[. . . ] Connect to the detergent dispenser outside the warewasher using the red hose mentioned above. 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 warewasher. Failure to comply with this recommendation leads to forfeiture of the warranty entitlement on the appliance's water system. 12 NWC 611 5 SET-UP Setup During first startup, the functions/parameters listed below must be set or adjusted: A series of operations can be carried out when the warewasher is first installed to customise it to the user's requirements. To modify the parameters, proceed as follows. 5. 1 Display Contents The two green digits provide the following information: Appliance off but powered up: all decimal points on both digits Appliance on: Boiler temperature Washing phase: Tank temperature Pause phase: Boiler temperature Rinse phase: Boiler temperature Programming phase: See parameter programming section Error message: See error messages section 5. 2 Note on display of temperatures Both the Boiler and the Tank temperatures provide instantaneous readings of the current value picked up by the probe, but due to the thermal inertia of the probe or its seat, wait about 1 minute after the heating element power absorption reading to obtain the real temperature. 5. 3 Parameter programming procedure To access the programming menu, proceed as follows: 1) switch the appliance off with the (On Off) key 2) Within 6 seconds, press key P1 (SHORT wash) 7 times. Wait for the 6 seconds to pass; at the end P0 appears on the display 3) Use key P1 to select the parameter to be modified 4) Press the PUMPOUT KEY to display the parameter for modification 5) Modify the parameter by pressing key P1 6) Confirm the change by pressing the PUMPOUT key 7) Select the other parameters for modification in the same way and proceed as described above 8) After setting all the appliance parameters, press the On Off key to quit. 13 5. 4 Modifiable parameters NWC 611 This table lists the model choice or cycle and temperature option parameters.

(on some models only ) Adjustments are made using the adjuster screw AS SHOWN. The quantity dispensed is reduced by turning anticlockwise and increased by turning clockwise. RB: Rinse aid dispensing regulator screw Adjustments are made using the adjuster screw AS SHOWN. The quantity dispensed is reduced by turning clockwise and increased by turning anticlockwise. It is recommended that periodic monitoring of detergent and rinse aid dispensing; every 15. 000 cycles suggested replace the inner peristaltic pipe 15 NWC 611 1 MALFUNCTIONS SHOWN ON THE DISPLAY (FOR THE TECHNICIAN) The warewasher is able to identify a number of malfunctions and show them on the display. If the problem persists after the warewasher has been switched off and back on, proceed as described below: E. 1 Boiler temperature probe malfunction Tank temperature probe malfunction Water intake malfunction Boiler temperature probe disconnected or not working Tank temperature probe disconnected or not working Water intake not completed in the maximum time allowed Check dynamic pressure in intake system, clean water intake filter. If the problem persists: tank pressure switch has failed (continuous empty reading) leak from pipe connected to air trap drain siphon blocked the tank is empty due to siphoning when the drain pump is not running Reduce boiler temperature to 80° Circuit board relay failed, check circuit board and inspect boiler heating element for damage Reduce boiler temperature to 58° Circuit board relay 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 tank empty: tank pressure switch has failed (continuous full reading) with tank full: drain pump failure circuit board relay failure boiler heating element faulty or "furred" with limescale boiler temperature probe faulty or incorrectly positioned E. 2 E. 3 E. 4 Boiler overheating. E. 5 Tank overheating E. 6 Water not pumped out of tank E. 7 Boiler heating malfunction (does not heat up) 16 E. 8 Tank heating malfunction (does not heat up) E. 9 Microprocessor failure NWC 611 circuit board relay failure tank heating element faulty or "furred" with limescale. [. . . ] Remove spray arms and clean them (8. 2 Periodic checks) See "Cleaning the filter during the day" Check type and quantity of detergent. Check that the intake filter is not fouled. If you are unable to solve the problem, call the aftersales service. Check temperature shown on the display, call the aftersales service if less than 50°C Increase wash cycle duration, especially if dirt has dried on. [. . . ]
