What ECONO WASH + LED3 means on a Viking dishwasher

The ECONO WASH + LED3 error code on a Viking dishwasher indicates a cycle error specifically tied to a drain fault that occurred during the drain cycle operation. This means the control system detected that water was not evacuating the tub within the expected timeframe or that the drain cycle failed to complete successfully. The dishwasher's control board monitors drain performance and triggers this code when the drain sequence does not meet its programmed parameters.

The drain system involves several components that can contribute to this fault: the drain pump motor, the drain solenoid or valve, the drain hose routing, and the wiring connections between these components and the main control board. A blockage anywhere along the drain path is a frequent culprit, but electrical failures in the pump circuit can produce the same symptom. The control board interprets a failed or incomplete drain cycle as an error condition and halts operation to prevent potential overflow or water damage.

The first recommended diagnostic step is a normal reset and test. This involves cutting power to the unit, waiting briefly, restoring power, and running a test cycle to determine if the fault was a transient condition or a repeatable failure. If the error returns consistently, a more thorough inspection of the drain pump, drain hose, filter assembly, and associated wiring is warranted before condemning any single component.

Common causes of ECONO WASH + LED3

  1. 01

    Clogged drain filter or sump area

    Wiring / connection

    Food debris, broken glass, or buildup in the filter basket and sump can restrict water flow enough to prevent proper draining. Remove and inspect the filter assembly at the bottom of the tub for blockages.

  2. 02

    Blocked or kinked drain hose

    Wiring / connection

    The drain hose can become kinked behind the unit or clogged with grease and debris, preventing water from reaching the sink drain or disposal. Inspect the full length of the hose for physical obstructions or bends.

  3. 03

    Failed drain pump motor

    Part replacement

    If the drain pump motor has seized, burned out, or lost electrical continuity, it will not move water out of the tub regardless of the control board's commands. The pump should be tested for proper operation and electrical continuity.

  4. 04

    Faulty drain pump wiring or connector

    Wiring / connection

    Corroded, loose, or damaged wiring connections between the drain pump and the control board can interrupt the signal or power needed to run the drain cycle. Inspect connectors at both the pump and control board ends for damage or moisture intrusion.

  5. 05

    Garbage disposal or sink drain obstruction

    Wiring / connection

    If the dishwasher drains into a garbage disposal, a clogged disposal or an uncapped knockout plug can prevent water from exiting the dishwasher. Check that the disposal is clear and that the dishwasher inlet port is open.

Frequently asked questions about ECONO WASH + LED3

What does ECONO WASH + LED3 mean on a Viking dishwasher?
The ECONO WASH + LED3 combination indicates a cycle error caused by a drain fault during the drain cycle operation. The dishwasher detected that draining did not complete as expected and stopped the cycle. This can be caused by a blockage, a pump failure, or a wiring issue in the drain circuit. A reset and test cycle is the recommended first step to determine if the fault is recurring.
Will resetting my Viking dishwasher clear the ECONO WASH + LED3 error?
A reset may clear the error temporarily if the fault was caused by a transient condition such as a brief obstruction or a control board glitch. To reset, cut power to the dishwasher at the circuit breaker or unplug it, wait a minute or two, then restore power and run a cycle. If the error returns, the underlying drain issue needs to be diagnosed and corrected before the unit will operate reliably.
How do I fix the ECONO WASH + LED3 drain error on my Viking dishwasher?
Start by cleaning the drain filter and sump area at the bottom of the tub, then inspect the drain hose for kinks or blockages. Check that the garbage disposal or sink drain the dishwasher connects to is clear. If the error persists after these checks, the drain pump motor and its wiring connections should be inspected and tested for proper function.
Is it safe to use my Viking dishwasher when the ECONO WASH + LED3 error is showing?
It is not recommended to continue running the dishwasher while this error is active. A drain failure means water may be sitting in the tub and not evacuating properly, which can lead to leaks, odors, or water damage if the unit attempts another cycle. Resolve the drain fault before resuming normal use.
How much does it cost to repair the ECONO WASH + LED3 drain error on a Viking dishwasher?
Repair costs depend on the root cause. Clearing a clogged filter or drain hose is often a no-cost fix you can do yourself. If the drain pump motor needs replacement, parts and labor can range from around $150 to $400 or more depending on your location and service rates. A diagnostic service call alone typically runs between $75 and $150 before any parts are factored in.
