Hi i have a fault saying f13 what is this

Hi
f-13 is heating element or thermostat
Replacing thermostats will solve your problem..
1. You’ll need to use a combination of finesse and brut force to get the lid off of the machine. It is secured by two screws at the rear but has troublesome plastic hooks inside, half way down either side, that stop the lid from riding up at the front. The process is to remove the screws and then pull back and up to ‘unhook’ the internal brittle plastic hooks. I found this scary and difficult, cracking sounds were off putting and I did break to tips of the plastic hooks a little but they still seem to work ok. Be careful and wiggle it gently from side to side is the only advice I can offer.
2. Once inside it gets a bit easier. You should be able to see a metal snail-shaped object bolted to the top of the drum with various electrical connections – this is the dryer and within it are the two thermostats. What you’ve got to do is remove/unplug all the electrical connections from the top dryer, of course, make a diagram first as you’ll need to put them all back after. You then need to unbolt/unscrew the top half of the dryer and remove this from the machine – this is another fiddley bit and you have to have a very small ratchet socket set which will make the hard to get to bolts/screws accessible.
Note: some of the screws are the Torx type (imagine a more complex Phillips’s type screw). You’ll need to have a Torx type screw driver head that’ll fit the small socket tool to undo these.
3. Once the top of the dryer unit is off, you just need to remove the thermostats – one is fixed in by screws on the outside of the dryer top and the other is fixed in by screws on the inside. Screw in the replacement thermostats, then clean off the fluff and burnt fluff from both halves of the dryer and you’re there – put the machine back together.
