A Bosch dishwasher is a vital appliance in any home, especially for those with a large family. It makes meals easier by washing the dishes efficiently. But, when the dishwasher starts flashing the E18 error code, it can be a cause of frustration. The E18 error usually means low water or a flow issue. This may be due to a clogged filter, drain line, or a pump failure. This guide will show you how to fix the E18 error on your Bosch dishwasher.
Understanding the E18 Error Code
The E18 error code appears when there is an issue with the water flow into the dishwasher. The water level might be too low, or the water pump might not be functioning correctly. The cause could vary from a simple clogged filter to a more severe pump failure. Understanding the cause of the E18 error is the first step in fixing the problem.
Step 1: Check the water supply
Before troubleshooting, disconnect the dishwasher from the mains for safety. Start by checking the water supply to the dishwasher:
- Ensure the water inlet valve is fully open and not restricted. Sometimes, the water may not flow into the machine due to a partially closed valve.
- Check that the hose to the dishwasher is not bent or kinked. This could restrict water flow.
Step 2: Inspect the drain and filter.
A common cause of the E18 error is a clogged drain or filter.
- Remove the dishwasher filter and check for any blockages. If you find any debris, clean it out thoroughly.
- Inspect the drain line for any clogs or kinks that might be restricting the flow. A clogged drain line can trigger the E18 error by blocking drainage.
Step 3: Test the Water Level Sensor
If the water level in the dishwasher is too low, it might say an issue with the water level sensor.
- Using a multimeter, test the sensor to ensure it’s functioning correctly. If the sensor is faulty, it could be providing inaccurate readings, causing the E18 error.
- If the water levels do not rise, it might be due to a malfunctioning sensor or an obstruction in the inlet valve.
Step 4: Examine the pump.
A malfunctioning pump can also lead to the E18 error code.
- If the water pump is not functioning correctly, there might be a failure in the pump itself. Check if the pump is making any unusual noises or not working at all.
- If the pump can’t move water through the dishwasher, it may need replacement.
Step 5: Final Checks and Test Run
After the checks, reconnect the dishwasher to the mains. Then, run a short cycle to see if the E18 error is fixed.
- Check the water levels and ensure they rise to the appropriate level for a wash cycle.
- Check for signs of clogged filters, drain line blockages, or pump issues during the cycle.
If all works well, your Bosch dishwasher should now run without the E18 error code.
Additional Tips
To avoid the E18 error, check filters and drain lines for clogs. Ensure that the water supply remains unrestricted and maintains a consistent water level. This will keep your dishwasher running well. It will save you from washing dishes by hand and ensure it works well at meal times.
