Re: smeg DWI 710
Your previous posts suggest that this machine has PCB control, but the DWI710 has an electro-mechanical timer. Please re-check the model number.
Assuming that it is a PCB machine, if it were not heating at all you would get a fault code showing. Therefore, the fault lies either with the PCB, or with the water level control. The single commonest SMEG dishwasher problem is underfilling, which will give poor heat and therefore poor wash results. Have a read of this:
