Indicator lights showing: off; green; orange; flashing. Caution: the tank and boiler temperatures shown on the display may be differ from the actual temperatures by a few degrees, especially in transient phases (just after the FILL is completed, just after the end of the cycle, etc. ) due to the inertia of the measurement probe. 6. 3 Rinsing temperature setup Modify the value of the parameter by pressing . 85°C 6. 4 Washing temperature setup Modify the value of the parameter by pressing . 62°C Indicator lights showing: off; green; orange; flashing. 6. 5 Rinse aid dispensing setup Modify the value of the parameter by pressing . 17 RINSE AID Delivery time (s) Delivery quantity (c. c. ) CWH 520 0 6 * default value (factory preset) 12 18 24 30* 36 42 0, 0 0, 7 1, 3 2, 0 2, 7 3, 3 4, 0 4, 7 6. 6 Detergent dispensing setup DETERGENT Modify the value of the Delivery time Delivery parameter by pressing (s) quantity (c. c. ) . 0 0, 0 4 * default value (factory preset) 8 12* 16 20 24 30 36 42 1, 7 3, 3 5, 0 6, 7 8, 3 10, 0 11, 7 13, 3 15, 0 6. 7 Autostart function Modify the parameter (ON/OFF) by pressing . Set at "on" to start the cycle when the door is closed. If the problem persists after the dishwasher has been switched off and back on, proceed as described below: The antiflooding system has been Err01 activated (for the relevant models only). Err04 Tank temperature probe malfunction Large water leak: check the origin of the problem. Tank temperature probe disconnected or not working. The tank does not fill within the allowed time: check water intake tap, dynamic pressure in intake system, cleaning of water intake filter, possible damage to 21 Err05 Tank water filling malfunction CWH 520 water intake hose or cleaning of rinsing nozzles. If the problem persists during FILL: tank pressure switch has failed (continuous empty reading: check whether tank safety pressure switch is tripped) leak from pipe connected to air trap If the problem occurs during work cycle filler hose bleeder valve fouled: tank empties completely at end of a wash cycle due to siphon effect. Water pumpout malfunction 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" signal: tank pressure switch faulty or leak from connections of air trap connection pipe (water entering pipe) with tank full: drain pump failure With tank full: see above (water pumpout malfunction) With tank empty: constant "tank full" signal: safety pressure switch faulty or leak from connections of air trap connection pipe (water entering pipe) The problem might occur because water is continually entering the tank (the causes are as for Err5 ­ see above) If it persists, check in this order: damaged boiler heating element contactor failure, boiler safety thermostat failure, 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 the pressure switch is indicating full even with the boiler empty: check and if necessary replace the boiler air trap and/or the relative pressure switch: the problem is generally preceded by "boiler overheating E28" boiler temperature probe disconnected or not working 22 Err06 Err09 Too much water in tank Err23 Boiler does not heat up as expected Err24 Boiler temperature probe malfunction CWH 520 Err25 Boiler water filling malfunction 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) 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 Err26 Boiler emptying malfunction Err27 Boiler emptying malfunction ­ with Boiler pressure switch has failed (continuous full tank full reading) First check: boiler pressure switch has failed (continuous full reading) pipe leaking/disconnected: water entering pipe malfunction connected to air trap, pressure switch continues to give full reading even with boiler empty, heating element operating dry Or: circuit board relay failure, or contactor failure Err28 Boiler heating (overheating) 23 CWH 520 8 INSTRUCTIONS FOR THE USER 8. 1 Control panel Onoff button Program selection button Start CONFIRM/PAUSE button Total emptying button (tank and boiler) Additional function selection button L1 Mains power on light L2 Intake/standby cycle in progress light (red/green) L3 Pumpout in progress light No rinseaid symbol (if a system for monitoring outside the dishwasher is provided) Tank heating element on symbol No salt symbol (if softener is fitted) Boiler element on symbol No detergent symbol (if a system for monitoring outside the dishwasher is provided) 24 CWH 520 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. [. . . ] If the problem persists, contact the aftersales service. Check that the dishwasher drain hose and rain are unobstructed and the drain is not too high up; see connection diagram. Check that the dishwasher hose and drain are unobstructed and the drain is not too high up; see connection diagram. INADEQUATE RINSING Rinse aid unsuitable or not being delivered correctly. [. . . ]
