Don’t worry—you’re not alone, and this is a common problem that many people face. The good news is that there are often simple DIY solutions to get your washing machine back in working order.
One frequent cause of the E37 error is a malfunctioning water inlet valve, which can lead to too much water entering the machine.
To help you understand this error more fully, I encourage you to read through the entire post. We’ll cover this cause and several others, providing you with the knowledge you need to tackle the issue effectively.
Let’s dive in!
What Does the Error Code Means?
When your Bosch washing machine shows the error code E37, it signals a problem with the water supply. This issue typically occurs when the water level goes beyond what the machine is designed to handle, which can pose safety risks. Your washing machine is fitted with sensors that continuously monitor the water level to ensure it operates within safe limits. If these sensors detect that the machine is overfilled, the E37 code will be triggered, acting as a safeguard against potential damage or leaks. It’s important to address this error without delay, as leaving it unattended can lead to more serious complications down the line. To keep your washing machine functioning optimally and safely, regularly inspect your water supply connections, hoses, and filters for any signs of wear or blockages. By staying proactive and attentive to these components, you can help ensure that your Bosch washing machine operates efficiently and safely for years to come. Additionally, regular inspections of the temperature sensor can prevent issues related to overheating and enhance the overall performance of your appliance. If you’re uncertain about any part of the process, don’t hesitate to reach out for professional assistance.
Common Causes Behind Error Code
Identifying E37 Error Code Causes
The E37 error code in Bosch washing machines is typically related to an overfilling issue, which can stem from several factors. A malfunctioning temperature sensor may lead to incorrect readings, causing the machine to fill excessively. Additionally, issues with the water inlet valve or a faulty pressure switch can contribute to this problem. Regular maintenance and timely troubleshooting are essential to ensure your washer operates efficiently.
Faulty Water Inlet Valve
A faulty water inlet valve is often a key player in the Bosch washing machine error code E37, which can be frustrating for users. This issue typically stems from either insufficient water pressure or a malfunctioning valve. Conducting a careful inspection of the valve can reveal whether it’s stuck in the open position or has sustained damage, both of which can lead to overfilling. Additionally, a consistent power supply is crucial for proper washer operation, as fluctuations can exacerbate issues like overfilling.
Here’s a quick breakdown of the common issues related to the water inlet valve, their symptoms, and potential solutions:
| Issue | Symptoms | Solution |
|---|---|---|
| Low water pressure | Slow fill rate | Check the water supply |
| Stuck open valve | Constant overfill | Replace or repair the valve |
| Damaged valve seal | Leaks during operation | Inspect and replace the seal |
Clogged Drain Hose
A clogged drain hose can lead to the Bosch washing machine error code E37, which may disrupt your laundry routine. When the drain hose is blocked, the machine is unable to expel water properly, resulting in overfilling. This issue can arise from a variety of factors, such as debris, lint accumulation, or foreign objects lodged within the hose.
To keep your washing machine in optimal condition, it’s important to routinely check the drain hose for any kinks or bends that could hinder water flow. If you do discover a blockage, the first step is to detach the hose from the machine. Give it a thorough clean, ensuring all obstructions are removed. A mixture of warm, soapy water can help dissolve any stubborn residues.
If you find that the issue persists even after cleaning the hose, it may be time to consider replacing it. A new drain hose can help restore your machine’s normal functionality and prevent any further complications. Addressing a clogged drain promptly is essential for maintaining the efficiency of your appliance and ensuring that your laundry routine runs smoothly. Always remember to disconnect the machine from the power supply before attempting any maintenance work for your safety. Additionally, if the problem continues, it may indicate a malfunctioning thermistor failure that requires further inspection.
Defective Pressure Switch
If your Bosch washing machine is showing the error code E37, it may be due to a defective pressure switch. This crucial component is responsible for monitoring water levels and ensuring that your appliance does not overfill. When the pressure switch malfunctions, it can mistakenly indicate that the water level is excessively high, triggering the error code.
Here’s a breakdown of common issues related to the pressure switch, their effects, and potential solutions:
| Cause | Effect | Solution |
|---|---|---|
| Blocked pressure tube | Inaccurate water level reading | Clear the blockage |
| Electrical failure | Pressure switch malfunction | Replace the switch |
| Wear and tear | Faulty pressure detection | Inspect and replace if necessary |
It’s essential to address a defective pressure switch promptly. Neglecting this issue can lead to more significant problems, affecting the overall performance of your washing machine. By understanding these common failure modes and solutions, you can take informed steps to restore your appliance to normal operation safely. If you’re unsure about any aspect of the repair, don’t hesitate to consult a professional technician for assistance. Your safety and the proper functioning of your appliance are paramount. Additionally, a malfunctioning door latch mechanism can also lead to operational issues in washing machines.
Faulty Float Switch
After addressing the potential issues with the pressure switch, it’s crucial to consider another key component that may trigger the E37 error code: the float switch. This device is responsible for monitoring the water level in your Bosch washing machine, ensuring that it doesn’t overfill. If the float switch is faulty, it can send incorrect signals to the control board, resulting in the E37 error code being displayed.
There are several common reasons why a float switch may fail. These include debris buildup, general wear and tear, or physical damage to the switch itself. To diagnose this issue effectively, start by inspecting the float for any blockages that could prevent it from moving freely. It’s important that the float can rise and fall without obstruction.
If you find that the float switch is compromised due to any of these issues, replacing it is essential. Doing so will help restore proper water level detection, thereby eliminating the E37 error code. Additionally, a breakdown in communication between the control board and other components can also contribute to this error. Always prioritize safety when working on your appliance, and if you’re uncertain, consider reaching out to a professional for assistance. Your washing machine will thank you for the attention it deserves!

Diagnose the Error Code
To diagnose the error code E37 on your Bosch washing machine, it’s important to approach the issue methodically to ensure your appliance operates safely and efficiently. This error typically points to a problem with the water inlet system. Here’s how to address it:
- Check the Water Supply and Pressure: Begin by verifying that your water supply is turned on and that there are no kinks or blockages in the hose. The water pressure should ideally fall within the manufacturer’s specified range. Low water pressure can lead to inaccurate readings and trigger the E37 error.
- Inspect the Water Inlet Valve: The next step is to examine the water inlet valve. This component can become blocked with debris or may malfunction entirely. Look for any signs of wear or damage, and ensure it’s operating correctly by listening for the sound of it opening and closing during a cycle.
- Sensor Calibration: If both the water supply and inlet valve appear to be functioning correctly, the issue may lie with the sensor calibration. An incorrectly calibrated sensor may mistakenly signal that the machine is overfilling, resulting in the E37 code. To test the sensor’s functionality, you might need to refer to the manufacturer’s instructions or consider consulting a professional if you’re unsure.
- Recalibration or Replacement: If you determine that the sensor is faulty, it may require recalibration or replacement. Always refer to your appliance’s user manual for specific instructions related to your model, and ensure you follow safety precautions when handling electrical components.
