In this blog post, we’ll break down those codes into simple terms and help you understand what each one means. Let’s decode them together and get your dishwasher back in shape!

How to Fix Common Dishwasher Error Codes: A Simple Guide

1. Error Code E1: Water Supply Issue

What It Means: When you see error code E1 on your dishwasher, it means the machine is not getting enough water. This can happen for a few reasons.

What to Do:

Check the Water Supply: Start by looking at the water tap that connects to your dishwasher. Make sure it is fully open. Sometimes, the tap might be slightly closed, which can stop water from flowing into the machine. If the tap is open and you still see the error, there might be another problem.
Inspect the Hose: Next, look at the hose that brings water from your tap to the dishwasher. Check if the hose is bent or twisted. If it is, straighten it out. A bent hose can block the flow of water. Also, check for any blockages in the hose. Sometimes, debris or kinks in the hose can stop water from passing through. If the hose looks damaged, it might need to be replaced.
Clean the Filter: The filter in your dishwasher helps to catch food particles and other debris. If the filter is clogged, it can block water flow. Find the filter, which is usually at the bottom of the dishwasher. Remove it carefully and rinse it under running water. Use a brush or cloth to scrub away any stubborn particles. Once it’s clean, put the filter back in place.

Test the Water Pressure: If the above steps don’t fix the problem, check the water pressure. Low water pressure can cause E1 errors. To test this, turn on the tap and see if the water flows strongly. If the water flow seems weak, there might be an issue with your home’s plumbing. In this case, you might need a plumber to help.
Restart the Dishwasher: After checking everything, turn the dishwasher off and then back on. Sometimes, restarting the machine can reset the error code. If the error still appears, it might indicate a more serious issue, and you might need to call a professional repair person.

2. Error Code E2: Drainage Problem

What It Means: Error code E2 means your dishwasher is having trouble draining the water. This can lead to water sitting in the machine after a wash cycle.

What to Do:

Check the Drain Hose: Start by looking at the drain hose, which takes used water out of the dishwasher. Make sure the hose is not blocked or twisted. If the hose is bent or kinked, straighten it out. Check for any visible blockages. Sometimes, food or debris can get stuck in the hose and stop the water from draining properly.
Clean the Drain Pump: The drain pump helps remove water from the dishwasher. To access the pump, remove the bottom rack of the dishwasher and look for the pump cover. Take off the cover and look inside for any debris or objects that might be blocking it. Carefully remove any blockages. Be gentle to avoid damaging the pump.

Inspect the Sink Connection: The drain hose usually connects to your sink or garbage disposal. Check this connection for clogs. If you find any blockage, clear it out. Sometimes, food particles can clog the sink or disposal and prevent proper drainage.
Check the Float Switch: The float switch helps monitor the water level inside the dishwasher. If it’s stuck or blocked, it can cause drainage issues. Locate the float switch, which is usually at the bottom of the dishwasher. Make sure it moves freely. If it seems stuck, clean it and remove any debris around it.
Restart the Dishwasher: After completing these steps, turn off the dishwasher and then turn it back on. This can sometimes reset the error code. If the problem continues, it might be time to call a professional technician for help.

3. Error Code E3: Heating Problem

What It Means: Error code E3 means there is a problem with heating the water in your dishwasher. This can affect how well your dishes are cleaned.

What to Do:

Check the Heating Element: The heating element is usually located at the bottom of the dishwasher. It heats the water during the wash cycle. Look at the element for any visible signs of damage, such as cracks or breaks. If the element is damaged, it will need to be replaced.

Inspect the Thermostat: The thermostat helps regulate the water temperature. If it’s not working correctly, it can cause heating problems. Find the thermostat, which is often located near the heating element. Check if it seems faulty or if there is any visible damage. If needed, you might need to replace the thermostat.
Check Wiring Connections: Sometimes, heating issues can be caused by loose or damaged wiring. Inspect the wires connected to the heating element and thermostat. Make sure all connections are secure. If you see any frayed or damaged wires, they might need to be repaired or replaced.
Test the Dishwasher: After checking the heating element and thermostat, run a short cycle to see if the dishwasher heats the water correctly. Listen for any unusual noises, which might indicate a problem with the heating element.

Call a Professional: If the error persists after checking these components, it might be best to contact a professional repair person. Heating issues can sometimes be complex and require expert help.

4. Error Code E4: Overflow Issue

What It Means: Error code E4 indicates that there might be too much water inside the dishwasher. This can cause water to spill out or flood the machine.

What to Do:

Check for Leaks: First, look around the dishwasher for any signs of leaks or spills. Check the floor around the machine and inside the dishwasher. If you see water, there might be a leak or overflow issue.
Inspect the Float Switch: The float switch helps detect the water level inside the dishwasher. If it’s stuck or not working properly, it can cause an overflow error. Locate the float switch, usually at the bottom of the dishwasher. Make sure it moves up and down freely. Clean it if necessary, and remove any debris around it.
Check the Drain Pump: The drain pump helps remove excess water. If it’s not working correctly, it can cause an overflow. Remove the pump cover and check for any blockages. Clear out any debris you find.

Inspect the Door Seal: The door seal helps prevent leaks. If it’s damaged or not sealing properly, it can cause water to escape. Check the seal around the door for any signs of wear or damage. Replace the seal if needed.
Restart the Dishwasher: After checking these components, turn the dishwasher off and then back on. This can sometimes reset the error code. If the overflow issue continues, it’s a good idea to call a professional repair person for assistance.

5. Error Code E5: Sensor Error

What It Means: Error code E5 indicates that one of the sensors in your dishwasher is not working correctly. Sensors help the dishwasher understand different functions, like water temperature and cycle status.

What to Do:

Clean the Sensors: Sensors can sometimes get dirty or covered with grime. Locate the sensors inside the dishwasher, which are usually near the top or sides. Use a damp cloth to gently clean them. Be careful not to damage the sensors.
Check Wiring Connections: Loose or damaged wiring can affect sensor performance. Look at the wires connected to the sensors. Make sure all connections are secure. If you find any damaged wires, they might need to be repaired or replaced.

Inspect Sensor Functionality: If cleaning and checking connections don’t fix the problem, test the sensors. Some dishwashers have diagnostic modes that can help check if sensors are working properly. Refer to your dishwasher’s manual for instructions on how to use this feature.
Reset the Dishwasher: Turn off the dishwasher and then turn it back on. Sometimes, resetting the machine can help resolve sensor issues. Run a short cycle to see if the error code goes away.
Call a Professional: If the error code persists after trying these steps, it might be best to contact a professional technician. Sensor issues can be complex and may require expert help to fix.

6. Error Code E6: Motor Problem

What It Means: Error code E6 means there is a problem with the motor in your dishwasher. The motor helps run various parts of the machine, like the spray arms and pump.

What to Do:

Inspect the Motor: The motor is usually located at the bottom of the dishwasher. Look for any visible signs of damage, such as cracks or unusual wear. If you notice any issues, the motor might need to be replaced.

Listen for Noises: Turn on the dishwasher and listen carefully. If you hear unusual noises, like grinding or buzzing, it could be a sign that the motor is failing. These noises can indicate that the motor is not working properly.
Check Motor Wiring: Loose or damaged wiring can affect motor performance. Inspect the wires connected to the motor and make sure they are secure. If you find any damaged wires, they might need to be repaired or replaced.
Test the Motor: Some dishwashers have diagnostic modes to test the motor. Refer to your dishwasher’s manual for instructions on how to use this feature. Testing the motor can help determine if it’s working correctly.

Contact a Professional: If you’re unable to fix the motor issue yourself, it’s a good idea to call a professional repair person. Motor problems can be complex and often require expert help.

7. Error Code E7: Door Lock Issue

What It Means: Error code E7 means there is a problem with the door lock of your dishwasher. The door lock keeps the door securely closed during operation.

What to Do:

Check the Door Latch: Look at the door latch, which helps keep the door closed. Make sure it’s not blocked or damaged. If the latch is stuck, gently clean around it and ensure it moves freely.
Inspect the Lock Mechanism: The lock mechanism helps keep the door securely closed. Check if it’s working correctly. If the mechanism seems faulty or damaged, it might need to be replaced.
Clean the Door Seal: The door seal helps prevent leaks and ensures the door closes properly. Check the seal for any damage or debris. Clean the seal and replace it if it’s worn out.

Test the Door Lock: After checking the latch and lock mechanism, close the door and start a cycle. Make sure the door locks securely and the dishwasher operates normally. If the door doesn’t lock properly, the error code might still appear.
