Electrolux EFS - Dishwashing Systems Platform Electrolux Professional Electronic Dishwasher SERVICE MANUAL AL_5 AL_6 AL_7 AL_8 AL_9 AL_10 AL_11 AL_12 AL_13 (Polarity/motor rotation direction inverted?!). Appears if the bottom limit switch (S3) cuts in during lifting. On installation this alarm can occur due to incorrect sequence of the phases: invert the two phases on the power supply terminal board. TIMEOUT- The time taken for hood lifting was more than the time fixed by parameter t_2 : a) check that the motor works. TIMEOUT- The time taken for lifting was more than the time fixed by parameter t 2. Check correct operation of the: a) motor (thermal protection N7); b) top limit switch (S5 and S5'). The hood is open but the bottom limit switch (FC_DW) has cut in. Appears with hood fully open, if: - the limit switch (S5) returns to the rest position; - the bottom limit switch (S3) cuts in; - S3'' cuts in. Appears if with hood fully open the "door closed" microswitch cuts in. Appears if with hood fully open the "door closed" microswitch cuts in. - S5 could be disconnected. During lowering, the top limit switch (FC_UP) has not returned to the rest position. The limit switch must return to the rest position within a time given by parameter t_6: a) check that the motor works; b) (Polarity/motor rotation direction inverted?!). b 3 During the initial lowering phase the top limit switch (S5) must return to the rest position within a time given by the parameter t_6 otherwise the alarm b 3 appears. - S5 could be stuck. - S3' could be disconnected. On installation, this alarm can occur due to incorrect sequence of the phases: invert the two phases on the power supply terminal board. - Appears if the bottom limit switch S3 cuts in before S3" during lowering. Appears if the top limit switch (FC_UP) cuts in during lowering. (Polarity/motor rotation direction inverted?!). b 3 Appears if the top limit switch (S5) cuts in during lowering. On installation, this alarm can occur due to incorrect sequence of the phases: invert the two phases on the power supply terminal board. TIMEOUT- The time taken for hood closing was more than the time fixed by parameter t_2 : a) check that the motor works. - - TIMEOUT- The time taken for lowering was more than the time fixed by parameter t_2. - S3' could be disconnected. Appears during hood lowering if, after S3'' cuts in, the bottom limit switch S3 does not cut in within the time fixed by parameter t 3. The two hand safety contacts K and K' must be both closed or both open. If this does not occur the alarm appears. - One of the two relays (K or K') could be stuck or disconnected.
