The dishwasher was in the middle of its cycle and just stopped working.
Will not restart..
Here are your parts
Replacement parts for JENN-AIR JDB1270AWY | AppliancePartsPros.com
I am assuming the unit is totally dead.
First is to check that the breaker has not tripped.
Next make sure the unit is getting power, you will need a meter for this.
A while back I had a run of people who had bad murett (wire nut) connections under the unit.
Next would be to check the door latch switches.
Had to clean contacts on ribbon for control panel in front door with denatured alcohol.
Also parts listed for this dishwasher don’t all match up. Found parts for top rack and water distribution from model MDBTT79AWW
