Neff dishwasher S4456N4GB/35 FD 8310 000028 stopped mid cycle. There's no display but mains is good. I managed to empty it by removing the left side cover and operating a switch lever. Taking the front panel off I saw scorch marks. The control board has blown TY3 which seems to be a triac. Similar (intact) devices have Z7SY317printed on them. Do you know what that is, what it drives and if there is a locally available equivalent part?
