Kenmore Dishwasher Error Code E3

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.

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.

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.

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.

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.
