Drainage from temperature/pressure safety valve |
It is normal that less amount of steam is exhausted every heating |
Normal |
If there is continuous drip ,safety valve may be blocked by foreign matters |
Raise the handle and drain the water for several seconds .Return the handle mildly. Repeat the mentioned actions several times |

Normal |
Vibration of water pipe produces the sound due to fluctuation of water pressure. |
It is normal and close the cold-water isolation valve temporarilly |
|
If there is noise during the heating, sediment may exist at the bottom of cylinder. |
