What to do if the red LED for water flow lights up and the JOSAM JH1500 Electric Heater switches off?
If the red LED for water flow lights up and the JOSAM Electric Heater switches off, it indicates a fault with the cooling water flow. This can be due to several reasons: the water level being too low (in which case, top up with fluid), a blocked pump filter (clean the filter), or a blocked water hose (try cleaning it with compressed air).
Why does the handle get hot during heating with the JOSAM JH1500 Electric Heater?
If the JOSAM Electric Heater handle gets hot during heating, it's likely due to a bad connection between the heating tip and the handle. To resolve this, follow the instructions on how to clean the surface between the heating tip and handle.
What to do if the red LED for overheating lights up and the JOSAM JH1500 Electric Heater switches off?
If the JOSAM Electric Heater's red LED for overheating lights up and the heater switches off, it means the temperature in the electronics or the cooling water is too high. Allow the heater to cool down completely. Once cooled and the LED is no longer lit, you can use the heater again.
Why does the RCB trip when turning the JOSAM Electric Heater on?
If the RCB trips when turning on the JOSAM Electric Heater, it indicates a ground fault has occurred. Inspect the hose kit for any damage, and if necessary, change the hose kit.
Why is the operation LED blinking fast at start-up on my JOSAM Electric Heater?
If the JOSAM Electric Heater's operation LED is blinking fast at start-up, it means the heating button is being pressed while starting the machine. Release the button. If the issue persists, the heating button may be faulty, and you should replace it before restarting the machine.
Why is the LED for overheating blinking at start-up on my JOSAM JH1500?
If the JOSAM Electric Heater's LED for overheating is blinking at start-up, it means the electrical section is overheated, or the temperature sensor is providing an incorrect value. Allow the electrical section to cool down until the LED is no longer lit. Check for loose connectors, and if necessary, replace the temperature sensor.
Why is the LED for water flow blinking at start-up on my JOSAM JH1500 Electric Heater?
If the JOSAM Electric Heater's LED for water flow is blinking at start-up, the water flow sensor is likely giving an incorrect value. Check for a stuck paddle in the water flow sensor, and if necessary, replace the water flow sensor.
What to do if the JOSAM Electric Heater doesn't work, but the mains current is sufficient?
If the JOSAM Electric Heater doesn't work despite sufficient mains current, the residual current breaker may have triggered. Identify the cause of the error and take appropriate action, then reset the residual current breaker.
How to troubleshoot no current to the JOSAM JH1500?
If there is no current to the JOSAM Electric Heater, first ensure the heater's plug is properly inserted into the wall socket and that the wall socket has power. Check the main fuse or residual current breaker. Also, check for any loose connections in the plug or wall socket.
What does it mean when the 2 red LEDs (water flow and overheating) blink simultaneously on the JOSAM Electric Heater?
If the 2 red LEDs (water flow and overheating) blink simultaneously on the JOSAM Electric Heater, it indicates a phase fault or a current sensor fault. Ensure all phases are available in the socket, no fuse has been triggered, and the cable is undamaged. Also, check that the current sensors are undamaged and properly connected.
