Hi - I have a Bosch Dishwasher that has just had a new pump fitted but now it wont start its wash cycle - I called out the engineer after coming back from holiday and he wouldnt come back out as he said that he left it working fine! I wasnt present when he initially fixed it! Not sure whether it is worth just spending a bit extra money and buying a brand new one? Can anyone give me any clues as to what migbht be the problem?
