What PC Means
PC is listed for Dacor’s Modernist DDW24M999 and DDW24T999 dishwashers as a zone wash function check. It relates to the ZoneBooster or zone-wash diverter that sends water to particular parts of the racks.
Common Causes of PC
- Zone wash diverter motor sticking
- Diverter position sensing problem
- Obstruction in the lower wash area
🔧 One Safe Check You Can Try
Turn the dishwasher off and try to start it again. Make sure nothing is blocking the spray arms or the WaterWall reflector track. If PC continues, contact service.
⚠ Why You Shouldn't Go Further Than That
- The diverter assembly sits in the sump; replacing it means taking the lower wash system apart.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
