You will need to remove all the wires off it and off the hi/lo rocker switch. Then disconnect to two wires on the opposite side of the on/off to the power in side. The two white motor wires then get connected to this switch. The machine will now run on high speed only when turned on.

Chris, I hate to be the bearer of bad news, but you've already guessed it. You need a new machine. Personally, if I were you, I'd check into the small shop vac's, type of vacuum. Craftsman has a good one that I've been using for, wow, more years than I can remember now. I had it a long time I know that. I actually picked up a spare one at a garage sale last summer and put it up on a shelf for one my old one finally bites the bullet, but so far, it's still going strong. The wet/dry vac's have a float system in them that actually plug the bottom of the air chamber where the vac draws it's air from, when the water gets too high in the tank. The motor starts to race faster than normal and that's the tipoff that it's full. Dump out the tank and go at it again. Better luck this time.

Sounds more likely to be the switch than the motor, especially if it is the model with the top switch rather than the side "rocker" switch. If you are in the UK, speak to the technical people at they can post a replacement. Otherwise outside or even within the UK you can contact the manufacturers technical people. Website is

They suggest to store the unit at room temperature (68 F). The lowest in theory is above 32 degrees F. Anything below that will freeze and cause damage.

The rule of thumb is that if you can put your hand in it, then it is okay for the machine. If it is too hot then you will distort the container. Once distorted it can't be fixed, and will need replacing. As for cleaning liquid, this goes in what is called the solution container, and once again, any liquid/chemical needs to be of a strength that you can safely put your hand in.

What is wrong with the yellow flashing light? This is a bag full / low air flow indicator. If your bag is not full then you most likely have a blockage in the hose, wand or tool.

If any moisture has entered the vacuum at any time then this will cause a musty smell. Does the primary filter have discoloration or a yellowy stain on it? this usually indicates moisture has been present at some stage. Replacing the filter may help or you can place a small sachet of air freshener beads (glade) in the bottom of the canister under the bag. This will give a pleasant smell whether vacuuming or blowing.

It can be disabled to stay in high mode, but you need to know what you are doing. It basically involves removing the small PCB and connecting the motor wires directly to the on/off switch. The hi/lo switch can be left in place (although not connected) or removed and a blanking plate put in it's place. You can leave a hole as this is a potential hazard and against government regulations.

If the machine is vibrating while on, then this would suggest that something has caused the motor to become out of balance. This could have been cause by some foreign object being allowed to go through the motor, dampness/moisture through the motor causing the bearing to collapse. Either way the motor will need to be replaced.

If it is a recent model 2007 onwards, it may not be too successful, but you could try if absolutely necessary. Although not normally required, earlier filters can be gently washed by hand in a soapy solution, thoroughly rinsed and left to dry naturally.
