Main Switch,

About This Part

Is your dishwasher refusing to respond when you turn the dial? A faulty main switch could be why your AEG appliance has stopped working properly. Over time, the control knob experiences wear and tear from constant use, eventually failing to engage the internal mechanism that powers your machine. This genuine replacement main switch (OEM reference 140005730027) restores full functionality to your dishwasher's control system. It's a straightforward component to replace, rated as difficulty level 2, making it an ideal DIY repair for most homeowners. Before you start, locate your dishwasher's E-Nr model number—you'll find it on the rating plate inside the door edge. Take a photo of this number before ordering to ensure complete compatibility with your specific AEG model. Installation typically involves removing the outer casing panel and disconnecting the old switch from its wiring harness. The new switch simply clips into place and reconnects using the same terminals. Most people complete the job in under thirty minutes with just basic tools. Please verify your E-Nr model number matches this part's compatibility before purchasing.
