SOURCE: Unit not pumping on wash cycle
Could be bad main wash pump motor, bad capacitor on said motor, or broken or jamed pump impeller. You will need to remove the lower spray arm and filter assembly to get access to the pump impeller to see if it is jammed or broken. If you can turn the motor shaft but the motor just hums then the motor of motor start capacitor is gone. You can order the motor with start capacitor and impeller for around $130. Check for 120v at the motor terminals prior to replacing motor/pump assembly to confirm, 120v at motor would but motor not turning equals bad motor and or capacitor.

I can see from what you have described (by the way it is a very clear and precise description which is very helpful), there is a problem in the water circulation system. These dishwashers use an alternating water flow method to split the water circulation between lower and upper wash arms in alternate cycles.
The way it is done is by use of a small ball that reciprocates between two holes in the water distributor. See item 58 in this diagram. It is possible this ball is blocking the pump impeller and causing the grinding noise.
You will have to open the assembly and check it out. You may need to replace some of the parts if the damage is too severe as there is a degree of precision required for the water jet to go through the right contour to create the flow.
Good luck. Take photographs at each stage so that you know what goes where.

You most likely have a fault with the Thermostat. That is common on Omega Technowash which is similar to a Smeg dishwasher. More often than not the Thermostat fails rather than the heat element. However, not to completely dismiss a failed heat element.
The thermostat is not very expensive. If you don't have the means to test the element or thermostat via a multimeter, you can order the thermostat to have a go at fixing it yourself.
Unplug the machine from its power point.
"Two screws in the front kick plate. Open these and lift off kick plate. When you open the dishwasher door you will see an L-shaped heat element which is on the bottom of the bowl on the left and back of machine. The Thermostat is the round metal head situated on the front left in between the element coils. When you look from underneath inside where you have removed the kick-plate you can see two wires going to your heat element and 4 wires going to the Thermostat (either 2 White and 2 purpule) or (2 red and 2 white).
The thermostat is pushed in from the bottom and sits in a groove of a rubber seal. You can pull it down and out from underneathe and twist and push up the replacement in its place. Make sure the sharp metal edge of thermostat is poped insided the groove, otherwise the machine will leak.
Try this first, I am fairly sure it is the thermostat. If you have a multimeter you can check continuity of the heat element.
If you think this solution helped you please vote 4 thumbs up and give me a testimonial.
