Re: Siemens iQ100, unscrewed wrong part – help!
That’s the Aqua Sensor then that you’ve force twisted it and it’s fallen into the base tray. The photo you gave shows it before it fell, correct?
The iQ100 covers a number of variants so the full ENr number (etched into the top of the stainless door panel) will be required to know how best to access it. But yes on those beasts access ain’t the greatest. Time to drag the machine out and remove the RH side panel.
To access the pump the front bottom plinth needs to come off.
