How old is my Hotpoint dishwasher, model HDA3400G02WW Serial SG8047194 is??? My dishwasher humms, but doesn't runs at ALL. What could be the problem????

You would need the model number not the serial number.

Check and see if during the heating cycle there is voltage to the element. If not, you will need to replace the control board/module. from serial number 41011 part no is c00143209, to serial no 41011 part no is c00143207

This may be one of the models that were recalled for timer problems. You may want to
check the serial number inside the door on the upper left and google that number for
recall information. This may also be a problem with the drain solenoid, as they were a
high failure item for about a year. (if you manually rotate the timer and hear a "thunk"
then the solenoid IS working) if not, then secure power and remove lower cover (four
1/4 inch hex screws) and see if the shiny shaft moves freely. If it doesn't then it's
bad and the machine is trying to fill while pumping out the fill water. It can be removed
by removing the "C" clip and two philips head screws behind and slide the whole assembly
forward to remove. They cost around 20 to 40 dollars depending on vendor.
Hope this helps.

well models and serial numbers are all well and good but there can be no help until you tell us what make it is

Thank you

dear sir the problem you have sounds like the solenoid that opens the drain actuater can be worn out open the bottom panel run tru a cycle observe when the solenoid open it may be that there is something causing the solenoid to buzz either worn out or a wire or something in the way causing not to close proprly thanks from gilles

Certainly sounds like the motor is seized. If it is quite old it may not be worth fixing, you should call your local appliance parts dealer with the dishwasher model and serial number and get a quote for a new motor.

A noise could be created by something getting down into the motor-pump assembly piece of glass, piece of bone, wire tie anything really. If this is the case and you can remove it before it causes further damage problem solved. At ten years old the problem may be the motor and or pump one thing to consider before putting money into it is disheashers average 7-10 years these days. Good Luck.
