A:Answer A few quick solutions, check to see that the float in the Dirty Water Tank is not locked. It should float freely and when it doesn't the machine thinks the tank is full. Next, it sounds simple but this can happen if there is too much water in the Dirty Water Tank. Just empty it and try again. Last, ever though you've only used it a couple times, the suction is strong and can pull a lot of debris out of the carpet, it sounds like there could be a clog in the nozzle or filter. Check in the nozzle for clogs and the nozzle inlet for tangled hair. If non of these quick solution work, please contact us at 1.800.944.9200 so we can better help solve with problem with you.
