Tests to be performed: YES YES Check and if necessary replace the wiring and restart the diagnostic cycle to check for further alarm conditions. 2007-10 SOI/DT-mdm FCPD-dp Quality-fz 24/59 599 70 32-47 E23 E23: Malfunction of the component (triac) that controls the drain pump E23 Is the resistance of the pump about 150-200 Ω? (measure across connectors J7-1 and J7-9 on circuit board side - fig.4- Is the resistance of the pump about 150-200 Ω? (measure directly on the pump) -see fig.5- Replace the pump and restart the diagnostic cycle to check for further alarm conditions. NO I NO Measure across connectors J7-1 / J7-9 and the structure of the appliance - fig.6 - Is there current leakage?
NO Replace the main circuit board and restart the diagnostic cycle to check for further alarm conditions. YES Check and if necessary replace the wiring and restart the diagnostic cycle to check for further alarm conditions.
