備用水箱（含塞孔）

Had to swap out my old tank and this spare fits perfectly into the 304000 model, no leaking at all with the bung secured. It's nice having a backup that matches exactly what came with the appliance.

Filled it right up to the brim and the bung held fast with no leaks at all. The molded shape snapped perfectly into place inside my machine.

The bung seals tightly without any fuss, and it slots into the 304000 model exactly where it should. I’ve had no leaks since swapping it in, and the whole unit feels solid for the price.
