AUTHORISED SERVICE CENTRE TO PREVENT ALL RISKS. 10 CWG410 Key to electrical system diagram Boiler temperature probe Tank temperature probe Detergent sensor Rinse aid sensor Filter sensor Flowmeter Salt sensor Door sensor Rinsing pump Washing pump Boiler level pressure switch Boiler safety thermostat Terminal board RFI filter Mains fuse Boiler contactor Boiler heating element Overtemperature fuse Tank safety thermostat Tank heating element EVA EVR EVS PB PD EVF PS PLA PLV PSV AQS SB SI TM TV TF TPL TPR TRV TB Aquastop solenoid valve Regeneration solenoid valve Brine discharge solenoid valve Rinse aid peristaltic pump Detergent peristaltic pump Filler solenoid valve Drain pump Analog level pressure switch Tank level pressure switch Tank safety pressure switch Aquastop microswitch Motherboard Interface board Terminal board ground Tank ground RFI filter ground Washing pump ground Rinsing pump ground Tank heating element ground Boiler heating element ground NTCB NTCV SDET SBRIL SFIL FLMT SS RD PR PL PLB THB M LF FUSE CB RB TFU THRV RV 11 CWG410 Figure 1 ­ Appliance electrical system diagram 12 CWG410 5 FIRST START-UP First startup The electrical protection system must undergo a functional test before the appliance is put into operation. Always use only products specifically recommended for use in a dishwasher. If the problem persists, the circuit board relay has failed: check circuit board and inspect boiler heating element for damage Reduce tank temperature to 58°. If the problem persists, the circuit board relay has failed: 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 the tank empty: tank pressure switch defect (the contact is locked on full) with tank full: drain pump has failed If the system fails to pump out because the drain pump is fouled (as a result of incorrect filter positioning), proceed as follows: Bale out the dishwasher with a basin and disconnect it from the electrical mains. Check that the impeller of the drain pump underneath the cover turns freely, and is free from dirt, limescale residues, or pieces of glass. circuit board relay failure boiler heating element faulty or "furred" with limescale boiler temperature probe faulty or incorrectly positioned circuit board relay failure tank heating element faulty or "furred" with E. 4 Boiler overheating.

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. Failure to comply with this recommendation leads to forfeiture of the warranty entitlement on the appliance's water system. Comply carefully with the instructions provided by the detergent producer on the pack. [. . . ] TOP SPRAY ARMS BOTTOM SPRAY ARMS 1 1 2 3 1 Clean the outside of the appliance with a damp cloth and neutral soap, rinsing and drying thoroughly. 9. 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 pumpout. Finally, turn off the master switch, close the water intake valve and leave the door ajar until the interior is completely dry. The detergent and rinse aid intake hoses must be put back into the containers when the dishwasher is returned to service, taking care not to swap them over (red hose = detergent, blue hose = rinse aid).
