The Magic Chef dishwasher with Temp booster does not drain. I have never used it since I bought this apartment. Dishwasher was used and I never got the manual and don't know where is the serial number nor how to run this dishwasher ! I only use this washer to stack my hand washed dishes and water accumulates when I wash manually the dishwasher and manually have to empty it. Please help. How do I unclog it and know which manual to download? Thanks Vera
