As part of the renewal of our defective dishwasher, we have replaced the sink. The first sink was from Franke. However, the mounting on the countertop was an ordeal. The mounting brackets of 1 sink (10 years ago) had to screw on the bottom and it was perfect. This time it's plastic tabs inside open like dowels, which are pressed and thereafter with a plastic pin, which has to be taken there, arritiert the brackets. Unfortunately, this could not be completely submerged at all, she sprung back repeatedly. When tightening the clamps it pulled the whole device again from the plate. We have spent hours. In the end we cut from a hook of the same diameter as the plastic bolts, new bolts of metal, smashed them, then finally stopped the device. Here the company Franke has clearly saved in the wrong place !! Otherwise the sink looks very good.
