Jackson dishwasher shows E5 and stops mid-cycle; wash pump does not start or stops shortly after starting.

Safety first: Disconnect power and allow the machine to cool. High-voltage and rotating components are present.

• Check for obstructions: Remove tank strainers and access the wash pump inlet. Look for broken glass, cutlery, or plastic blocking the inlet. Clear any debris.
• Inspect wash pump impeller: Access the wash pump housing (usually under the tank). Remove the cover and inspect the impeller for damage or binding. Ensure it rotates freely by hand. Remove any foreign objects.
• Reset motor overload: Many Jackson wash pumps have a manual-reset overload on the motor or in the control box. Locate and press the reset button if tripped. Investigate cause of overload (e.g., jammed impeller, low voltage).
• Test motor windings: With power off, measure resistance across motor terminals. Compare to specifications. An open or shorted winding indicates a failed motor that must be replaced.
• Verify contactor operation: Inspect the wash pump contactor for burned contacts or loose wiring. Replace if the contactor fails to pull in when the cycle starts.

If the pump continues to trip or fail, the motor may be undersized for the load due to mechanical binding or incorrect replacement parts; consult Jackson service documentation.
