If your Bosch dishwasher is not filling with water, it can be frustrating and inconvenient. This problem may be caused by a range of issues, from water supply problems to a faulty inlet valve.
In this article, we will walk you through the common reasons and solutions for when your Bosch dishwasher isn’t filling, so you can get your dishwasher working again.
Water Supply Issues
The first thing to check when your Bosch dishwasher is not filling with water is the water supply. Ensure that the water supply is turned on and there are no blockages in the water line. If your dishwasher is not connected to a steady water source, it won’t fill with water.
- Check the water supply valve under your sink to make sure it’s fully open.
- Ensure there are no kinks or blockages in the hose leading to the dishwasher.
If there are low water pressure issues from your home’s plumbing, this may also prevent the dishwasher from filling. In such cases, you may need to contact a plumber to fix the pressure problem.
Inspect the Inlet Hose for Kinks or Blockages
Another common cause is a kinked or blocked hose. The hose that supplies water to your dishwasher can become kinked, bent, or clogged over time, which restricts water flow.
- Inspect the water inlet hose behind the dishwasher for any visible damage or bends.
- If necessary, replace the hose to ensure proper water flow.
Low water flow or a blocked hose may also result in your Bosch dishwasher not filling with enough water, causing incomplete cleaning cycles.
Water Inlet Valve Issues
The water inlet valve is responsible for controlling the flow of water into your dishwasher. If the valve is faulty, your dishwasher won’t fill with water. Here’s how to test the water inlet valve:
- Locate the water inlet valve (usually near the bottom front of the dishwasher).
- Using a multimeter, test the valve for continuity. If it fails the test, you will need to replace it.
A malfunctioning inlet valve could also cause a situation where the Bosch dishwasher hums but no water enters. In this case, the dishwasher is trying to run, but it isn’t receiving any water.
Check the Float Assembly and Switch
The float assembly is a small device that monitors the water level inside the dishwasher. If the float switch is stuck or broken, it can prevent the dishwasher from filling with water. To troubleshoot:
- Open the dishwasher door and locate the float (a small, dome-shaped device near the front).
- Move the float up and down to check for proper movement. If it’s stuck or malfunctioning, the Bosch dishwasher float switch may need replacing.
The float switch could be the reason for your Bosch dishwasher not filling with water but no error code is displayed. If the dishwasher isn’t filling yet there’s no error on the display, the float assembly is a likely culprit.
The Door Switch Might Be Malfunctioning
Your Bosch dishwasher won’t fill with water if the door switch is malfunctioning. The door switch ensures that the door is properly closed and sealed before allowing water to enter the unit.
- Check if the door is properly closed and if the latch engages correctly.
- If the door switch is faulty, it will need to be replaced to restore normal function.
Filter Blockages
Blockages in the dishwasher’s filter can also prevent water from flowing properly. A clogged filter may result in incomplete water filling, or even a Bosch dishwasher filling with water but not spraying.
- Remove the filter located at the bottom of the dishwasher and clean it thoroughly.
- Ensure that no food debris or residue is blocking water flow through the system.
When to Call a Professional
In some cases, you may need professional help, especially if you’ve checked all the common causes and your Bosch dishwasher is still not filling with water. For older models like the Bosch Classixx dishwasher or Bosch Eco sense dishwasher, a professional may need to inspect the internal components such as the water inlet valve or float switch.
If you’ve recently purchased a new Bosch dishwasher, and it’s already experiencing issues with filling, you may be able to contact Bosch support for warranty repairs.
Conclusion:
When your Bosch dishwasher isn’t filling with water, it’s important to systematically check the water supply, inlet hose, float assembly, and water inlet valve to identify the problem. By following the steps outlined above, you can resolve the issue and get your dishwasher working properly again. If none of these steps work, it may be time to call a professional for help.
