did the unit start the programme and fill ? if no

this unit uses a 3 phase drain pump and senses the current to the pump to determine if the unit is empty. if the pump is worn the current increases and the unit wrongly assumes it is still full

Re: bosch dishwasher sms40c02gb/03

Is this at start up ? The start up procedure for these machines is as follows.
After start button operated:
Drain pump runs for approx 1 min.
Pause
Heat pump runs for approx 10secs.
Pause.
1 sec burst of water.
Pause
Then it starts filling.
You can get a fail to start with something as simple as the drain pump access lid being loose or out of position.
Hope this helps.
