A repair along the way…

This post is by way of a small diversion.

We have a Vax upright vacuum cleaner that has done sterling duty for a while until recently when it developed an intermittent fault, it would stop and then start again, clearly a broken contact or wire.

Having looked at the makers information and generally on the internet there was no repair details available. Not willing to pay the cost of a new vacuum for somebody to look at it I decided to open it up and see whatI could do.

Having no information at all meant that I had to take small steps and remove screws and other fixings to see how it was held together. I had previous experience of repairing Dyson vacuums so knew that unorthodox “shortcut/cheap” methods of holding bits in place would be used.

The Stripdown:

Remove the long flexible hose (squeeze the tabs on the fixed end), the dirt tank/ filter assembly and the felt filter underneath.

With the vacuum face down remove the lower curved hose support for the long flexible hose – one short screw and two long ones.

  

Remove the short flexible hose support – one short screw.

Pull the handle assembly clear of the base part and remove.

Remove the  upper part of the base assembly, turn the base upside down and remove two short screws, one at each front corner near the brush ends. Remove one short screw near one of the rear wheels. The upper part can now be gently prised clear of the base unit.

   

Remove the red rubber front bumper, this just pushes into place on the cover.

Remove the brush roller by gently prising the roller upwards and forwards on the belt side. The roller is held in a short diagonal slot here. Remove the belt from the roller and motor shaft.

Turn the base unit the right way up and remove two short screws from metal clips at each side of the motor. One of the clips can be removed, the other clip by the red handle retaining “button” can be moved sideways enough to remove the motor assembly.

On the top of the motor assembly is a rubber sealing ring, remove this.

The motor covers are held together by six short screws. One of these is a T20 Torx screw and one is hidden under the red stop/ start switch actuator 

To remove the switch actuator prise gently at the side of the uppermost part of the switch actuator, this pivots at the top end. Remove the actuator and spring underneath.

Remove the six screws holding the two motor halves together and pull one half away from the other. The motor can now be lifted clear of both cover halves if required.

The motor position should be noted before removal. There is a mesh filter and sponge protecting strip with the motor assembly. Note the positions of these before removal.

The mains cable is held in one half by a short screw and plastic retainer.

The motor is connected to the mains cable by crimped connectors and also small spade connectors to the switch. There is a capacitor across the wires.

The switch is held in place by a short screw.

My problem was an intermittent connection I replaced the mains cable. This involved removing a crimped connector and pulling off a spade connector from the switch. The new cable was connected using a new crimped connector and spade connector.

I wired up the motor and then tested it befor Reassembly.

The Reassembly:

Reassembly is essentially the reversal of the above procedure. The switch actuator is placed in position along with it’s spring and the pivot end sharply (not heavily) tapped into position, I used my screwdriver handle.

Remember to replace the short screw under the switch actuator before replacing the actuator.

Align the motor before replacing the clips and securing.
