How to Fix Error E1 — Step by Step
- 1
Reset the Dishwasher
Before attempting any repairs, try resetting the dishwasher by unplugging it from the power outlet for 30 seconds and then plugging it back in. This simple reset can often resolve the issue. Ensure the dishwasher is empty and the door is closed before resetting.
💡 Pro Tip: If you've recently cleaned the filter or checked the drain, try resetting the dishwasher first to ensure the issue isn't related to a previous maintenance task.

Check the Float Switch
Locate the float switch, usually located at the bottom of the dishwasher. Use a multimeter to measure the resistance between the two terminals. The resistance should be around 1-2 kΩ. If the resistance is off or you're unable to measure it, replace the float switch. To access the float switch, remove the lower panel using a Phillips #2 screwdriver. Be cautious of any water damage or electrical components.
💡 Pro Tip: When measuring the resistance, ensure the multimeter is set to the ohms (Ω) function and the leads are securely connected to the terminals.

Inspect the Water Level Sensor
The water level sensor is usually located near the float switch. Use a multimeter to measure the voltage between the two terminals. The voltage should be around 5-6 VDC. If the voltage is off or you're unable to measure it, replace the water level sensor. To access the water level sensor, remove the lower panel using a Torx T20 screwdriver.
💡 Pro Tip: When measuring the voltage, ensure the multimeter is set to the DC voltage function and the leads are securely connected to the terminals.

Check the Drain Hose and Filter
Inspect the drain hose for any kinks or blockages. Ensure it's properly connected to the dishwasher and the sink drain. Check the filter for any debris or blockages. Clean or replace the filter as needed.
💡 Pro Tip: Regularly cleaning the filter and checking the drain hose can help prevent issues like error code E1.

Check for Water Damage

💡 Pro Tip: Water damage can be a serious issue, and it's essential to address it promptly to prevent further damage or potential health risks.
When to Call a Professional
If you're unsure about any of the steps or have difficulty accessing the float switch or water level sensor, reaching out to a certified technician is your best bet. Additionally, if you've detected water damage or the issue persists after attempting the above steps, it's best to seek professional assistance to avoid any potential safety risks or further damage to the dishwasher.
