VERIFICATION OF ALARM CONDITIONS In order to facilitate the identification of a fault, the CONDITIONS shown on the display panel, which cause one of the safety systems to intervene, are listed below together with the possible CAUSES which will simplify the identification and elimination of the fault condition. N.B. : - The control board is unlikely to develop a fault, and should therefore be examined as a last resort. N.B. In all the situations listed above, the DW remains inoperative and no functions can be performed. 26 CONDITION INTERVENTION CAUSE LEDs - Off POWER FAILURE 1. Restore the power supply 2. ON/OFF switch faulty 3.
Wiring between switch and board damaged/disconnected LED [ L 1 ] LEDs - Off WATER FILL Maximum time 5 min 1. Tap closed 2. Mains pressure LED [ L 2 ] LEDs - Off WATER REPLENISHMENT Maximum time 90 sec (total time) 1. Pressure switch on "EMPTY" (1-2) 2. Leakage from sump / couplings 3. Pressure drop on pressure switch connection 4. Water distribution in IWMS not correct 5. Dishes upside down 6. Sump filter blocked 7. Intervention of Anti-flooding device LED [ L 2 ] LEDs - Off PRESSURE SWITCH "EMPTY" Washing & heating maximum time 2 min. x 3 1. Pressure switch on "EMPTY" (1-2) 2. Leakage from sump / couplings 3. Pressure drop on pressure switch connection 4. Dishes upside down 5.
Sump filter blocked 6. Cavitation of washing pump LED [ L 3 ] LEDs - Off TEMPERATURE SENSOR (Range:- 5300 - 209.200 Ω) Instantaneous intervention 1. Temperature sensor open/short-circuited 2. Temp. sensor out of limits/incorrectly calibrated 3. Water temperature >80°C 4. Sensor connections false/detached 5. Water temperature LED [ L 4 ] LEDs - Off WATER HEATING Maximum time 45 min 1. Heating element damaged 2. Heating element connection damaged/detached 3. Safety thermostat open/disconnected 4. Poor thermal contact on temperature sensor 5. Conducting paste insufficient / absent 6.
Circular filter blocked LED [ L 5 ] LEDs - Off PRESSURE SWITCH "EMPTY" Water drain not carried out or not completed Instantaneous intervention 1. Pressure switch on "FULL" (1-3) 2. Drain system unsuitable (hose, siphon etc.) 3. Cavitation of drain pump impeller 4. Pump not fitted correctly in its seat 5. Drain pump cut-in tube blocked/kinked 6. Float valve in resin tank open 7. Water in IWMS level chamber LED [ L 1 ] LED [ L 2 ] LEDs - Off MOTOR BLOCKED Washing / Drain Instantaneous intervention 1. Rotor blocked (seized, foreign bodies) 2. Friction on pump impellers; impellers stripped 3. Electrical interruption of motor 4. Start-up capacitor short-circuited/damaged 5.
Motor connection damaged/detached
