Hi my name is***** will try and help you with your issue.
It sounds like there may be an issue with a sensor or motor, when you select a program even though it hums does the door lock as if it was starting the program?
Thank you for clarifying if its locking, its unlikely to be a sensor issue.
How old is the unit, and would you say its had allot of use over the years, if so it could be a drive belt or the motor brushes which are fairly cheap to have replaced, as they are consumables which are designed to be replaced every few years.
If you are willing and technically able I can talk you through the process of finding out the specific fault, organising a replacement part and fitting it yourself, you will need a set of screw drivers, and a multi meter.
If you do not want to do this your self, its time to get an engineer in, as this isnt a fix which is designed for consumers, or without taking the machine apart.
Firstly you need to unplug the machine, I am struggling to find a machine with that product number, what is the model number of the machine?
In the absence of the specific spec what your look to do is find the motor, most models have the motor located at the bottom so its best to place the unit on the side and you should be able to see right up inside.
With the unit unplugged you need to look for the drive belt which is attached to a large metal case (which is the motor. You should be able to pull the belt with you hand which will be stiff but should allow you to spin the drum, this proves its not the belt or anything mechanical.
If you cant find the motor send me a picture of what you see, once I have the model I can hopefully pull up the diagrams and explain how we can fault find the motor.
Right I cant find the engineering manual for this unit however have managed to find some diagrams. It appears the condenser is located at the bottom so it looks like we need to remove the rear panel as you wont be able to see up from the bottom.
The rear is made up of 4-5 parts, three small sections then the large panel. Use a screw driver to remove the rear compartments one part at a time, keep the screws safe and remember which ones go where. It may be useful to take a picture with your phone at each stage as you have to put them back in reverse order.
Once the back is removed you should be able to see the motor and manually move the drive shaft which should move the fan and also the drum.
Once you have the motor in sight take a multi meter and with extreme caution plug the unit in with the back removed set the program and use the multi meter to read the mains (230v) going to the two terminals on the motor. Make sure you do not touch any other metal parts when doing this, and once you have taken a reading, unplug the unit and leave for 5 minutes to fully discharge in order to reduce the risk of electric shock.
If you have a voltage reading and the motor is not moving you need to replace the brushes in the motor, if there is no voltage this would indicate some other electrical problem, which I am unable to talk you through troubleshooting remotely, due to limited documentation from the manufacturer.
To confirm you took the reading from the motor (which is the device which has the label in it, on the picture provided)?
This would suggest the motor brushes or motor itself has failed, next you need to try and trace where the red and blue wires go into the motor, they should go to two spade terminals, and remove wires from the spade terminals, and then look to see if you can see a small screw or hex bolt next to the spade terminal on the motor, the image I have for the motor makes it difficult to see, but it should be possible to do it without taking the motor out or removing parts of the motor.
Unscrew the spade terminal and a small cover should come away along with a black block about 1-2cm long (this is the carbon brush), it should have a spring attached be careful not to lose it. If the brush is longer than 2cm put it back, and do the same to the other terminal. If its less than 2cm you need to order a new set of motor brushes.
If the brushes are 2cm long or you cant see how to release the motor brushes, you need to look at replacing the motor, a replacement can be ordered here
I just wanted to see how you are progressing with replacing the motor on your dryer, if you require further assistance please let me know.
I would appreciate it if you could rate the assistance provided to date.
