I have an old - probably 10 years- technik dishwasher which was supplied with my fitted kitchen and is built in. Not sure what model but pretty basic, only has 3 washes 55,65 and eco. It has suddenly stopped working properly. There appears to be no water getting into the machine though I have checked that the supply to the hose is still there. Also the programme continues even when you open the door whereas it normally stops. Any ideas?
