Dishwasher Bosch Series 6 - not working (Bolton CA16)

Our dishwasher has ceased to function. Being old and decrepit (me, not the machine) and having no desire to learn about the inner workings of dishwashers, we are replacing it. Which is to say, if anyone would like a dishwasher in need of fixing, you are welcome to come and collect it (asap). It is a Bosch Series 6 freestanding machine and is showing error code E-15. Bosch say there is no DIY fix; YouTube offers several dozen enthusiastic (and several rather bored) chaps giving advice on DIY fixes. Alternatively, if anyone wants to take it and harvest its internal organs for transplant or experimentation, you would be welcome! Needs to be gone by 6th Jan to make way for new machine
