Viking Dishwasher Error Code E:07

Water inlet valve fault

Viking codesViking dishwasher codes

Water inlet valve fault — water counter pulses are received at a step other than water inlet, indicating the valve may be stuck open or weeping.

First step from the service manual

Check for malfunction of water inlet valve (stuck open or weeping), low water pressure, or faulty electronics. Software drives drain pump for 1 minute then rechecks.

What E:07 means on a Viking dishwasher

The E:07 error code on a Viking dishwasher indicates a water inlet valve fault detected through pulse counting. The control board monitors water flow using counter pulses, and during normal operation, water intake should only occur during designated inlet steps of the wash cycle. When the board detects water counter pulses arriving during a step that is not a water inlet phase, it flags this as an E:07 fault. This pattern indicates that water is entering the tub when it should not be, pointing directly to a valve that is stuck open or weeping (allowing a slow, unintended flow of water through the valve seat).

The water inlet valve is an electrically controlled solenoid component. When the solenoid is de-energized, the valve should close completely and stop all water flow. A valve that is stuck open or weeping fails to seal properly, either due to debris lodged in the valve seat, a deteriorated rubber diaphragm, or a failed solenoid. Low water supply pressure can also contribute to abnormal valve behavior in some cases, as can a fault in the control electronics that incorrectly signals the valve.

As part of its diagnostic routine, the software responds to an E:07 condition by activating the drain pump for approximately one minute to remove any unintended water accumulation, then rechecks for the fault condition. If the problem persists after this automated drain cycle, the error remains active. Technicians should prioritize inspecting the inlet valve for physical failure before condemning the control board, as valve failure is the most common root cause of this specific fault pattern.

Common causes of E:07

  1. 01

    Stuck or weeping water inlet valve

    Part replacement

    The solenoid valve fails to close completely due to a worn diaphragm, debris on the valve seat, or a degraded seal, allowing water to trickle into the tub during non-fill cycle steps. Inspect the valve for continuous dripping or hissing when the dishwasher is idle.

  2. 02

    Debris lodged in the valve seat

    Wiring / connection

    Mineral deposits or particles from the supply line can become trapped in the inlet valve seat, preventing full closure. This can sometimes be resolved by cleaning the valve screen, but often the valve requires replacement.

  3. 03

    Low water supply pressure

    Wiring / connection

    Abnormally low inlet water pressure can cause erratic valve behavior and irregular flow pulses that the control board interprets as a fault. Verify that household supply pressure at the valve connection meets the dishwasher's requirements.

  4. 04

    Faulty control electronics

    Part replacement

    A defect in the control board may cause it to misread flow counter pulses or incorrectly energize the inlet valve solenoid during the wrong cycle phase. This is less common and should be considered after the inlet valve and supply pressure have been ruled out.

Frequently asked questions about E:07

What does E:07 mean on a Viking dishwasher?
E:07 on a Viking dishwasher indicates a water inlet valve fault where the control board detects water flow pulses occurring during a cycle phase when no water should be entering the tub. This typically means the inlet valve is stuck open or weeping water past its seal. The dishwasher will automatically run the drain pump for about one minute and then recheck the condition before displaying the error.
Can I fix the E:07 error myself?
A knowledgeable DIYer can inspect the water supply line, check for adequate water pressure, and examine the inlet valve screen for debris. Replacing the water inlet valve is a moderately involved repair that requires shutting off the water supply and disconnecting electrical connectors, and is within reach for experienced DIYers. If the valve is not the issue, diagnosing a faulty control board typically requires professional testing equipment.
Will resetting the dishwasher clear the E:07 error?
A power reset may temporarily clear the error code, but if the underlying inlet valve fault remains, the E:07 code will return once the dishwasher runs through a cycle and the control board detects water pulses during the wrong phase again. A reset should only be used as a diagnostic step to confirm whether the fault is intermittent, not as a permanent solution.
Is it safe to use my Viking dishwasher while E:07 is showing?
Running the dishwasher with an active E:07 fault is not recommended. A valve that is stuck open or weeping can allow water to accumulate in the tub uncontrollably, increasing the risk of an overflow or water damage to surrounding cabinetry and flooring. It is best to keep the dishwasher off until the inlet valve has been inspected and repaired.
How much does it cost to repair a Viking dishwasher E:07 error?
If the water inlet valve is the cause, parts typically range from $30 to $90 depending on the specific model, with professional labor adding $75 to $200 or more depending on your region and service provider. If the fault is traced to the control board, repair costs can be significantly higher, generally ranging from $150 to $400 or more for parts and labor combined.
