Troubleshooting
Fault
Failure Cause
Solution
Water Not Heating No plugged or hydraulic pressure too low Check the power supply circuit wire is connected
and the minimum use water pressure not less than
0.04MPa
Low Water / High
Temperature
Too much water or the voltage is to low Decrease water pressure, check the power supply
and use of voltage
Water Outlet Low Water inlet blocked or hydraulic pressure
too low
Check inlet filter for dirt and remove it and then
increase water inlet flow and pressure to low.
No Indicator Light Hydraulic pressure is too low, can’t open
power supply or circuit fault
Use the water heater when the hydraulic pressure
is normal level.
