I can't seem to remember all the parts in that particular accelerator but many models have porous metal filters. Once these are wet they need to be thoroughly dried or even minor changes of air pressure can cause them to operate. This may take several days so it's best to have a replacement or spare. And once again I don't recall if these are in a Central A accelerator.
