(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 17 NW511 5. 7 Adjusting the regeneration frequency (models with softener only) 5. 8 Memorisation procedure To access the programming menu, proceed as follows: 1) switch the appliance off by pressing the On Off key 2) Hold down the and keys simultaneously for 6 seconds; H0 appears on the display 3) Use the key to modify the parameter; H0, H1, H2, H3, H4, H5 and H0 will appear on the display in cyclic sequence 4) Press the On Off key to confirm the change and quit programming mode. With values over 60°dF an external water treatment device must be used and the regeneration frequency must be set at H00 5. 9 Table of parameters This table shows the relationship between the intake water hardness and the quantity the resins are able to treat; regeneration is required once the appliance has performed the set number of cycles. Regeneration cycle duration: 12 minutes.

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 also controls: if tank and boiler pressure switch properly if the rubber pipes are connected correctly if the air trap is clogged/dirty if the rinse pump running correctly E. 4 Boiler overheating. Reduce boiler temperature < 80°. Circuit board relay failed, check circuit board and inspect boiler heating element for damage Reduce boiler temperature < 58°. Circuit board relay failed, check circuit board and inspect tank heating element for damage E. 2 E. 3 E. 5 Tank overheating 19 E. 6 NW511 Water not pumped out of tank 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 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 warewasher with a basin and disconnect it from the electrical mains. Unscrew the screw A, release the tang B and lift it. Check that the impeller of the drain pump underneath the cover turns freely, and is free from dirt, limescale residues, or pieces of glass. [. . . ] POOR WASHING RESULTS Inappropriate cycle set Dynamic pressure of mains water insufficient Spray arm nozzles fouled Limescale in boiler INADEQUATE RINSING 28 PROBLEM STAINS ON GLASSES AND CUTLERY NW511 POSSIBLE CAUSE Rinse aid unsuitable or not being delivered correctly. Water hardness above 12°dF or large amounts of dissolved salts Drain hose incorrectly positioned or partially obstructed. Low rinsing temperature due to thermostop OFF POSSIBLE REMEDY Check container of rinse aid and whether it is suitable for the type of mains water. If the problem persists, contact the aftersales service. [. . . ]
