Recently, my dishwasher suddenly threw an E4 error, indicating a water leak, and I was in a total panic! The machine kept draining and wouldn’t work properly. Even worse, when I tried to restart it, the kitchen circuit breaker tripped, which was super frustrating. To help anyone facing the same issue, I’ve put together this simple repair guide, so let’s dive in!
Fault Symptoms
- Suddenly displayed E4 error, indicating a water leak.
- The machine kept draining, making it unusable.
- The kitchen circuit breaker tripped when I attempted to reset it, leaving me helpless.
After-Sales Service
I contacted customer service, and a technician came to check it out. They opened the bottom of the machine and found some water accumulation but couldn’t pinpoint the leak. Although they reassembled it and the error code disappeared temporarily, the problem returned quickly, which was exhausting.
DIY Repair Steps
If you want to give repairing the E4 leak error a shot, here are the steps to follow:
- Turn Off Water and Power: Before starting, ensure that you disconnect the water supply and power for safety!
- Remove the Bottom Cover:
- Locate the screws on the bottom of the machine and unscrew them with a screwdriver.
- Carefully pry off the surrounding clips to easily remove the bottom cover.
- Check the Leak Switch:
- Inside the bottom cover is a float switch that monitors the water level.
- If this switch is submerged in water, it may trigger the error message.
- Inspect the Drain Pump:
- Look at the seams of the drain pump to find potential leak sources.
- Leaks usually occur due to worn-out O-rings.
- Replace the O-Ring:
- Detach the drain pump, which usually has clips for removal.
- Purchase the appropriate size O-ring (like 60mm in diameter) from an online store and replace it.
- Reassemble:
- Put all the components back in order, ensuring every screw and clip is securely fastened.
Repair Results
After following these steps, the E4 leak issue was finally resolved! After some time of use, I’m thrilled to report that there have been no further leaks!
Other Considerations
- If you encounter other issues while using the dishwasher, such as water backflow from the sink into the dishwasher, consider replacing the drain outlet connector to ensure proper drainage.
