You have a problem with the electrical switches. If you are comfortable with this, take apart and double check internal wiring to make sure nothing was frayed, or disconnected. Make sure it is unplugged. If you know how to operate a multimeter, you can use it to check continuity in each switch.

You will need to replace the hose, which has the on off switch built into it, and this will solve your problem
