Can anyone help me with a problem on a Smeg DWD1SSE-1 dishwasher. On programme 4 (Eco not selected) the machine stops after approximately 22 minutes. The Eco light is on and the programme display shows the selected programme number. Occasionally the machine will complete the programme normally.
The heater, wash & dain pumps are all operating. I have also checked the door wiring for breaks. A faulty thermistor maybe?
