These codes aren’t universal across all Bosch models; variations exist, so consulting your appliance’s manual is crucial for accurate interpretation.
Error codes aren’t merely labels; they pinpoint the affected system within the washing machine. A code related to water supply (like E11 or E12) directs your focus to the inlet hose and water pressure. Conversely, a drainage-related code (E03 or E17) suggests investigating the drain hose and pump. Recognizing this correlation streamlines the troubleshooting process, allowing you to efficiently isolate the problem. Many newer models also display a brief descriptive message alongside the code, enhancing clarity for the user.
Common Bosch Washing Machine Problems
Beyond specific error codes, several recurring issues plague Bosch washing machines. Drainage problems are frequent, often stemming from clogged drain hoses or pump filters. Insufficient water supply, indicated by codes like E11, can result from a kinked inlet hose or low water pressure. Door-related errors (E16/F16) frequently occur due to improper door closure or a faulty door latch mechanism.
Furthermore, heating element failures manifest as water not heating during the wash cycle (E02). Motor issues, though less common, can lead to the machine failing to spin or agitate. Electrical faults, while potentially dangerous, are often signaled by specific error codes. Regularly cleaning the detergent dispenser and drum also prevents build-up that can cause operational issues. Addressing these common problems proactively extends the lifespan of your Bosch washing machine.
Decoding Bosch Error Codes: General Issues
Bosch error codes offer crucial diagnostic insights. These codes pinpoint the source of malfunctions, ranging from water supply and drainage to door lock and heating element failures.
Error Code E01: Door Open
The Bosch washing machine displays error code E01, or sometimes F01, when the door isn’t securely closed before the wash cycle begins. This is a safety feature preventing water leakage and ensuring proper operation. First, firmly close the door, ensuring it latches correctly. If the error persists, inspect the door seal for any obstructions like clothing or debris that might prevent a tight seal.
Additionally, check the door lock mechanism itself. A faulty door lock switch can falsely report the door as open, even when it’s closed. This requires a more in-depth inspection, potentially involving multimeter testing to verify the switch’s functionality. In some cases, a damaged door handle or latch can also contribute to this issue. If you’ve checked these components and the error remains, professional repair might be necessary to replace the door lock assembly.
Error Code E02: Water Not Heating
The Bosch washing machine error code E02 indicates a problem with the water heating element. This means the water isn’t reaching the required temperature for effective cleaning. Initially, verify the water supply is hot enough; a cold incoming water supply can mimic this error. If the hot water is sufficient, the issue likely lies within the machine itself.
Inspect the heating element for damage or failure. A faulty heating element is a common cause. Also, check the temperature sensor, as a malfunctioning sensor might incorrectly report the water temperature. A damaged wiring connection to the heating element or sensor can also trigger this error. Testing these components with a multimeter is crucial for accurate diagnosis. If you’re uncomfortable with electrical testing, contacting a qualified technician is recommended for safe and effective repair.
Error Code E03: Drainage Problem
The Bosch washing machine error code E03 signals an issue with the draining process. This indicates the machine isn’t effectively removing water after the wash cycle. A primary suspect is a blockage within the drain hose, preventing water from flowing freely. Carefully inspect the hose for kinks or obstructions.
Furthermore, the drain pump itself could be faulty or jammed. Debris like lint, small objects, or even socks can obstruct the pump impeller. Accessing and cleaning the pump filter is a crucial step in resolving this issue. If the pump appears functional and the hose is clear, a problem with the pressure switch, which detects water levels, might be the cause. Professional assistance may be needed to diagnose and repair more complex drainage system failures.
Specific Bosch Error Codes & Solutions
Decoding specific error codes unlocks targeted solutions for your Bosch washing machine. This section details common codes like E16, E17, and E18, offering practical fixes.

This is a safety feature preventing water leakage and ensuring proper drum rotation. Before panicking, visually inspect the door to confirm it’s securely latched. Sometimes, clothing can obstruct the door’s complete closure, so redistribute the load.
If the door appears closed but the error persists, check for any physical damage to the door latch mechanism itself. A broken or misaligned latch won’t register a secure closure. Gently try to close the door with a bit more force – avoid excessive force, as this could cause further damage. If the problem continues, the door lock/latch assembly may need replacement by a qualified technician. Ignoring this error can prevent the machine from running and potentially lead to more significant issues.
Error Code E17 / F17: Pump Issues ‒ Drainage Time Exceeded
The E17 or F17 error code indicates a problem with the washing machine’s drainage system. Specifically, the pump isn’t effectively removing water within the expected timeframe. This often points to a blockage somewhere in the drainage pathway. Begin by checking the drain hose for kinks or obstructions – ensure it isn’t bent or crushed. Next, locate and carefully clean the pump filter; this frequently traps lint, small objects, and debris.
If the filter is clear and the hose is unobstructed, the issue might be a failing drain pump itself. A worn or damaged pump may struggle to generate sufficient suction. In such cases, professional repair or pump replacement is necessary. Before calling a technician, verify the water supply is off and attempt a manual drain if possible. Ignoring this error can lead to water damage and further complications.
Error Code E18 / F18: Water Level Issues
The E18 or F18 error code signals a problem with the water level detection within your Bosch washing machine. This means the machine isn’t accurately sensing the amount of water inside the drum. Potential causes range from a faulty pressure switch – the component responsible for measuring water level – to obstructions in the pressure hose connecting it to the tub. Inspect the hose for kinks, blockages, or damage.
Additionally, a malfunctioning water level sensor or a problem with the control module itself could trigger this error. Carefully examine the sensor for any visible damage. If the issue persists after checking the hose and sensor, professional diagnosis and repair are recommended, as it may involve more complex internal components. Ignoring this error can lead to overfilling or insufficient water for proper washing.
Error Code E11 / E12 / F29: Water Supply Problems
Encountering error codes E11, E12, or F29 on your Bosch washing machine indicates an issue with the water supply. This commonly means the machine isn’t receiving enough water to begin or continue the wash cycle. The first step is to verify that both the water supply valve are fully open. Next, check the water inlet hose for any kinks or obstructions that might be restricting water flow.
Furthermore, a clogged water filter within the inlet valve can also cause this error. Locate and clean the filter to ensure unrestricted water passage. If water pressure is low, attempt to fill a bucket within a minute to assess the supply. If the problem persists, the inlet valve itself may be faulty and require replacement. Professional assistance is advised for valve replacement and complex water supply diagnoses.
Troubleshooting Water Related Issues
Addressing water-related problems involves inspecting the inlet hose, diligently cleaning the water filter, and accurately diagnosing water pressure to ensure optimal performance.
Checking the Water Inlet Hose
Begin by visually inspecting the water inlet hose for any kinks, bends, or obvious signs of damage, such as cracks or bulges. A kinked hose restricts water flow, leading to insufficient filling or prolonged cycle times. Ensure the hose isn’t pinched behind the washing machine or other objects.
Next, verify that both ends of the hose are securely connected – to the washing machine and the water supply valve; Loose connections can cause leaks and prevent proper water intake. Tighten the connections by hand; avoid using tools that could overtighten and damage the fittings.
Crucially, check the water supply valve itself to confirm it’s fully open. A partially closed valve will restrict water flow. Finally, disconnect the hose and briefly open the water supply valve to flush out any potential sediment or debris that may have accumulated inside the hose, potentially blocking water passage.
Cleaning the Water Filter
Locate the water filter, typically found behind a small access panel at the front, bottom of your Bosch washing machine. Before opening the panel, place towels around the area to absorb any spilled water. Have a shallow container ready to catch the remaining water in the filter housing.
Carefully unscrew the filter cap, turning it counterclockwise. Be prepared for water to flow out. Once removed, thoroughly clean the filter under running water, removing any lint, debris, coins, or other obstructions. Inspect the filter for damage and replace it if necessary.
After cleaning, check the filter housing for any remaining debris and remove it. Reinstall the filter, ensuring it’s securely tightened clockwise. Close the access panel. Running an empty rinse cycle can help flush out any remaining loose particles and confirm proper filter function.
Diagnosing Water Pressure
Insufficient water pressure is a frequent cause of Bosch washing machine issues, often manifesting as slow filling or an inability to start a cycle. Begin by verifying that both the hot and cold water supply valves are fully open. Next, disconnect the inlet hose from the washing machine and check the water flow rate by directing it into a bucket.
Ideally, the bucket should fill within one minute. If the flow is significantly slower, the problem lies with your home’s water supply, not the machine itself. Check for kinks or obstructions in the water supply hoses. Consider if other appliances are simultaneously using water, potentially reducing pressure.
If the water pressure seems adequate at the hose connection, the issue might be a partially blocked inlet valve within the washing machine. Professional inspection may be required to address this internal component.
Addressing Drainage Problems
Effective drainage is crucial for a functional washing machine; blockages or pump failures can cause issues. Regularly inspecting and maintaining the drain system is essential.
Checking the Drain Hose for Blockages
A common cause of drainage problems is a blocked drain hose. Begin by disconnecting the hose from both the washing machine and the drainpipe. Visually inspect the entire length of the hose for any kinks, bends, or obvious obstructions like lint, small articles of clothing, or debris. Gently flex the hose to help dislodge any trapped items.
Next, flush the hose with water, using a garden hose or a utility sink. Observe the water flow to identify any areas where the water is restricted. If a blockage is present, carefully use a long, flexible brush or a plumbing snake to clear it. Avoid using sharp objects that could damage the hose.
Ensure the drainpipe itself isn’t clogged. A partially blocked drainpipe can create backpressure, hindering the washing machine’s ability to drain properly. Once the hose is clear, reconnect it securely, ensuring a tight fit to prevent leaks during operation.
Inspecting the Drain Pump
If the drain hose is clear, the issue might lie with the drain pump itself. Caution: Disconnect the washing machine from the power supply before attempting any inspection. Locate the drain pump – typically accessible from a panel at the front or rear of the machine. Once accessed, carefully inspect the pump impeller for obstructions like coins, buttons, or hairpins.
Manually rotate the impeller to ensure it spins freely. If it’s jammed, gently remove any visible obstructions. Check the pump’s inlet and outlet for blockages as well. Listen for any unusual noises when manually turning the impeller, which could indicate bearing failure.
If the pump appears undamaged but isn’t functioning, it may be electrically faulty and require replacement. Testing the pump with a multimeter can confirm this, but should be done by a qualified technician.
Cleaning the Pump Filter
A clogged pump filter is a frequent cause of drainage problems in Bosch washing machines. Important: Have a shallow container and towels ready, as water will spill during this process. Locate the pump filter access panel, usually at the bottom front of the machine. Carefully open the panel and unscrew the filter cap – turn it slowly to control the water flow.
Remove the filter and thoroughly clean it, removing lint, hair, coins, and any other debris. Inspect the filter housing within the machine for any obstructions and clear them out. Ensure the filter’s rubber seal is intact and clean before reinserting it.
Securely tighten the filter cap, ensuring it’s properly sealed to prevent leaks. Finally, close the access panel. Regular filter cleaning – every few months – prevents future drainage issues.
Electrical & Other Common Errors
Beyond water and drainage, Bosch washers can exhibit electrical faults or unusual issues. These often manifest as specific error codes requiring careful diagnosis and potentially, professional assistance.

For instance, codes suggesting motor overload often point to obstructions or excessive laundry loads.
Other potential causes include worn carbon brushes (in some models), a failing motor capacitor, or a defective motor control module. Diagnosing these problems often requires a multimeter to check for continuity and voltage. If the motor isn’t receiving power, investigate the wiring harness and connections. A completely failed motor usually necessitates replacement, which is best left to a qualified technician due to the complexity of the repair and potential safety hazards. Always disconnect the power before attempting any electrical inspection or repair.
Error Codes Related to the Heating Element
When Bosch washing machines display error codes linked to the heating element, it usually signifies a problem with the water heating process. This could stem from a faulty heating element itself, a defective temperature sensor (NTC), or a malfunctioning relay on the control board responsible for powering the element. Error codes like E02 frequently indicate this issue.
Troubleshooting involves checking the heating element for continuity using a multimeter – a lack of continuity confirms a burned-out element. The temperature sensor should also be tested for accurate resistance readings. A faulty relay can be identified by checking for proper voltage delivery to the heating element when it should be active. Replacing a heating element or sensor is relatively straightforward, but always disconnect power first. If the control board is suspected, professional diagnosis and repair are recommended due to its complexity.
Resetting Your Bosch Washing Machine
Sometimes, a simple reset can resolve minor glitches within your Bosch washing machine’s control system. This process doesn’t erase program settings but clears temporary errors that might be causing unexpected behavior or error code displays. The most common method involves a “power cycle” – completely disconnecting the washing machine from the power outlet for a period of five to ten minutes.
Alternatively, some Bosch models support a factory reset through a specific button combination, often involving holding the ‘Start/Pause’ and another button simultaneously while powering on the machine. Consult your user manual for the precise procedure for your model. After resetting, re-establish the water supply and power connection, then attempt a short test cycle to verify functionality.
