Electrolux EFS - Dishwashing Systems Platform Electrolux Professional Electronic Dishwasher SERVICE MANUAL 9. SPECIAL FEATURES 9.1 RESIN REGENERATION CYCLE TANK BOILER The regeneration cycle is activated by pressing the button shown in the figure, for at least 5 seconds. For this key to be enabled parameter rE (in family CFG) must be set to 1. At this point you can enter the number of wash cycles that can be performed after each regeneration: parameter rCY in the counters family Cnt. If rCY is set to zero the counter is disabled, otherwise after the preset number of cycles the message rEG is displayed to confirm that regeneration is possible (this is an information-only message with no effect on operation of the appliance, so you can continue to use the dishwasher). The message is cleared when the regeneration cycle is terminated. The number of regeneration cycles performed can be checked by consulting the parameter nrE in the Cnt family of counters. When there are just 15 cycles remaining before the next regeneration cycle, at the end of the wash cycle the display shows the message End followed by 15, at the end of the next wash cycle the display shows End and 14, and so forth, i.e. the display informs the user of the number of wash cycles still available before resin regeneration is required. Before starting the regeneration cycle remove the siphon spillway. CAUTION: if the regeneration cycle is accidentally started, it can be switched off by pressing the button shown in the figure, for at least 5 seconds. The hardness of the water exiting the softener can vary between 3°fH - 10 °fH / 1.7 °dH - 5.6 °dH / 2.1 °cH - 7 °cH. 9.2 MEDICAL LINE DISHWASHER WITH DOOR/HOOD LOCK DEVICE The medical line dishwasher with door/hood lock device has a device that prevents door/hood opening for the entire duration of the work cycle. For the door/hood lock to be active, the parameter tYP (in the CFG family) must be set to 3. The dishwasher door/hood is locked at the start of a wash cycle and is released at the end of the final pause after rinse. The wash compartment can be accessed by stopping the work cycle in progress, as the locking device is thus disabled. A pause at the end of rinse can be set by means of the parameter rPA (in thedPA family). This parameter is common to all 3 wash cycles. The rinse water temperature is displayed during this pause. Another final pause in the cycle can be set by setting the parameters FP1, FP2, FP3. During the final pause the display shows the time remaining for completion of the cycle. The door/hood lock device will be deactivated at the end of the final pause (FP1, FP2, FP3). For correct performance of the wash cycle the pause at the end of rinse and the final pause must assume the default values (see Prog 032 - 034 - 035). 9.3 DETERGENT AND RINSE AID LEVEL SENSORS ACTIVATION By setting the parameter LES (in the CFG family) to 1, management of the level sensors located inside the external detergent and rinse aid tanks is enabled. During the rinse phase, when the rinse aid inside the tank has finished, the message rAi 0 appears on the display. When the detergent inside the tank is finished, the message dEt 0 is displayed and after a number of wash cycles equal to CdE (in the dPA family) the dishwasher inhibits the activation of other wash cycles. Therefore the detergent level in the tank must be restored. DOC. NO. 5956.446.06 ©Copyright 2005 by Electrolux Professional P.17/88
