Dishwasher shows E19; diverter may not change spray zones, and cleaning in upper or lower rack is poor.

Safety first: Turn off power and water before accessing the bottom of the dishwasher.

• Confirm spray pattern issue: Run a cycle and check if only one rack is getting clean while the other remains dirty. E19 often indicates diverter problems.
• Access the diverter assembly: Remove the lower access panel and locate the diverter motor on the sump or circulation pump housing.
• Inspect for obstructions: Remove the diverter cover and check for broken plastic, food debris, or foreign objects preventing the disc from rotating.
• Test diverter motor: Measure resistance across the motor terminals. Replace the Dacor diverter motor if open or shorted.
• Reassemble and test: After cleaning or replacing parts, run a service cycle to verify that E19 is cleared and both racks are being washed.
