Error Codes (undefined): Troubleshooting, Fixes & Prevention Tips explained below.

What Circulation Pump Error Indicates❓

The Circulation Pump Error means the dishwasher is failing to properly circulate water throughout the wash cycle. The circulation pump is essential for pushing water through the spray arms to clean the dishes thoroughly. If this pump malfunctions or stops working, the dishwasher will not spray water efficiently, resulting in dirty or partially cleaned dishes. This issue can be caused by mechanical failure, electrical faults, or blockages within the pump system. It is important to address this error promptly to avoid further damage to the appliance.
