Siemens WFF2000 Washing Machine Fault Codes

There are a number of different version of the electronics used in Bosch Group made washing machines and washer dryers that are sold under the Bosch, Neff and Siemens and some of them use the same fault or error codes when they have a problem or a spare part fails.

This is one of the common sets of fault codes for Siemens washing machine models as well as other Bosch Group produced brands. Do note that these fault codes for the Siemens WFF washing machines are different from the Bosch WFF Range error codes.

These fault codes are displayed by way of a lit, blinking or flashing light on the front of the washing machine. If it is the latter then you will see a pattern to the flashes if you look closely it will be a series of rapid flashes followed by a pause and then the series of flashes will be repeated, this is the error code being displayed. If you count the number of flashes being given then you use that number to correspond to the fault code, for example, three flashes would be fault code 3.

Before you start any investigation of the fault or even remove the lid of the washing machine please read and fully understand this article in full and pay particular attention to the safety and information notices at the bottom of this page as they contain extremely important information!

Siemens WFF2000 Washing Machine Fault Codes

These fault codes are written for washing machine repairers and not for the general public by Bosch Siemens and UK Whitegoods and they assume a certain level of competence on the part of the user in diagnostic routines. We have added some notes to try to assist you in determining the nature of the fault you have but, you will still need to investigate each failure on its own merits.

For more help and advice on fault finding on a washing machine please refer to our washing machine fault finding guide from this link before you begin.

Please check that any Siemens washing machine spares recommended are suitable for use on your particular model and ENR code. If you are unsure about the suitability of any spare part please ask to ensure that you get the correct spares for your washing machine. Please, don't guess or assume as spares can be altered on a production run with the same model number having several different alternative components used.

These fault codes for the Siemens WFF Range of washing machines are very similar to the fault codes for other Bosch produced washing machines and a lot of the spare parts are common to both ranges as well. These error code however do not apply to the Bosch range of machines as they use a different set of fault codes.

Fault Code Lights Legend

This is our very simple legend to show the state of the lights, lamps or LED's as they are unlit, flashing or lit continuously.

Siemens Washing Machine Fault Codes

The LEDs in these error codes represent the spin, rinse and then wash LED's as you look at them, being either lit or not lit, they should not be flashing.

Fault Code 1

LED or light lit constantly, not flashing

LED or light not lit

LED or light not lit

Door open after program has been started

This error code may well not show up for a minute or so after you actually go to start the washing machine but the door can be closed and the program restarted.

If the error persists there may be a fault with the door locking mechanism or door latch. 

Fault Code 2

LED or light not lit

LED or light lit constantly, not flashing

LED or light not lit

Water intake has failed
Error after more than 10 minutes

Generally speaking this will be a failure of the water inlet valve or the water supply itself has been cut off somehow. This can be due to the water valve or supply as stated but it may also be worth checking the filters in the fill valves to ensure that they are clear.

The machine should halt after about five minutes and drain down any water in it but it can be restarted.

Fault Code 3

LED or light lit constantly, not flashing

LED or light lit constantly, not flashing

LED or light not lit

Heating time exceeds 105 minutes

This would ordinarily indicate a fault with the water heating element or, certainly, the water heating circuit as the washing machine is indicating that it has failed to reach temperature. 

The error can be caused by faulty wiring, the heater as stated, low voltage or even a calcified heater has been known to generate this error code.

Fault Code 4

LED or light not lit

LED or light not lit

LED or light lit constantly, not flashing

Takes longer than 6 minutes to drain.

Very often you will see this error if the filter is blocked or obstructed or the drain pump is jammed or faulty. 

This error code can also be caused by the pressure sensor being blocked, a much discussed topic in the forums, by overfoaming from overdosing detergent or using a poor quality detergent as well as a pressure switch or sensor failure.

When this error occurs the program is aborted as it is considered to be a "fatal error" without any attempt to drain the washing machine.

Fault Code 5

LED or light lit constantly, not flashing

LED or light not lit

LED or light lit constantly, not flashing

Fault detected in motor or drive circuit

Very often you will see this error if the carbon brushes (link for the Genuine Bosch Spares set, this is the link to the cheap set) or the motor fails.

This error code can be generated by no tacho reading from the motor (the electronics cannot see the tach generator of the motor), a triac fault or short circuit or a faulty reversing relay on the control board. The washing machine will try to start the motor but after several attempts the program will be aborted with this error code which is again consider to be a "fatal error"

Fault Code 6

LED or light not lit

LED or light lit constantly, not flashing

LED or light lit constantly, not flashing

Unexpected heating

This is a bit of an odd error code and not a common one to see, it indicates that the washing machine has attempted to heat at a stage in the program where it should not. 

Fault Code 7

LED or light lit constantly, not flashing

LED or light lit constantly, not flashing

LED or light lit constantly, not flashing

NTC thermistor open circuit or short circuit
