Troubleshooting and error codes
| Problem | Possible Cause | Solution |
|---|---|---|
| 1. The machine will not run. | Ensure power connected to machine is on. If machine still will not run, remove cover from control box and test for presence of power supply at top of left side contactor. If no power at contactors, test power supply at power source. If power supply is ok at source but there is no supply at contactors in control box, check connections inside accessory power point. These checks should only be performed by a licensed electrician) | Ensure power is connected and ON. If still not running, consult a licensed electrician for diagnosis. |
| 2. The machine makes a low humming sound when switched to ON. | This indicates there are only two-phases of power supply at the motor. | Switch off machine immediately to avoid motor burn-out. Have an electrician check the machine for the missing phase. If all three-phases are ok at motor, the motor may be faulty. |
| 3. The machine will only run in one direction. | This indicates a problem with either the FWD/REV switch mechanism or one of the contactors. | Have an electrician test the machine. |
| 4. The machine will run but there is not power at the accessory power point. | Check connections inside accessory power point. | Inspect and correct connections. |
| 5. The machine does not have much suction. | (A) Inspect inside secondary filter housing and make sure secondary filters are not blocked with dust. | If blocked up with dust, remove and clean filters by either tapping out or using compressed air. |
| If large amounts of dust present in secondary filter housing, this indicates a problem with the primary filters (hole or came loose). | Check primary filters for small holes or perforations. Small holes can be repaired/patched using silicone sealant. | |
| (B) Make sure flap in bottom of collection cone is closing properly and creating a seal. | If this flap is not functioning properly, machine will tend to suck up dust bag when switched on. Ensure proper closure. | |
| 6. The machine is blowing dust out the exhaust. | (A) Secondary filters are not installed properly and dust is bypassing them. Ensure seals on the ends of the secondary filters are creating a proper seal. | Check installation and seals of secondary filters. |
| (B) Secondary filters may need replacing. | Replace secondary filters if necessary. |
