HOW DOES ONE CONNECT A BISSELL **7901 SERIES**PROHEAT AUTO MIX PISTON TO A BISSELL AUTO MIX KNOB???
Take of the housing ,turn it over and you will see the under side of the auto mix dial , Then turn the auto mix dial to rinse only;
On the top of the piston you will see a small slot , this fits into
the out side spiral on the auto mix knob with the dial set to rinse only the top part of the spiail sould point to the courner
Tilt the piston slightly,then hook it on the point of the auto mix knob , when you turn the auto mix dial to heavy traffic the piston should slide down the outer spiral of the auto mix-dial ,
Put the housing back on with the auto mix dial set to heavy traffic, but make sure no tubes are trapped or this will stop the flow of water,
i hope you can under stand what i have wrote ,Goodluck
Thank you for this posting, without it I would have not gotten the cleaner back together. At least not without breaking pieces. Greatly appreciated
