Gas water heater to open the hot water valve does not start is how is it? Wash basin with hot water can start, shower and kitchen do not start what is the reason?
Shower and kitchen water flow caused by small, appropriate adjustment of water heater water sensor switch position, the need for professional staff to do.
There are two possibilities: one is the shower damage, the other can be connected with the shower valve is broken. You can remove the shower head, if the hot water that is the shower damage, if not hot water that must be a bad valve. hope this helps!
Insufficient water pressure.
Gas water heaters are anti-dry protection, no ignition when the fire. Only when the water pressure to meet the requirements, to have cold water into the gas water heater before the ignition work, and hot water outflow.
The height of the washbasin is generally below the height of the shower and the kitchen waterway when the family waterway is installed. The higher the outlet, the higher the required water pressure. When the washbasin out of the water outlet when the water supply to the water heater to detect the pressure just to meet the working water pressure of water heaters, water heaters will work. And the shower and the kitchen due to the reasons for the high outlet to the water heater to detect the pressure can not reach the water heater working water pressure, the water heater can not start work.
