[. . . ] 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. 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. 6 CWC 611 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 professional dishwasher. Failure to comply with this recommendation leads to forfeiture of the warranty entitlement on the appliance’s water system. The internal pipes of the detergent and rinse aid peristaltic pumps should be replaced by the AfterSales Service every 12 months or 15, 000 wash cycles. 5. 1 Using the water softener (on models with this feature only) The quantity of lime in the water (which indicates its hardness) causes whitish marks on dry dishes and dishes also tend to lose their shine over time. The dishwasher is equipped with an automatic water softener which removes the substances that cause hardness from the water with the aid of regenerating salt. The first time the dishwasher is used, a litre of water must be poured into the tank with the salt. Whenever the tank is filled, always take care to ensure that the cap is firmly closed. The mixture of water and detergent must not get into the salt tank, as this would impair operation of the regeneration system. The problem might occur because water is continually entering the tank (the causes are as for “Er 05” – see above) If the boiler heating element is damaged, this might be due to operation with no water in the boiler - the pressure switch is indicating full even with the boiler empty: - damaged boiler heating element – conta ctor failure - open on boiler safety thermostat side. boiler temperature probe faulty or incorrectly positioned - motherboard relay failure, Important: If the boiler heating element is damaged, this might be due to operation with no water in the boiler, pressure switch continues to give full reading even with boiler empty: check boiler air trap and/or relative pressure switch and replace if necessary. Boiler temperature probe disconnected or not working The boiler does not fill within the allowed time: check water intake tap, dynamic pressure in intake system, cleaning of water intake filter, possible damage to water intake hose or check, in this order: - boiler pressure switch has failed (continuous empty reading). - pipe leaking/disconnected (water entering pipe) – item “rp” in service menu not set correctly - check that rinsing spray arm nozzles are clean - boiler pressure switch has failed (continuous full reading) - pipe leaking/disconnected (water entering pipe) - rinsing pump not working Boiler pressure switch has failed (continuous full reading) if appears when rinsing pump is not present; presence of boiler pressure switch: check setting of item “rp” in service menu “rp”=on for models with rinsing pump “rp”=of for models without rinsing pump Er 04 Er 05 Water pump-out malfunction Er 06 Boiler does not heat up as expected.

Pressed for 5” 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. 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. [. . . ] 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. 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 pump -out. 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). 18 CWC 611 10 TROUBLESHOOTING How to deal with any problems without calling the after-sales service PROBLEM Led 6 does not light up Washing program does not start Poor washing results POSSIBLE CAUSE Mains power failure The dishwasher has not yet finished filling.
