[. . . ] 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. Installing the drain hose to a siphon with valve, the maximum height of the drain outlet is reduced to 600 mm. 5 CWC 611 4. 2 Electrical connection For models with a water softener an ‘approved’ double check valve or some other no less effective device providing backflow prevention protection to at least fluid category two shall be fitted at the point of connection between the water supply and the fitting or appliance. For models without a water softener an ‘approved’ single check valve or some other no less effective device providing backflow prevention protection to at least fluid category two shall be fitted at the point of connection between the water supply and the fitting or appliance. 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. 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. - Leak from pipe connected to air trap: if problem persists, check during working programme. Drain line vent valve fouled: tank empties completely at end of a wash programme due to siphon effect. Inspect the filters dirt 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 persist: With the tank empty: tank pressure switch defect (the contact is locked on full) 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 – 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.
