lamp
1) Make sure power supplier is available, by checking house
power supply voltage;
OFF
2) Make sure the "test" button is not mistakenly pressed, by
pressing the "reset" button. -only for m odels with ELCB.
1) Make sure the water heater is turned ON, by pressing
ON/OFF knob;
OFF
2) Make sure water pipe connection is right (inlet on right, outlet
on left).
1) Make sure the wate flow rate is not too big (over 6L/min), by
ON
reducing the flow rate through water valve regulation;
1) stop to use water heater, call service technician.
lamps
1) Make sure temperature/power setting is not too small, by
choosing higher temperature/power setting.
2) Make sure the wate flow rate is not too big (over 6L/min), by
reducing the flow rate through water valve regulation;
3) Measuring the actual voltage WHEN heating to make sure
ON
voltage drop not too big.
By increasing sectional area of, or reducing length of the power
supply cable could improve the problem.
4) Make sure power supplier voltage not too small, by checking
house power supply WITHOUT heating.
1) Make sure the water pressure is big enough to provide you
confortable water flow rate. (for water heater without pump, water
tank should be at least 3 meters higher than water heater)
2) Make sure there are no dirty blocks the water flow, by cleaning
/
the filter, which is built in the water valve.
3) Make sure there are no dirty blocks the nozzles of shower
head.
4) Make sure there are no bottle neck Between the water inlet
pipe and the main water supplier point;
/
1) Check if inlet temp higher than setting temp.
1) Measuring the actual voltage WHEN heating to make sure
voltage drop not too big. (voltage drop should be less than 10%).
ON
By increasing sectional area of, or reducing length of the power
supply cable could solve the flickering problem.
