Dishwasher Won’t Start, Stops Mid-Cycle, or Shows Error Codes? The Control Board Is the Most Common Cause.

When the dishwasher control board fails, the appliance loses its brain — cycles won’t initiate, the machine stops mid-wash, buttons become unresponsive, or error codes appear with no clear cause. The 99003616 is the direct-replacement control board (PCB) for compatible Maytag and Whirlpool dishwashers, restoring precise cycle sequencing, reliable heating, and consistent pump and valve control.

Symptoms of a Failed Dishwasher Control Board

• Dishwasher won’t start at all — no response when pressing Start
• Cycle stops partway through and won’t resume
• Control panel buttons unresponsive or erratic
• Dishwasher runs continuously without completing a cycle
• Error codes displayed on the control panel
• Dishwasher fills but won’t wash or drain
• Heating element not activating — dishes not drying
• Pump or spray arms not operating during wash cycle
• Lights flashing or display behaving erratically
• Dishwasher starts randomly or at wrong times

Installation Notes

New vs. Used — Which Option Is Right for You?

The New variant is a fresh OEM-spec replacement board — ideal when you want full service life and peace of mind.
