What Drain means on a Dacor dishwasher

The Drain error code on a Dacor dishwasher indicates that the pressure switch remained in the closed position after two complete drain cycles. The pressure switch monitors water level in the sump area at the bottom of the tub. When water is present above a threshold level, the switch closes. If two full drain attempts fail to open the switch, the control board registers this fault, signaling that standing water remains in the sump and drainage has not been achieved.

The most common causes involve blockages in the drain path or a mechanical failure within the drain system. A clogged drain filter, a kinked or obstructed drain hose, a blocked garbage disposal connection, or a failed drain pump can all prevent adequate water removal. In some cases, the pressure switch itself may be faulty, remaining closed even after the sump has been emptied, which would falsely trigger this error.

Diagnosing this fault begins with a reset: pressing the Cancel key twice will clear the error and allow the dishwasher to attempt another drain. If the conditions causing the fault have not been resolved, the Drain error will reappear during the next drain phase of any cycle. A thorough inspection of the drain filter, drain hose routing, pump operation, and pressure switch function is required to identify and correct the underlying problem before normal operation can resume.

Common causes of Drain

  1. 01

    Clogged drain filter or sump

    Wiring / connection

    Food debris and grease accumulate in the filter assembly at the bottom of the tub, restricting water flow out of the sump. Remove and clean the filter screen and check for debris packed around the drain inlet.

  2. 02

    Blocked or kinked drain hose

    Wiring / connection

    The drain hose may be kinked, pinched behind the dishwasher, or clogged with grease buildup. Inspect the full length of the hose from the pump to the sink drain or garbage disposal connection.

  3. 03

    Failed or obstructed drain pump

    Part replacement

    The drain pump motor may have failed or a small piece of debris may be jamming the pump impeller, preventing it from moving water. Listen for the pump attempting to run during the drain cycle and check the impeller for obstructions.

  4. 04

    Garbage disposal knockout not removed or blocked connection

    Wiring / connection

    If the dishwasher drains into a garbage disposal, the factory knockout plug may not have been removed, or the disposal inlet may be clogged. Check the disposal connection point for blockage.

  5. 05

    Faulty pressure switch

    Part replacement

    The pressure switch may be defective and staying in the closed position even after water has been successfully drained, causing a false Drain fault. If all drain components check out and the tub is visibly empty, the pressure switch should be tested and replaced if it does not open correctly.

Frequently asked questions about Drain

What does Drain mean on a Dacor dishwasher?
The Drain error means the dishwasher's pressure switch remained closed after two full drain attempts, indicating the control board detected water still present in the sump. The dishwasher stops the cycle to prevent further issues. This fault points to a drainage problem somewhere between the sump and the household drain connection, or potentially a faulty pressure switch.
Will resetting the Dacor dishwasher clear the Drain error?
Pressing the Cancel key twice will reset the fault and allow the dishwasher to try draining again. However, if the underlying cause has not been corrected, the Drain error will return during the next drain phase. The reset is a starting point for diagnosis, not a permanent fix.
How do I fix the Drain error on my Dacor dishwasher?
Start by cleaning the drain filter located at the bottom of the tub, then check the drain hose for kinks or blockages. Verify that the garbage disposal connection is clear and that the disposal knockout plug was removed during installation. If those steps do not resolve the issue, the drain pump or pressure switch may need to be tested and replaced.
Is the Drain error on a Dacor dishwasher a safety concern?
Standing water in the sump is not an immediate safety hazard, but leaving the condition unaddressed can lead to odors, mold growth, and potential leaks if the machine is run in a degraded state. The dishwasher halts the cycle specifically to prevent overflow, so avoid running it again until the drain path is confirmed to be clear.
How much does it cost to repair a Dacor dishwasher Drain error?
If the fix is simply cleaning a clogged filter or clearing a blocked hose, the repair costs nothing beyond your time. If a drain pump replacement is needed, parts and labor typically range from around $150 to $350 depending on your location and service provider. A faulty pressure switch is generally a less expensive component, with total repair costs usually falling in the lower end of that range.
