We have had our SMEG DWI710e for over 8 years now and it has been outstanding
the thermostat has cut off a few times but this is easily reset by anyone with a bit of diy ability, I am just in the process of replacing a couple of bits (front panel fascia and on/off switch) but this is just due to wear and tear I would certainly recommend one

I have rated service and support low as I have never used them

We bought our Smeg dishwasher nearly 2 years ago, the first time it broke down, fortunately it was still under warrenty. Unfortunately, the service team tried their utmost to prolong the agony of not having a dishwasher as long as possible. 3 different "engineers" (or guys with a bag of tools, a van and no knowledge of dishwashers) came and went before a solution was found. Now the same problem has encountered and the service department are downright rude and do not want to assist. The problem? The dishwasher is not waterproof (!) and any water that gets in the top burns out the programmer (a new part is £145ish). I would suggest a) do not buy a smeg dishwasher or any Smeg appliance if these guys service it and b) if you do, do not place it near your sink as water may get into it!
