KitchenAid Dishwasher Error Code 8 Blinks

The 8 Blinks code indicates that the dishwasher detected low or no water during the fill cycle. The control board monitors incoming water and shuts down the machine when it cannot confirm adequate fill within the expected timeframe. This is a protective fault designed to prevent pump and heating element damage from running dry.

You should not continue running the dishwasher while this error is active. Without adequate water, the pump and heating element can overheat and sustain permanent damage. The dishwasher halts operation precisely to prevent this, so resolve the fill issue before running another cycle.

Repair costs depend on the failed component. If the issue is simply a closed supply valve or a stuck float, there may be no parts cost at all. Replacing a water inlet valve typically involves parts costs in the range of $25 to $80, plus labor if a technician is hired. A control board replacement, if needed, can raise total repair costs significantly, generally falling in the $150 to $350 range for parts and labor combined.

Start by checking that the water supply valve under the sink is fully open and that the supply hose is not kinked. Next, inspect the float switch inside the tub to make sure it moves freely and is not stuck in the raised position. If those checks pass, the water inlet valve itself may need to be tested for continuity or replaced. Following the "Will Not Fill" troubleshooting steps in order will help isolate the exact cause.

A reset may clear the error code temporarily, but if the underlying fill problem is not corrected, the 8 Blinks fault will return as soon as the dishwasher attempts to fill again. Address the root cause first, such as a closed supply valve, stuck float, or faulty inlet valve, before relying on a reset to restore normal operation.
