When a dishwasher displays an E4 error code, it often means there is a water leakage problem or the appliance thinks there is. Some common causes include too much foam inside the machine, incorrect detergent usage, or a problem with the dishwasher’s parts. It could be a simple fix or require more steps.
Troubleshooting the issue can save time and money. Checking the dishwasher’s drain hose for bends or clogs is a good start. Cleaning the filter, making sure the dishwasher is level, and looking for loose parts can also help. If these steps do not fix the error, it may be time to consult the manual or get professional help.
It is important to remember to turn off the dishwasher before examining any parts. Safety should always come first. Simple steps can often get the dishwasher back up and running. If the problem persists, detailed error codes in the dishwasher’s manual or advice from a technician can guide further action.

Steps to Address an E4 Error
- Check the Water Supply: Make sure the water valve supplying your dishwasher is fully open. A partially closed valve can cause low water pressure.
- Examine Water Inlet Hose: Look for kinks, bends, or damage to the hose. A compromised hose can reduce water flow to the dishwasher.
- Clear the Float Switch: The float switch in your dishwasher helps monitor the water level. Sometimes it can stick, triggering the E4 code.
- Gently lift the float to see if it moves freely.
- Clean away any debris that may be obstructing it.
- Inspect Water Inlet Valve: Check the fine mesh screen on the water inlet valve. Clean away any buildup of grime or debris.
- Reset the Dishwasher: Sometimes, a simple reset can clear error codes.
- Turn off the power to your dishwasher at the breaker.
- Wait about 5 minutes for the system to reset.
- Restore power and try running a cycle again.
If the Issue Persists
If these steps don’t solve your E4 error code problem, it’s possible that you might have one of these more complex issues:
- Faulty water inlet valve
- Faulty control board
In these cases, it is best to call a qualified appliance technician for diagnosis and repair.
Diagnosing the E4 Error Code
When a dishwasher displays the E4 error, it indicates a specific issue. The steps to diagnose this include checking for blockages and inspecting water supply and drainage systems.
Understanding the Error
The E4 error on a dishwasher usually means there’s a water leak or overflow. This can happen if the dishwasher is tilted, the sensor might think there’s a leak. It’s important to make sure the dishwasher is level.
Checking for Blockages
A blocked drain hose or filter can cause the E4 error. Follow these steps to check:
Drain Hose
- Look for kinks or bends in the hose.
- Check for clogs. Remove any debris that might block water flow.
Filter
- Find the filter in the bottom of the dishwasher.
- Clean out any food or debris that might have built up.
Inspecting Water Supply and Drainage
Check these points for water supply and drainage:
- Inlet Valve: Confirm that the valve isn’t blocked and is supplying water.
- Drain Pump: Make sure it’s not clogged and is working well. If it’s not pumping out water, the dishwasher might show an E4 error.
- Kitchen Sink: Sometimes the sink can affect the dishwasher. If the sink drains slowly, fix that to help the dishwasher drain.
