GE Dishwasher Error Code WASH (flashing)

Value models

GE codesGE dishwasher codes

Value models: Drain is blocked so severely that the dishwasher cannot continue to operate; dishwasher will stop. Pump-out time exceeds 400 seconds.

First step from the service manual

Check the air gap, check for a kink in the drain hose, check for stopped-up drains. To pump remaining water: latch door, touch RESET, select desired cycle, touch START and RESET again.

What WASH (flashing) means on a GE dishwasher

On GE value-model dishwashers, a flashing WASH indicator signals a critical drain failure. Specifically, the control detects that the pump-out cycle has exceeded 400 seconds without successfully clearing the water from the tub. At that point, the dishwasher halts operation entirely to prevent overflow, motor damage, or prolonged running of a blocked pump. This is not a soft warning; the machine will not resume its cycle on its own.

The drain system on these dishwashers relies on a drain pump moving water through the drain hose and out through either a garbage disposal connection or a dedicated drain line, often routed through an air gap fitting mounted on the sink deck. Any restriction along this path forces the pump to work longer than the 400-second threshold, triggering the lockout. Common restriction points include a clogged air gap, a kinked or pinched drain hose, a blocked garbage disposal inlet, or a backed-up household drain line.

Once the error has been triggered and the root cause has been corrected, the control offers a manual pump-out sequence to clear the standing water. With the door latched, pressing RESET, selecting a cycle, and then pressing START followed by RESET again commands the unit to attempt another drain cycle. This step is essential before resuming normal operation, as standing water left in the tub will immediately retrigger the fault on the next cycle.

Common causes of WASH (flashing)

  1. 01

    Clogged or blocked air gap

    Wiring / connection

    The air gap fitting on the sink deck collects debris over time and is the most frequent cause of slow or failed draining. Remove the cap and clean out any buildup from the internal passages.

  2. 02

    Kinked or pinched drain hose

    Wiring / connection

    If the dishwasher was recently installed or moved, the drain hose may have developed a kink behind or beneath the unit, severely restricting water flow. Inspect the full length of the hose for sharp bends or compression points.

  3. 03

    Blocked garbage disposal inlet

    Wiring / connection

    When a new garbage disposal is installed, the drain knockout plug is sometimes left in place, completely blocking dishwasher drainage. Also check for food debris packed into the disposal inlet port.

  4. 04

    Stopped-up household drain line

    Wiring / connection

    A slow or fully blocked sink drain prevents dishwasher water from exiting even if the dishwasher components are fully functional. Run the sink and check for sluggish draining as a quick test.

  5. 05

    Faulty or seized drain pump

    Part replacement

    If all external drain path obstructions have been cleared and the error persists, the drain pump itself may be mechanically seized or electrically failed. A seized pump will not be able to move water regardless of how long it runs.

Frequently asked questions about WASH (flashing)

What does WASH (flashing) mean on a GE dishwasher?
A flashing WASH indicator on a GE value-model dishwasher means the drain pump ran for more than 400 seconds without successfully emptying the tub, causing the machine to stop completely. This points to a severe blockage somewhere in the drain path. The dishwasher will not resume the cycle until the blockage is cleared and the remaining water is manually pumped out using the reset procedure.
How do I fix a flashing WASH error on my GE dishwasher?
Start by inspecting the air gap on your sink deck and cleaning out any debris, then check the drain hose for kinks or pinches along its full length, and confirm that the household drain or garbage disposal is not blocked. Once the obstruction is resolved, latch the door, press RESET, select a wash cycle, and then press START followed by RESET again to initiate a manual drain cycle and clear the standing water.
Is it safe to leave a GE dishwasher with a flashing WASH error?
The dishwasher shuts itself down when this error triggers, so it will not continue running or actively overflow on its own. However, standing water left in the tub for an extended period can promote mold growth and odors. It is best to address the drain blockage and pump out the remaining water as soon as possible.
Will resetting my GE dishwasher clear the flashing WASH error?
A simple reset alone will not permanently clear this error if the underlying drain blockage is still present, because the pump-out cycle will exceed 400 seconds again and the fault will return immediately. You must first remove the obstruction from the air gap, drain hose, or household drain line, and then use the specific pump-out sequence (RESET, select cycle, START, RESET) to drain the remaining water before the machine can operate normally.
How much does it cost to repair a GE dishwasher showing a flashing WASH error?
If the problem is a clogged air gap, kinked hose, or blocked household drain, the repair can often be completed at no cost or for a minimal amount spent on cleaning supplies. If the drain pump itself has failed and needs replacement, parts alone can range from roughly $30 to $100 or more depending on availability, with professional labor adding $75 to $200 on top of that depending on your area.
