Hi, Im Daniel and welcome to Just Answer. Sorry to hear you are having trouble with your washer, Hopefully i can help you on this.
You may get an offer for a phone request, Now im afraid i dont do them as i only do the online chat so if you dont want the phone request then just ignore it.
If its getting warm but not drying then its lost the airflow in there.
This can be either the dryer fan motor faulty or the dryer condenser chamber is blocked.
If you are looking at fixing yourself then you need to remove the top of the washer and there you will see the dryer chamber on top of the drum.
There is the dryer motor. Check this and carefully set the dryer going and see if the fan is running.
If not then turn the power off and remove the dryer chamber and check if theres anything jammed in the fan motor. If not and it stiff to turn then it needs to be replaced.
But if the dryer motor is fine then you need to remove the condenser and give this a good clean. This is the plastic chamber that runs from the bottom of the dryer chamber to the back of the drum.
Give this a good clean and then once clear refit it all and retry it and see how it goes from there.
Regards
