Common Causes Of E305 Error
The Bosch oven error code E305 often points to specific internal problems. Understanding the common causes helps in fixing the issue quickly. This error usually relates to the oven’s temperature sensor, wiring, or control board.
Each part plays a vital role in the oven’s operation. A fault in any can trigger the E305 error. Let’s explore the main reasons behind this code.
Sensor Malfunction
The temperature sensor checks the oven’s heat level. If the sensor fails, the oven cannot read the temperature correctly. This failure causes the E305 error code to appear. Sensors can break due to wear or damage. A faulty sensor needs replacement to restore proper function.
Wiring Issues
Wiring connects the sensor to the control board. Loose or damaged wires disrupt the signal. This disruption leads to the error code E305. Wires can wear out or break over time. Checking wiring connections and repairing any faults can solve the problem.
Control Board Problems
The control board manages all oven functions. If it malfunctions, it may misread the sensor data. This misreading triggers the E305 error. Control boards can fail due to electrical faults or age. Repair or replacement of the board often fixes the error.
Basic Troubleshooting Steps
Basic troubleshooting steps can help fix the Bosch oven error code E305. These steps are simple and do not need special tools. Try them before calling a technician. They often solve the problem quickly.
Power Reset
Start by turning off the oven power. Unplug the oven or switch off the circuit breaker. Wait for about one minute. This allows the oven to reset its internal system. Then, turn the power back on. Check if the error code is gone.
Check Door Closure
Open and close the oven door firmly. The door must be fully closed for the oven to work. Look for any dirt or debris on the door seal. Clean the seal gently with a cloth if needed. A door that does not close well can cause the E305 error.
Inspect Oven Sensor
Locate the oven sensor inside the oven cavity. It looks like a small metal rod. Make sure it is not touching the oven walls. A bent or damaged sensor can cause false error codes. If you see damage, contact a professional for repair.
Replacing The Oven Sensor
Replacing the oven sensor is a common fix for Bosch Oven Error Code E305. The sensor checks the oven’s temperature and sends this info to the control board. A faulty sensor causes wrong readings and errors. Swapping out the sensor can solve this problem and restore normal oven function.
This task is doable with basic tools and some care. Understanding your sensor type helps to pick the right replacement part. Follow the steps carefully to avoid damage and ensure safety.
Identifying The Sensor Type
Bosch ovens use two main sensor types: thermistor and thermocouple. The thermistor is a small, thin probe inside the oven cavity. The thermocouple looks like a small metal rod near the burner. Check your oven manual or look inside the oven to find which sensor you have. Using the correct sensor ensures the new part works correctly.
Tools Needed
- Phillips screwdriver
- Flathead screwdriver
- Multimeter (for testing the sensor)
- Replacement oven sensor
- Needle-nose pliers
- Protective gloves
Step-by-step Replacement Guide
- Unplug the oven or turn off power from the circuit breaker.
- Open the oven door and remove racks for easy access.
- Locate the sensor inside the oven cavity, usually at the back wall.
- Remove screws holding the sensor in place using a Phillips screwdriver.
- Gently pull the sensor out to access the wire connector.
- Disconnect the sensor wires carefully, noting their position.
- Attach wires to the new sensor in the same order.
- Secure the new sensor with screws in the original position.
- Replace oven racks and restore power to the oven.
- Test the oven to ensure the error code is gone and temperature reads correctly.

Fixing Wiring And Connection Issues
Fixing wiring and connection issues is key to solving Bosch oven error code E305. This code often points to problems in the oven’s electrical system. Checking wires and connections can stop errors and keep the oven working well. Simple steps can reveal and fix common wiring troubles safely.
Locating Wiring Problems
First, unplug the oven to avoid electric shock. Open the back panel to access the wires. Look for burnt or broken wires. Check if any wires are loose or disconnected. Use a flashlight to see small details. A multimeter helps test if wires carry power. Mark any damaged wires for repair or replacement.
Repairing Loose Connections
Loose connections cause error codes like E305. Tighten screws on wire terminals with a screwdriver. Push wires firmly into their slots. Cut and strip wire ends if damaged. Use wire nuts or connectors to join wires securely. Avoid using tape alone as it can fail. Reassemble the panel once all connections are tight.
When To Call A Professional
Do not continue if unsure about wiring work. Complex electrical faults need expert tools and skills. Calling a certified technician prevents damage and injury. Professionals find hidden wiring problems fast. They ensure repairs meet safety standards. Trust experts for lasting solutions and peace of mind.
Control Board Troubleshooting
The control board is the brain of your Bosch oven. It manages all functions and settings. Troubleshooting this part can fix the E305 error code. This section explains how to identify problems and possible solutions.
Signs Of Control Board Failure
Oven buttons stop working or respond slowly. The display may flicker or show strange codes. Oven cycles may start but not finish. Heating elements might not turn on. These are clear signs the control board could be faulty.
Resetting The Control Board
Resetting can clear minor glitches. First, unplug the oven from power. Wait for 5 minutes to let the board reset. Plug the oven back in and turn it on. Check if the error code disappears. This simple step can solve many control board issues.
Replacing The Control Board
Replacement is needed if resetting fails. Always disconnect power before starting. Remove the oven’s back panel to access the board. Carefully unplug all connectors from the old board. Install the new control board and reconnect cables. Secure the panel and restore power. Test the oven to ensure it works properly.
