2. Contact authorized 

service personnel for 

repair.

1. Rotate “TEMP” knob

2. Repair or replacement 

    the PCB

1. Press the reset handle 

    of the thermal cut out  

    after checking and 

    troubleshooting
2. Change the heating 

    elements

3. Adjustable water flow 
4. Change the flow sensor  
5. Open the flow sensor 

    and clean the rotor 

1. Wait for restoration of 

running water supply;

2. Open the inlet valve of 

running water.

Adjust the heating power 

lower, make the water 

bigger.

Contact authorized service 

personnel for repair.

REASONS

1. Power supply error;

2. PCB error;

 

 

1. The “TEMP” knob is off;

2. 

3. The water flow 

insufficient 1.2L/min;

PCB error;

4. Impurities clogging the 

flow sensor of the rotor 

1. The running water 

supply is cut off;

2. The inlet valve of running 

water is not open.

1. Water pressure is not 

stable.

2. Outlet water temperature 

is too high, overheating 

protection again and 

again.

 

 

 

Electricity leaks.

Temperture sensor 

is broken

Change the temperture 

sensor 

SYMPTOMS

The heating indicator light
