2.4 Power Supply Connection Conversion Possibilities These machines are supplied as standard for connection to 3 AC 208V 60Hz. Connection to one or two phases is possible but this results in a heating power reduction; see C Table 2. If a heater rating of 6kW is to be achieved with connection to a single phase, then the connection of the heater elements and power supply should be modified in accordance with the following diagram. x Fig. 3:Heating Connection (6kW) with 208VAC Warning! Connection of the phase terminals isonlypermitted when in accordance with 080 Fig. 3. For details, see Heater Element Connection Conversion From 3 N AC 400 V To 230VAC, 080 4.1. 2.5 Heater Control, Heater Relays Both heater relays, solenoid voltage 6VDC, are positioned together with the overflow level switch on a mounting bracket on the connecting strip, 010 Fig. 8, Pos. B. In cleaning stages both relays are operated but the second one is switched on approximately 100 milliseconds after the first. In the drying phase relay 1K1/1 only is operated with pulsed power. The neutral conductor of the star connection is also laid via this relay. For heating water the relays are only switched on after the heating level switch, 050 2.6.2 Heater Level Switch B1/10, has remained switched on for 2 seconds without a break.

3 Fault Repair 3.1 No Voltage for Relay Solenoid 1K1/3 in Drying Unit (TA) G 7882 CD, G 7883 CD Cause No voltage between contacts 3 (TA on) and 1 (N) of plug 12 on ELZ 081 electronic. Remedy ADisconnect plug 12 and check output 16 via the service mode, 070 2.9.4S 24, Checking Outputs 12 - 19. AIf no voltage is present, check the voltage supply for EZL 081 via main switch S2 and door contact switch 1S4 at plug 13, contact 3 (L1) and 4 (N). AIf voltage is present, replace the electronic; see Electronic Module EZL 081 Removal, 070 4.5. 3.2 Suds Warm Up Too Slowly/Wash Cycles Take Longer to Heat Water Cause Heater element defective. Remedy ACheck the heater elements for continuity; see Checking the Heater Element, 030 4.1. AReplace the faulty heater element; see Heater Element Replacement, 030 4.5. Cause Heater relay 2K1/1 or 1K1/1 do not switch. Remedy ACheck solenoid voltage (6VDC). ACheck plug connections. ACheck solenoid for continuity. ACheck contacts for continuity.

3.3 Load Does Not Dry Cause Heater relay 1K1/1 does not switch. Remedy ASee also Suds Warm Up Too Slowly/Wash Cycles Take Longer to Heat Water, 080 3.2. Cause Heater element R1 defective. Remedy ACheck heater element R1 for continuity; see Checking the Heater Element, 030 4.1. AIf necessary, replace the heater element; see Heater Element Replacement, 030 4.5.
