Numatic Answered Questions & Fixed Issues

There are a few potential causes for why your Numatic George wet/dry vacuum is not spraying and only producing a faint buzzing sound. Here are some troubleshooting steps you can try:

1. Check the water level: Make sure that the water level in the tank is sufficient and not too low. If the water level is too low, it can cause the spray function to malfunction.
2. Check the water supply hose: Make sure that the water supply hose is properly connected and not kinked or damaged.
3. Check the spray nozzle: Make sure that the spray nozzle is not clogged and is able to rotate freely. If the nozzle is clogged, it can prevent the spray function from working properly.
4. Check the motor: If the motor is not functioning properly, it can cause the spray function to malfunction. To check the motor, you can try running the vacuum without the hose or attachments to see if it is functioning properly. If the motor is not functioning properly, it may need to be repaired or replaced.

If these troubleshooting steps do not resolve the issue, it may be necessary to take the vacuum to a professional for repair.

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 www.a1cleaningsupplies.co.uk they can post a replacement. Otherwise outside or even within the UK you can contact the manufacturers technical people. Website is www.numatic.com

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.

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.

When you say it wont work, what do you mean?

replace the unit

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.

You say that you have checked the belt, so I assume that you ensured that the belt is engaged properly and is not slipping. When you press the switch on and then off, do you hear the belt drive motor turning? If not, then you either have a defective drive motor or a defective switch. Testing the switch will give you the answer. To do that, first unplug the vacuum from the wall outlet and then gain access to the switch connections be removing any parts that prevent such access. Using an inexpensive digital multimeter set to read ohms, touch the two probes together and you will see the meter reads 000.0 and that is the same thing you should see if touching the probes to the switch connections with the switch in the "ON" position. In the "OFF" position, the meter should show something other than zeros, or show no reading at all. If your readings are as they should be, the switch is good and you then need to ensure that the wires connected between the switch and the belt drive motor are in fact connected securely and are not loose. If the connections are good then next you need to determine if you are actually getting power to the switch, and if you are then the belt drive motor is the suspect. If you don't know how to test for power at the switch using the meter or a test light then you should ask someone to assist you who does have that knowledge in order to avoid the possibility of electrical shock. If there is no power to the switch, there is obviously a bad connection between the switch and the power cord which feeds it, so you would need to trace those connections and determine the cause.

wtf you dont the wires are hard wired to the motor

pump f%^$£d

thermal switch

at the bottom

replace it

because its f^%$£d
