    Could be a faulty main circulation pump capacitor, more likely to be a siezed circulation pump motor though. 😥

    Is this easy to replace / check for bits stuck in it, if so is there any info on where and how to do this.

    In a word no.

    Circulation pump blockages are not very common.

    Access is very difficult, its in the base, front left. You can see it from the front if you remove the door panel and the large lower plinth at the front.

    Might just be possible to see if it is siezed and also check the capacitor.

    Be sure to remove the mains plug before you open it up.

    Mine is most likely seized too.

    I tried your instructions and removed the lower plinth (easy when the decorative part (wooden piece) of the door is off or when the dishwasher is on its side).

    The only pump accessible from the front is the one draining the water away. That moved freely as I could turn the thing that looks like a fan.

    I could not see much else but the salt reservoir so I put the dishwasher on its side and removed the bottom plate (4 screws; easy). Then I saw the big motor at the back of the dishwasher (part 4998101 nbr 992526 F, type 31-62/2 -02-) but had no clue on how I could turn it to remove the seizure. All the moveable parts were shielded.

    That is when I gave up as the next step seems to be loosening the wire that holds the plastic basin (visible from inside the washer) against the metal, by going all around the circumference of that plastic. It seems that then I can remove the 3 hoses that
    are attached to that motor and get access. This is not trivial as I was not sure I can put it all back together.

    How can I free that seized pump/motor?

    Have you tried turning the rotor to see if it is in fact seized? Access to the motor only after removing the right hand side panel by the way.
