When your Samsung dishwasher suddenly shows an error code like Error Code E07 / E15 / E40, it can be frustrating—especially if you’re in the middle of a busy day. These codes point to sensor errors, which can prevent your dishwasher from running properly. While some fixes are simple, others may require professional help. This guide will walk you through the possible causes, DIY troubleshooting steps, and when it’s best to call for a fast, local, same-day repair service.
What Do These Error Codes Mean?
Error Code E07: Usually indicates a problem with the water level sensor. This can happen if the sensor is dirty, clogged, or malfunctioning.
Error Code E15: Often related to a leak sensor detecting water where it shouldn’t be—possibly due to a small leak or moisture buildup inside the unit.
Error Code E40: Points to a temperature or turbidity sensor issue, meaning the dishwasher may not be able to measure water temperature or cleanliness properly.
These issues can affect the cleaning cycle and even stop your dishwasher from running altogether.
Quick Troubleshooting Steps
Before calling for emergency dishwasher repair, try these steps:
Restart the Dishwasher
Unplug the machine for 5 minutes, then plug it back in. Sometimes, this resets the sensor system.
Check for Blockages
Remove and clean the filter at the bottom of your dishwasher. Food debris and grease can trigger false sensor readings.
Inspect for Leaks (E15)
Look around the base of the dishwasher for any signs of water. Even a small puddle can set off the leak sensor.
Clean the Sensors (E07 / E40)
Carefully wipe the sensors inside the dishwasher using a soft cloth. Built-up detergent or limescale may interfere with readings.
Run a Maintenance Cycle
Use a dishwasher cleaner or vinegar cycle to clear mineral deposits.
If your dishwasher still shows the error code after these steps, it may require a part replacement or a more advanced repair.
