Why is it beeping and stuck on the wool cycle

I suggest you check the fuse on electronic module which is located to the right side of the drum. Getting to it no easy task as you must remove the rear panel and top cover and jam an object thick enough for your arm to passbetween the drums and the machine body. Please ensure you earth yourself before touching this pcb as the static in your body may blow the intergrated circuits and eproms.
I hope this solves your problem.

Hi from retired Englishman in SW France,
(no promises but try this!)
I would gently suggest as a first step that you clean the drain motor/pump lint tray/filter. So many 'faults' are caused by blocked filters and many machines will not even go to rinse or spin or release the door lock if there is any water still left inside.
Here are my complete and generic guidance notes for checking both the drain motor filter and the drain motor ;-0)
If you are unsure where the filter is, it is often behind the front lower (kick) panel (or in some machines at the rear in an awkward position!). These panels are either held on by (plasic) screws or will just pull off. Most filters are held in by a round cover/knob. Sometimes the filter will not come out with the cover and you will have to persuade it to come out to play.

REMOVE POWER AND ENSURE YOU HAVE A WATER RECEPTACLE/RAGS TO SOAK UP THE WATER WHICH IS BOUND TO POUR OUT (alternatively use a wet vac as sensibly suggested by VinnyB1234!)
It's surprising what people have found in theirs! It is always worthwhile checking it on a regular basis.
Now- whilst the filter is removed it is normally possible to see the drain motor and ensure it is not jammed by a foreign object such as a needle or a toothpick. It should be able to be turned by hand/finger- the power IS OFF!
At this point it is also possible to test if the motor works. No clothes or water in the machine, select a spin cycle and put the power back on. You should be able to see the motor turning at some point, possibly straight away. Using something suitable like a glove see if it is easy to briefly slow the motor down. If it is easy then the motor is malfunctioning.

If this has assisted you please consider a 4 thumbs up for the rating.
Thanks and good luck!

Clean your machine by using a cotton wash at 85'C without anything in it, and with no detergent.
Also, empty the coin-trap at the bottom left (front of the machine).
Also, remove the detergent drawer, clean by hand. While the drawer is out clean the dispenser area with mildew cleaner.
You can also try using Sodium Metabisulphite (see a homebrew shop). Avoid using bleach as it damages the stainless steel.
In between washes you can leave the inner door slightly ajar to allow it to dry out between washes.
