dishwasher pump is running continuously even with the door open?

I have this problem. You will prob find the machine is both filling and emptying at the same time. My investigations suggest the problem is the water flow meter/sensor. On my Bosch sgs43e02gb/45 this is in the bottom rear and in the centre so impossible access without a serious dismantling of the machine - I'm contemplating this as I type. The replacement part is on Ebay for about £15
