I have the same machine.
It made a noise similar to boiling a kettle before giving up.. then the "fast wash" LED would blink.
A bit of fiddling shows that the output pump is faulty... seizes up every now and again, as this is a portable unit flushing water backwards through the waste pipe gets it going again, but the pump will need replacement.
if your going to replace it, remember to pull the plug out (not just switch off) all the Neutral wires are bare in the dishwasher and could trip your saftey switch.
Just pulled mine out to look on ebay numbers written on the pump are
