[. . . ] Drainage: The dishwasher is fitted with a drain pump and can operate with drain connections on the floor or wall. Refer to the connection diagram for the maximum permitted height of wall drains – (see TECHNICAL DATA) Warning: make sure that the intake and drain hoses are not bent, constricted or crushed after installation. When installing the drain hose to a siphon with valve, the maximum height of the drain outlet is reduced to 600 mm. 4. 2 Electrical connection The dishwasher and any additional equipment must be connected to the electrical system by authorised, skilled staff, in accordance with the relevant regulations; also comply with the technical instructions for the connection. 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. 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. 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 it persists, check in this order: with tank empty: constant “tank full” reading: tank pressure switch faulty or leak from connections of air trap connection pipe (water entering pipe) - with tank full: drain pump has failed 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 - contactor 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.

Switch off and back on to allow reuse. 8. 2 Before washing Use only detergents and rinse aids for industrial dishwashers. 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. [. . . ] Remove any salt residues around the opening before screwing the cap back on. 17 SMEG 9 CWG411MDA MAINTENANCE AND CLEANING Although no particular scheduled maintenance is required, users are advised to have the dishwasher checked by a specialist technician twice a year. N. B. : the manufacturer accepts no liability for wilful damage or damage deriving from carelessness, neglect, failure to comply with instructions, regulations and standards or incorrect connections, which lead to forfeiture of warranty cover. If possible, leave the door ajar when not in use; Clean surfaces thoroughly and often with a damp cloth; use neutral, nonabrasive 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, as vapours or drops may damage the steel surfaces. [. . . ]
