I have just repaired a Proheat 1698 for a friend. In doing so I read all the reviews particularly noting that there were so many with no water flow to the sprays. This was the case with this machine. The problem was caused by scale from the heater blocking the outlet from the heater to the sprays. To cure this the tool holder needs to be removed (2 bolts and 2 screws), then lift the handle away. Remove 2 screws lower down on the body and push the clip at the top in the recess where the trigger operates a valve plunger. This then gives access to the pipes and heater that can easily be removed and cleaned. I am surprised that Bissel do not recommend using soft water in this machine as the hose ports are small and easily blocked. Without this problem I am sure that the machine would have a much better rating!
