I have a new Kenwood KDW60X10 dishwasher, not yet used. it is plumbed in, the water inlet is on, the waste is installed according to instructions, but I keep getting an error message of E1, meaning that either the water tap is turned on (it is) of that the flow meter is broken. What and where is the flow meter? I have interrupted the programme because of a leak, so is it possible the machine needs to be reset, if so, how?
