My hotpoint ultima washer dryer has stopped drying, it goes through the programme but clothes are still wet at the end, no error codes are showing.

My hot point ultima wd860 does not dry any more the dryer only puts out cold air not hot why

Do u want to resolve the f-13 fault code ON HOTPOINT WD860 Ultima
Fix the fault . It is a tricky job but the heater thermostat switch has tripped as it senses something burning. Probably a little bit of fluff on the heater element inside the heater unit.. There are 2 switches on top of this heater unit. One where the 2 blue wires go on the top left of the 3rd picture and the other which has a tall black wire connector on shown in the middle of the 3rd picture. Remove that connector and undo the holding screw . You can then reset the switch. The switch is a small circular switch hidden beneather the connector on the photos. This thermostat switch has a yellow. red dot ontop of it. If you use a small pin or needle and press into that dot you will hear it tick back into place. you have reset the switch now. You will probably need to clean the inside of the heater element unit to get rid of the fluff particles or it will keep switching off. To take this apart you will need a set of Star screwdrivers. Its a bit tricky but you will be able to undo the star screws and take them all out. I will add some photos to show you the unit apart. You can see the build up of fluff on the photos i have added from my hotpoint WD860 heater unit. This is a tricky job and takes about an hour due to the screw being awkward to take off and put on again but mine hasnt faulted for 2 years since sorting it out. You can buy a new Thermostat switch which is about 10 pounds sterling from Hotpoint or other spares stores.
