Sharp Dishwasher Error Code E1

E1 on a Sharp dishwasher means the flow meter did not detect the required amount of water entering the tub within a 4-minute fill period. The dishwasher monitors water intake using a flow meter, and when the expected volume is not reached in time, the cycle stops and E1 is displayed. This is a water inlet fault that points to issues in the water supply path, the inlet valve, or the flow meter itself.

You should not attempt to run the dishwasher while E1 is active. The error indicates the machine did not fill properly, and running a cycle without adequate water can damage the pump and heating element. Address the underlying cause before resuming normal operation.

If the fix is simply opening a closed supply valve or cleaning the inlet screen, there is no parts cost. Replacing a water inlet solenoid valve typically runs in the range of $30 to $80 for the part, while a flow meter replacement can cost $20 to $60 in parts. Adding professional labor, total repair costs generally range from $100 to $250 depending on the specific component and local service rates.

Start by checking that the water supply valve under the sink is fully open and that the inlet hose is not kinked. Next, inspect the inlet valve screen for clogs and clean it if needed. If the supply and screen are both clear, the water inlet solenoid valve or flow meter may need to be tested and potentially replaced.

A reset may temporarily clear the E1 code, but the error will return if the underlying problem is not resolved. If the water supply issue, clogged screen, or faulty component is still present, the flow meter will again fail to register sufficient fill volume and E1 will appear on the next cycle.
