What RINSE HOLD + LED1 means on a Viking dishwasher

The RINSE HOLD + LED1 error on a Viking dishwasher indicates a Low Level Error, meaning the control system has detected that the water level inside the tub has fallen below the minimum threshold required for safe and effective operation. The dishwasher monitors water level through a pressure sensor or float switch assembly, and when the sensed level does not reach the expected point within a set timeframe during filling, the control board flags this fault and halts the cycle to prevent the wash pump from running dry.

The most frequent root causes involve water supply issues or faults in the level-sensing components. A kinked or restricted inlet hose, a clogged inlet valve screen, or insufficient household water pressure can all prevent adequate water from entering the tub. The water inlet solenoid valve itself may also be failing, opening only partially or not at all, which starves the tub of the required fill volume.

Faults within the level detection system are also a common trigger. A stuck or corroded float switch that fails to register the rising water level, or a faulty pressure sensor that sends an incorrect signal to the control board, can cause this error even when water is physically present in the tub at an acceptable level. Beginning diagnostics with a reset and test cycle helps determine whether the fault is intermittent or a persistent hardware failure that requires component-level inspection and repair.

Common causes of RINSE HOLD + LED1

  1. 01

    Restricted or failed water inlet valve

    Part replacement

    The inlet valve screen may be clogged with sediment, or the solenoid valve itself may be failing to open fully, limiting water flow into the tub. Check the valve screen for debris and test the solenoid for proper function.

  2. 02

    Insufficient household water pressure

    Wiring / connection

    Low incoming water pressure can prevent the tub from filling to the required level within the control board's expected timeframe. Verify that the supply shutoff valve under the sink is fully open and that line pressure is adequate.

  3. 03

    Stuck or faulty float switch

    Part replacement

    The float switch assembly can become stuck in the raised position due to debris buildup or corrosion, causing it to incorrectly signal that the tub is already full or that water is present when the level is actually low. Inspect and clean the float for free movement.

  4. 04

    Faulty water level pressure sensor

    Part replacement

    A defective pressure sensor may send an inaccurate low-level reading to the control board even when water fill is normal. This requires testing or replacing the sensor to confirm it is providing correct signals.

  5. 05

    Kinked or blocked inlet supply hose

    Wiring / connection

    A kinked supply hose or a closed shutoff valve can restrict or completely block water flow to the dishwasher. Trace the supply hose from the valve under the sink to the inlet connection and check for kinks or obstructions.

Frequently asked questions about RINSE HOLD + LED1

What does RINSE HOLD + LED1 mean on a Viking dishwasher?
The RINSE HOLD + LED1 combination indicates a Low Level Error, meaning the dishwasher's control system has detected that the water level in the tub is too low to safely operate. The machine halts the cycle to protect the wash pump from running without sufficient water. This fault points to either a water supply problem or a failure in the level-sensing components.
Will resetting the dishwasher clear the RINSE HOLD + LED1 error?
A reset is the recommended first diagnostic step and can clear the error if the fault was caused by a temporary glitch or a momentary drop in water pressure. If the error returns after the reset and test cycle, the underlying cause is a persistent hardware issue such as a clogged inlet valve, a faulty float switch, or a defective pressure sensor that will need hands-on inspection.
How do I fix a Low Level Error on my Viking dishwasher?
Start by resetting the dishwasher and running a test cycle. If the error returns, check that the water supply shutoff valve is fully open and inspect the inlet hose for kinks. Next, examine the inlet valve screen for sediment blockage and test the float switch for free movement and proper operation. If supply and mechanical checks pass, the inlet solenoid valve or the water level pressure sensor may need to be tested and replaced.
Is it safe to continue using my Viking dishwasher when this error appears?
You should not attempt to bypass or ignore this error and continue running cycles. The Low Level Error exists to prevent the wash pump from operating without adequate water, which can cause the pump motor to overheat and fail. Stop using the dishwasher until the cause of the low water level has been identified and corrected.
How much does it cost to repair a Viking dishwasher Low Level Error?
Repair costs vary depending on the failed component. Clearing a clogged inlet valve screen or adjusting the supply valve involves little to no parts cost. Replacing a water inlet solenoid valve or float switch typically runs in the range of $50 to $150 for parts, while a water level pressure sensor replacement can fall in a similar range. Adding professional labor costs, total repair bills commonly range from $100 to $350 depending on diagnosis complexity and your location.
