Step 1: First cut off the power supply to ensure safe operation. The wiring mode of the steam generator heating tube can be taken with the mobile phone in advance for reference for rewiring after replacement, and then loosen the heating tube connection line.
Step 2: Drain the sewage from the generator before officially replacing the damaged heating tube.
Step 3: After the sewage is exhausted, use a wrench to unscrew the heating pipe and remove the damaged heating pipe. Then clean up the residue inside the generator. After the residue in the boiler is treated, smooth the surface of the connecting port with coarse sandpaper to ensure that the connection is tight and watertight.
Step 4: Smooth the surface of the connection with coarse sandpaper to ensure tight connection without water leakage.
Step 5: Tighten the screws, connect the wires in the correct way before, and check and reinforce the screws at the connection frequently.
Step 6: After the connection is completed, check the voltage at the steam generator switch with the multimeter to ensure that the input voltage is correct, check and strengthen each connection.
