Wireless Control Module TroubleshootingUpdated 10 days ago
The RED FAULT light means there is likely a short in the cable feeding to the module. Please check all your connections, especially for proper grounding.
The BLUE fault light means there is “over amperage”, but how this over amperage is caused can be for various reasons.
Please measure voltage at the outlet where the unit is being installed to ensure there is no voltage drop in the lines. If using an extension cable, please ensure you are using a cable of sufficient gauge, and less than the max recommended length.
All electric pressure washers observe an amperage spike when they are switched on. Please back off the unloader valve by turning the knob counter- clockwise before switching on the pressure washer, and then gradually turn the knob clockwise to build pressure. Failure to do so could trip the circuit breaker. It would also reduce motor life considerably.
If the breaker trips before the unloader valve knob reaches the maximum limit, please stop turning the knob. Turn the unloader knob counter- clockwise a little and mark that spot as the max operating condition.
To rule out issues with the module, please plug the motor directly to the power source instead of the wireless module, and see if the machine works okay like that without tripping the breaker. If it works fine, then there is an issue with the module itself.
If the module is fine, then first look for a clog somewhere in the system. Please visually check the gun, hose, and unloader valve. You may have to take the unloader off the pump to visually inspect it. If the issue is an internal component of the unloader, you will not see anything.
Please plug the motor back into the module.
- Run the machine without a nozzle at the tip of the gun. If it works fine, then the nozzle is clogged.
- If it still goes into fault, run it without the gun.
- If it still goes into fault, run it without the hose.
- If it still goes into fault, run it without the unloader.
At each of the above stages, please make sure you are feeding water into the pump.
- If it still goes into fault, then please take the pump off the motor and run it. If the motor spins freely, and the module does not go into fault, please turn the pump shaft manually to see if there is any interference.
What we are trying to figure out here is what component is causing the motor to work extra hard.
Please reach out to us [email protected] after this troubleshoot with your order number and findings. A short video of the system would be very helpful.
