Viking Dishwasher Error Code E:02

No water fault

Viking codesViking dishwasher codes

No water fault — during the water inlet step, no pulses are sensed from the water counter (flow meter); the dishwasher waits until a water signal is detected.

First step from the service manual

Check for malfunction of water inlet valve, no water supply, insufficient water pressure, cable harness errors, or faulty electronics.

What E:02 means on a Viking dishwasher

The E:02 error code on a Viking dishwasher indicates a no-water fault. This code triggers during the water inlet phase of the wash cycle when the control board receives no pulse signals from the flow meter, also called the water counter. The flow meter is a sensor installed in the water supply line that generates electrical pulses as water passes through it. If the control board does not detect any pulses within the expected time window, it interprets this as a failure to fill and holds the cycle in a wait state until a water signal is detected or the fault is cleared.

The most common root causes fall into a few categories: water supply problems, component failures, and wiring issues. On the supply side, a closed shutoff valve, low household water pressure, or a kinked inlet hose can prevent water from reaching the valve entirely. The water inlet valve itself is a frequent failure point as well. If its solenoid coil has failed or its internal screen is clogged with mineral deposits, it will not open properly and no flow will reach the flow meter.

Beyond the mechanical components, E:02 can also result from electrical faults. A broken or disconnected wire in the harness between the flow meter and the control board will prevent pulse signals from reaching the board even if water is flowing normally. A failed flow meter that does not generate pulses, or a faulty control board that cannot process incoming signals, are also possible causes. Diagnosis should proceed from the simplest checks first, confirming water supply pressure and valve operation, before moving to electrical continuity testing of the harness and sensor.

Common causes of E:02

  1. 01

    No or insufficient water supply

    Wiring / connection

    The shutoff valve under the sink may be closed, or household water pressure may be too low for the inlet valve to open fully. Check that the supply valve is fully open and verify adequate water pressure at the connection point.

  2. 02

    Clogged or failed water inlet valve

    Part replacement

    The inlet valve screen can become blocked with mineral scale or debris, restricting flow to the point where the flow meter detects nothing. The solenoid coil inside the valve can also burn out, preventing the valve from opening at all. A failed valve will need to be replaced.

  3. 03

    Faulty flow meter

    Part replacement

    The flow meter generates electrical pulses as water passes through it, and if the sensor has failed internally, it will not send any signal to the control board even when water is flowing. Replacing the flow meter resolves this condition.

  4. 04

    Cable harness wiring fault

    Wiring / connection

    A broken wire, corroded connector, or loose terminal in the harness between the flow meter and the control board can interrupt the pulse signal. Inspect the harness visually and test continuity with a multimeter along the relevant circuit.

  5. 05

    Faulty control board

    Part replacement

    If the control board cannot process or receive the pulse signals from the flow meter, it will report E:02 even when all other components are functioning correctly. This is the least common cause and should be diagnosed only after all other components have been ruled out.

Frequently asked questions about E:02

What does E:02 mean on a Viking dishwasher?
E:02 is a no-water fault that appears when the dishwasher does not detect any pulse signals from the flow meter during the water inlet step. The control board monitors the flow meter to confirm water is entering the unit, and if no pulses are sensed within the expected time, it sets this code and holds the cycle. The cause can range from a simple supply issue to a failed valve, sensor, or wiring problem.
How do I fix the E:02 error on my Viking dishwasher?
Start by confirming the water supply shutoff valve is fully open and that the inlet hose is not kinked or blocked. If the supply is fine, the next step is to inspect the water inlet valve for a clogged screen or failed solenoid. After that, check the wiring harness connected to the flow meter for any broken or disconnected wires. If wiring and the valve are both intact, the flow meter or control board may need to be tested and replaced.
Is it safe to keep using my dishwasher when it shows E:02?
The dishwasher will not continue the wash cycle while E:02 is active since it is waiting for a water signal, so there is no immediate safety risk from running it in this condition. However, you should address the fault before attempting normal use to avoid strain on the pump and other components. Do not try to force a cycle to complete while the error is present.
Will resetting the dishwasher clear the E:02 error?
A power reset may clear the code temporarily, but if the underlying cause is not corrected, E:02 will return as soon as the dishwasher attempts to fill again. Resetting is useful as a first step to confirm whether the fault is intermittent, but it is not a repair. The component or supply issue causing the no-water condition must be identified and corrected.
How much does it cost to repair a Viking dishwasher showing E:02?
Repair costs depend on which component has failed. If the fix is simply opening a shutoff valve or clearing a kinked hose, there is no parts cost involved. Replacing a water inlet valve typically runs in the range of $80 to $200 for parts, while a flow meter replacement is generally in a similar range. Control board replacement is the most expensive possibility, often ranging from $200 to $500 or more for parts alone, not including labor.
