Hotpoint WDL540G washer/dryer fault

Hi All,
I am currently having issues with my hotpoint wdl540g washer/dryer. The missus put a wash on yesterday and as she put it, it appeared to get stuck at some point in the program but no fault lights appeared.
On return from work I noted water in the drum so I switched it off by holding the off button in for a while and then turning off at mains. This allowed me to clear the locked door switch, open the door and drain the water I could out of the drum. I then checked the pump pre chamber and it appeared clear. I also checked the water infeed line was clear and flow/ pressure into the machine from the mains was good.
I then tried to put it on a spin only program (B) and it appears the fault is hear somewhere. I can hear the motor attempt to spin the drum three times before having a break of about five minutes before then trying to do the same again. No fault lights appear and I am sure this cycle will continue unless I stop it by turning off. The belts are fine, no wear and tight enough, it appears that that the drive wheel from the motor is not moving/getting a signal to move.
Any ideas/help appreciated.

Check the motor brushes. Poss worn

Brushes changed and that issue is now sorted, washing fine. Only other slight issue is that I do still get some fault lights up occasionally when drying only. I had issues with the same fault before the problems with the brushes and thought it had been cured as it ran through the drying only program fine when doing once. However the missus put on one drying only cycle on straight after a previous drying only cycle and this problem is re-occurring.
Fault lights are all flashing along the bottom and the spin and dry lights are solid (not flashing) orange. Door lock light is solid red.
Any help on this fault code appreciated. Is it an overheating issue?
Cheers

You got error f13. Check the dryer is getting hot. Check the 2 small thermistor wires on the side of the heater box at the front. Also remove the heater box and use the cold supply hose to flush out the condenser it gets blocked with fluff and the small hose on the back is not powerful to flush the fluff out.
