This topic has been raised before, but I was advised by Mumsnet to start a fresh thread. My Vax Powermax has not been sucking up the dirty water. I looked up the Vax troubleshooter. Its most useful advice is to take off the dirty water tank, turn on the motor and check the hole by the motor to see if it is sucking. It was blowing rather than sucking. Getting competent advice from the Vax Chat on troubleshooter, was a waste of time. The staff could not offer an explanation of the fault or how it could be rectified, except to buy another machine. The model does not have any hand attachments nor a switch to reverse the motor direction. Can anyone help?
