I had the same problem with the bosch wft2800 washer dryer recently.its about 8 years old
freezing on the programme cycles.
clicking noises in the background .
i found the fault was on the power module board located next to the motor .
after removing the board carefully.i inspected the board and found one of the soldered relay legs was dry jointed .i then cleaned the connection and resoldered the relay .also futher inspection of the board revealed more bad solder dry joints forming on all the other relays.i resoldered these as well.the last thing you want is stripping the w/machine again for the same fault a few months later!!
(shrack relay 10amp 12v-240v)
once put back together it worked perfectly.
to buy a new power module cost is £240++(worth the stripdown for a diy repair)
another fault i had after 3 years of ownership of the washer.
blowing mains fuses/tripping rcd circuit.washer dead.
cause was the interference suppressor .there are two,the bigger one was faulty.
bosch part number, 09 4567
i hope the above info helps anybody with same problems i had .
as with any electrical items before opening the machine.MAINS POWER OFF !!. ELECTRICITY KILLS !!!
if you do not have the repair ability.get a QUALIFIED ENGINEER to do the job.
