- Dryer not on
- Dryer smoking
Step 1: Identify the problem | Step 2: Heater errors | Step 3: Fuse | Step 4: Next steps |
---|
Step 1: Identify the problem
- Is the dryer on? If not;
- Is the Vehicle system on? (If not, refer to Vehicle System Troubleshooting)
If the screen on one dryer is not illuminated, the issue cannot be fixed on shift; proceed to step 4.
- Is the Vehicle system on? (If not, refer to Vehicle System Troubleshooting)
- Is the drum spinning after pressing START? (If not, this is likely a failed blower fan and cannot be fixed on shift; proceed to step 4)
- Is the red LED light next to the start button on and solid?
- LED light is flashing (proceed to step 2)
- LED light is off (proceed to step 3)
- Is the dryer smoking?
- Has there been recent rain or is the air temperature cold? (If yes, this is normal dryer function; continue to monitor)
- Is the smoke white or light grey, and dissipates after approx. 10mins (If yes, this is normal dryer function; continue to monitor)
- Check the LED light again, is it flashing? (If yes,proceed to step 2)
- Is the dryer drying clothes sufficiently after 30 minutes - 1 hour?
- Check the LED light again, is it flashing? (If yes,proceed to step 2)
- Refer to the Waru Dryer Resource Hub
Step 2: Heater Error Codes
Error codes
- Identify how many times the LED light is flashing (with a 4 second gaps between sets). Count the flashes with the volunteer.
- Refer to the table below to identify the heater fault
Error codes (1-4, 10, 11)
- Can likely be resolved on shift
- Will not require an incident report
Flashes | Fault | Description | Next Steps |
---|---|---|---|
1 | Fuel | Insufficient fuel - the dryer is not receiving sufficient fuel which may be due to insufficient fuel, a false fuel gage, or a fault in the line. |
|
2 | Fuel/pump | Insufficient fuel/fuel pump fault |
|
3 | Electrical | Low voltage cut-off - the dryer is not receiving enough power which could be because of a low battery, poor connection or an electrical fault. |
|
4 | Overheating | Ambient temperature too high |
|
5 | Overheat protection | Overheat protection switch has been activated by the dryer |
|
10 | Overheating/Other | Issue unknown - the dryer is cold. |
|
12 | Control | Control switch failure |
|
Error codes (5-9, 11, 13)
- Likely cannot be resolved on shift
- Try vehicle system powering on and off; and proceed to step 4.
Flashes | Fault | Description | Next Steps |
---|---|---|---|
6 | Control | Replace controller | No on shift fix |
7 | Electrical | Check fuel pump lead connection | No on shift fix |
8 | Fan | Faulty or damaged heater fan | No on shift fix |
9 | Glow plug | Faulty glow plug | No on shift fix |
11 | Sensor | Replace overheating sensor | No on shift fix |
13 | Combustion | Maintenance required | No on shift fix |
Step 3: Fuse Reset
- Remove the cover from the fuse box (this can be a clear plastic cover, a rubber cover or you may need to turn a dial to open).
- Locate the fuse you need to reset, the fuse will labelled according to the appliance.
- Pull out the fuse; you may need to wiggle the fuse with your forefinger and thumb up and down (DO NOT WIGGLE FUSES LEFT TO RIGHT), if plastic tweezers are available you may use them.
- Re-insert the fuse.
- Replace the cover to protect all the fuses.
Step 4: Communicate the next steps with the volunteer
Diagnostic complete, the issue cannot be resolved on shift. You will need to either
- Run the shift with reduced capacity
- Have a conversation only shift
- Pack up and go home
Clearly communicate the options to the volunteer as per the Decision Guide and ensure an incident report has been submitted in order to alert individuals according to the escalation process.
Requirements for an incident report:
- What was the first indication of an issue?
- What steps were followed on Service Support?
- What was the shift outcome?
