Bissell Big Green leaking clean water
I've had the Big Green for a few years, and now it as soon as I turn it on, water from the clean tank pours out from the bottom and the flow indicator spins like crazy until the water runs out. The last time I used it a couple of weeks ago, it was fine.
I've tried pressing and releasing the trigger many times to ensure it's not stuck. But no difference. It could be the solution valve at the bottom or the solenoid valve. How do I figure out which of them it is before I try to replace it?
