About this drain problem
What can cause this problem?
Dishwasher drainage depends on the appliance, its drain connection, and the kitchen drain system.
If the appliance is operating but water cannot leave through the drain, the restriction may be in the drain connection or line.
A-1 Drain Cleaning handles the drain side of the problem; appliance-specific failures may require an appliance technician.
Signs the drain may be involved
- Water remains in the dishwasher after a cycle
- The kitchen sink fills when the dishwasher drains
- Dirty water comes back into the sink
