Hello, I ordered two deep fryers in a short time for myself and my father-in-law. With both of them, you can take out the whole housing to wash it. The whole oil container. Underneath you can then see the heating coils.....Only I have to note that it may still not work with certain series...Why ? I, for example, have a Schuko plug that is common in Germany, but my father-in-law's deep fryer has a Swiss plug...both bought here at Galaxus! Why this is the case is beyond me....I hope I could help...
