i have a CDA dishwasher - early into the cycle it stops working and bleeps continuously until i open the door. the rinse light is then 'on' and trhe start button light flashes continuously. I can reset and it all happens again. I have done the test prog (as someone kindly suggested on another forum) and the light flashes 4 times. However no one else has been able to help me further.............any suggestions would be much appreciated. Jen model CW497
