CLEAN FRESH WATER IS IMPORTANT FOR THESE PUMPS, I ALWAYS USE A HIT OF ARMOR ALL IN THE PUMP AFTER USE . YOU MIGHT SEE IF IT'S GETTING POWER TO THE MOTOR MIGHT HAVE A BAD GFIC ? PLUG IT IN PICK UP THE UNIT AND TRY DROPPING IT FROM A FOOT OFF THE GROUND, THIS JAR MIGHT SHOCK IT BACK TO LIFE ?. Jay the pool pump whisperer FLORIDA 32750

If you can hear the vac squeaking as you run across the window, you've just not applied enough liquid. Just go over the window again with the spray bottle and microfibre cloth and then vacuum the liquid away.

This happened to my FC5 too. I found that the detergent outlet within the suction head was clogged up. This is the receptacle for the brass nozzle you can see when detaching the suction head (by pressing the grey button and gently pulling on the yellow "cover" at the top of the cleaning head - Figures 16.1 and 16.2 in the manual). To check it is indeed clogged, put a few drops of water in it - they won't drain out. To purge it I used the jet from a handheld steam cleaner, and I also used the steam jet to clean the suction slots. Be very careful not to scald yourself, wear gloves, and when cleaning just pulse the jet so as not to risk damaging the plastic parts.

The best thing is to get a complete pair of quick couplers. One male one female and replace the ones you currently have. Stick the male on the washer the female on the hose and as they are the same should be able to hold under the pressure of water.
