Filling error

Kenmore codesKenmore dishwasher codes

Filling error — the dishwasher is unable to fill with water properly.

First step from the service manual

Check if water supply is turned on and water pressure is between 15-145 psi; check if water inlet screen is blocked.

What E3 means on a Kenmore dishwasher

The E3 error code on a Kenmore dishwasher indicates a filling error, meaning the control system has detected that the tub is not reaching the required water level within the expected time frame. The dishwasher monitors fill progress during the inlet phase of each cycle, and when the float switch or water level sensor does not confirm adequate water within the programmed window, the control board triggers E3 and halts the cycle to prevent dry operation of the wash pump.

The fill system relies on several components working together: the water supply line, the inlet valve screen, the water inlet valve solenoid, the door seal, and the water level sensor or float assembly. If any of these fail or are restricted, water will not enter the tub fast enough or at all. Water pressure is a critical factor here. Kenmore specifies that supply pressure must fall between 15 and 145 psi for proper inlet valve operation. Pressure below this range can prevent the valve from opening fully, resulting in a slow fill that times out and triggers E3.

The water inlet valve screen is a frequent culprit, particularly in areas with hard water or sediment in the supply lines. This small mesh screen sits at the valve inlet connection and can accumulate mineral deposits and debris over time, reducing flow to a trickle. Beyond the screen, a failed inlet valve solenoid, a stuck float switch reading a false full condition, or a kinked supply hose can all produce the same E3 fault. Diagnosing the code requires methodically ruling out supply-side issues before moving to component-level testing.

Common causes of E3

  1. 01

    Closed or restricted water supply valve

    Wiring / connection

    The shutoff valve under the sink may be partially or fully closed, blocking water flow to the dishwasher. Check that the valve is fully open and that no kinking is present in the supply hose.

  2. 02

    Clogged water inlet valve screen

    Wiring / connection

    A mesh screen at the inlet of the water inlet valve collects sediment and mineral deposits over time. A blocked screen severely restricts flow and is one of the most common causes of E3. The screen can often be cleaned in place after shutting off the water supply.

  3. 03

    Water pressure out of range

    Wiring / connection

    Supply pressure must be between 15 and 145 psi for the inlet valve to operate correctly. Pressure below 15 psi will prevent adequate fill speed. Use a pressure gauge on a nearby faucet to confirm pressure is within spec.

  4. 04

    Failed water inlet valve solenoid

    Part replacement

    The inlet valve solenoid opens electrically to allow water into the tub. If the solenoid coil has failed or the valve body is stuck, water will not enter regardless of supply pressure. A failed valve requires replacement.

  5. 05

    Stuck or faulty float switch

    Part replacement

    The float switch monitors water level inside the tub. If the float is stuck in the raised position or the switch contacts are faulty, the control board may receive a false signal indicating the tub is already full, preventing the fill cycle from starting or completing.

Frequently asked questions about E3

What does E3 mean on a Kenmore dishwasher?
E3 on a Kenmore dishwasher is a filling error code. It means the dishwasher was unable to fill with water properly during the inlet phase of the cycle. The control board detected that the required water level was not reached within the allotted time, so it stopped the cycle to protect the wash pump from running dry.
How do I fix the E3 error code on my Kenmore dishwasher?
Start by confirming the water supply valve under the sink is fully open and that water pressure at the supply line is between 15 and 145 psi. Next, shut off the water supply and inspect the inlet screen on the water inlet valve for sediment or debris, cleaning it if necessary. If the supply and screen check out, the water inlet valve solenoid or float switch may need testing and possible replacement.
Is it safe to keep using my Kenmore dishwasher when E3 is displayed?
No, you should not attempt to run a wash cycle while E3 is active. The dishwasher halts operation because it cannot confirm adequate water in the tub. Running the wash pump without water can damage the pump motor and other internal components. Resolve the filling issue before resuming normal use.
How much does it cost to repair a Kenmore dishwasher E3 error?
If the fix is simply cleaning the inlet screen or opening a supply valve, the repair costs nothing beyond your time. If the water inlet valve solenoid needs replacement, parts typically range from $25 to $75 depending on the model, with labor adding $75 to $150 if a technician is involved. A float switch replacement is generally in a similar parts cost range.
Will resetting my Kenmore dishwasher clear the E3 error code?
Resetting the dishwasher by cutting power at the circuit breaker for a few minutes may clear the E3 code temporarily, but it will return as soon as the dishwasher attempts another fill cycle if the underlying problem has not been fixed. A reset is useful for confirming whether the fault is persistent, but it is not a repair. Address the root cause of the filling issue to permanently clear the code.
