Smegs products are simply built to fail
I have a Smeg DI612CA1 dishwasher and doing some routine cleaning of it one day the plastic clips that hold the upper spray arm just broke. I was confused at first when putting it back together because I hadnt even realised it had broken, the tiny plastic nubs holding it in place just fell off.
After ordering a replacement part (had to get a whole new spray arm because the small nut that had beoken wasnt abailable seperately) and installing it, I then realised that in the process of reinstalling it another plastic clip attached nearby also disintegrated so I had to buy ANOTHER replacement part for another bit.
That new replacement part arrived today, new in plastic and guess what, the same damn tiny plastic clip had already broken in transit!
These bits of plastic are mere milimeters thick, exposed to high heats, changing temperatures, and constant vibration. There is simply no way someone designed this without knowing that they would fail within a handful of years
