My smeg dishwasher stopped working so I took the side panels off and the bottom was full of water. I drained the water and ran a cycle and found a leak through an o-ring just before what looks like a filter, so I assume the filter is blocked. Do I need to take the bottom off the dishwasher to get the filter out? It is a DWI612C dishwasher.
