Like all modern appliances, Bosch equipment displays error codes if something goes wrong, this makes troubleshooting and repairs much easier. These codes, sometimes known as fault codes are shown either as an alphanumeric digital display or through a sequence of LED lights. Fault codes vary according to the type of appliance and the model. While they give an indication of where the problem lies, each code covers a number of potential problems.
This article is for you if you:
Have a Bosch washing machine, dishwasher or induction hob which is displaying an error code
Want to know what are the most common faults for Bosch appliances
Have to describe an issue to an engineer so they know what replacement parts you may need
Bosch washing machine error codes
When interpreting Bosch washing machine fault codes you need to know both the code and the range your model falls into. Frustratingly, the same code on two different models could indicate a totally different problem. Listed below are some common Bosch washing machine error codes for popular models.
Bosch WAE range washing machines with digital displays
E16 – The door is not locked properly Open the machine, make sure there’s no clothing caught in the door and close it again. Press the start button. If this doesn’t work try turning the machine off and on again. If you still have an E16 code and the machine isn’t overloaded it’s time to call an engineer.
E18 – There is a problem with water supply or drainage Check the filter and drain pump and make sure there are no kinks in the water inlet hose. You may also need to clean the drain pump. You can find instructional videos on how to do this in various places on the internet including on the Bosch UK site. If you’re not confident to do the job yourself or simply don’t want to, you can book a local engineer for appliance repair through Fantastic Services.
E32 – Unbalanced load Another simple to fix problem, as it’s not a fault with the machine at all. This error code occurs at the end of a cycle when the load has become unbalanced and can’t be spun safely. Open the machine, redistribute the load and respin if required.
E23 – Leakage, or water in the base plate Since water and electricity make for an unhappy mixture this isn’t a problem you should try to fix yourself. Turn off the water supply tap, disconnect the appliance from the electricity supply and call an engineer.

E1- Water heating problem It’s likely that the heating element has failed and will need to be replaced.
E2 – Motor fault The motor isn’t turning. This could be due to either the motor control module or the motor itself being faulty. This code could also mean the carbon brushes need replacing.
E3 – Door not fully closed Try opening and closing the door, if this works you’re good to go. This fault code can also occur if there’s a problem with the latching mechanism or the door interlock.
E5 – The washing machine is not filling with water This could mean that the water supply valve is switched off, the inlet hose is kinked, or the water inlet valve has failed
E6 – The washing machine is slow to empty If your washing machine won’t drain properly, check for blockages or kinks in the drainage hose. The drainage pump may need cleaning or it could be faulty.
Bosch WFP Washing Machine Error Codes
Some of the most common problems that could trigger error codes on your Bosch washer are simple. The door mechanism might be faulty, the filter or drain pipe might be clogged, or you might need to level your washer to clear those codes out. Others could be complex, like shorted sensors, defective heating elements or problems with the washing machine motor. Unless you have experience in washing machine repairs, it is always advisable to contact a certified engineer to perform the repairs and save you time or even further damage to your appliance, property, or your health. You can use the following list as a reference for the the most common error codes that you may encounter with your Bosch WFP series washer:
F01 – Water intake timeout. Low water pressure
F02 – Heater element faulty or wiring issue.
F03 – Faulty or blocked pump
F04 – Faulty Motor
F05 – Faulty carbon brushes
F06 – Short circuit on NTC detected
F07 – Open circuit on NTC detected. Faulty NTC
F08 – Door is open when the program starts or door which fault.
F09 – Unexpected heating.
F10 – Communication error. This fault code normally requires the services of a qualified engineer.
F11 – Overheating heat sink or motor control PCB.
F12 – Short circuit or faulty motor.
F13 – Mains voltage too high.
F14 – Mains voltage too low
Bosch washing machine reset procedure
Sometimes, even when the fault is remedied the error code continues to display and the machine will not start. In this case, it needs a reset. Just as fault codes vary across models, so do Bosch washing machine reset protocols. The most common reset for Bosch washing machines is as follows:
Turn the program dial to the off position (12 o’clock)
Turn the dial to the 6 o’clock position
Press and hold down the spin button while turning the dial to he 7 o’clock position
Hold the spin button for around 5 seconds and then release
Turn the dial to the off position
It sometimes takes a few attempts for the machine to reset.
As with washing machines, Bosch dishwasher fault codes can vary across models. Also as with washing machines, Bosch dishwasher error codes indicate the type of problem, not the exact issue. Some error codes indicate a problem you can easily fix yourself, others are a sign that professional maintenance is required. Below is a Bosch dishwasher fault codes list for a few other common problems:
E01 / E02 – Temperature sensor or thermistor issue.
E03 – Dishwasher cannot fill water.
E04 – Water flow sensor issue.
E05 – Dishwasher overfilled.
E06 – Aqua sensor fault.
E09 – Heating element is defective It’s worth checking the salt sensor to make sure that this isn’t dirty and that the salt itself has been topped up. Assuming that there’s no problem with the salt it’s likely that the heating element needs repair or replacement.
E12 – Limescale build-up.
E14 – Flow meter failure.
E15 – indicates a leakage. You can check around the machine for visible leaks and check hoses for kinks or visible damage. You may feel confident to replace a hose yourself but anything more than this should be attended to by a qualified engineer.
E16 and E17 – Water filling the system or insufficient water level in the dishwasher.
E18 – Water flow into the dishwasher. Probable pump issue.
E19 – Heat exchanger fault Sadly this isn’t a problem with a simple fix, you’ll need to call an engineer.
E27 – Insufficient voltage in the electrical network Not a problem with the appliance itself. You probably need an electrician rather than an appliance engineer to resolve this issue.
Bosch induction hob error codes
Induction hobs offer fast, energy-efficient and flexible stove-top cooking but as with any appliance, they can develop faults. Understanding Bosch induction hob error codes will tell you what the problem is and can help you decide if you need appliance repair. If you do contact an engineer they’ll be able to help you more quickly if you tell them what error code you have.
F1/F6 – The unit has been switched off to protect the work surface from overheating Wait for everything to cool down before reusing the hob. The most common faults in induction hobs relate to overheating. Switching off in this situation is a normal safety feature and might happen if you’re using the hob intensively. If however the problem happens frequently or during light usage, it’s best to call an engineer to diagnose any underlying problems.
F2 – Electronics have overheated One of the hot plates will have been switched off. Wait for the unit to cool and try using it again.
F4 – The whole unit is overheated. The hob would switch off entirely, you’ll need to let it cool before trying to use it again.
F5– Hot cookware in the control panel area has overheated Remove the cookware from the panel area and give the unit time to cool down and autocorrect.
F5 – Hot cookware in the control panel area.
F8 – Hotplate has worked extensive time without stop.
E9000/ E90 10 – Supply voltage fault.
0400 – Hob not properly connected.
