Relatively new dishwasher, just off guarantee (of course!), stopped working. The error code says "something amiss with the outflow". Troubleshooting pages at hand I look at the filters (clean), the pump (seems OK but barely accessible, so…) and the runoff hose (not bent, perhaps clogged?).
Should I call in some guy or try to tackle things myself? To get an idea of the difficulty I head to YT and watch a dude working on a similar model. Filters, pump, hose, yadda, yadda. But wait! What is he doing there? He scrubs a discreet little thingy near the pump. What is that? A bloody sensor!
Sacrificing my current toothbrush I did the same and… it works again.
Now what really pissed me off is that this sensor and its cleaning aren't mentioned anywhere in the user manual (I even downloaded a PDF version to check).
