Is my timer motor broken?

Dishwasher Repair
1

Hi,

My old hotpoint dishwasher has suddenly stopped doing anything.

I have confirmed that it is not the door switch or the power cord, as there is power coming all the way up to the selector switch and timer motor, when I have it plugged in.

I suspect the timer motor, but am a little uncertain as to whether I am testing the correct wires. There is an array with many wires that leads from the side of the timer motor over to the selector switch and down towards the motor pump mechanism; a plastic connector (a more modern looking electrical part) that leads two wires (a white and a yellow) into the timer motor; and one green wire with an older style metal connector which should be the ground AFAIK. I tested the two wires with the modern looking plastic connector for continuity, and my multimeter didn’t change a bit. Does this confirm that the timer motor needs to be replaced, or are there further tests I should run to confirm that the timer motor is the problem?

Thank you for your assistance,
Jeanne

I would turn it on and check for voltage to the watrer solenoid. Post results.

I have not had an opportunity to check the water solenoid yet (not sure where/what it is).

However, since my husband was nagging me to do SOMETHING with it, I ordered a new timer motor on Friday, received and installed it on Saturday, and my washing machine worked!..until tonight, when it again does nothing when I turn the timer knob.

I’m a little disheartened, and am afraid that whatever is going on has burned out the new timer motor. There is no schematic for the machine, and it is so old (15 years?) that I don’t know whether anyone will have one for me to look at to figure this out.

The model number is Hotpoint HDA3400F00BB.

Next step? Thank you for your assistance.
