Water filling valve
No Symptoms and Causes

cannot stop water and heating water.
2 Water overflows due to an internal sinking
of the hot water heat exchanger.
Others Failure
Internal Check splitter valve's material
diaphragm
Check hating pipeline condition
<Fig. 1>
- There are many impurities in the heating water
of the heating pipeline and in the water pipeline
that are stuck on the water filling valve solenoid
diaphragm and water slowly flows
and clean the solenoid.
- Especially, in case the splitter material is
aluminum, corrosion is fast and there is
formation of much impurities. Replace with a
splitter in copper or stainless steel.
- If water still overflows after the checking above,
it is an internal sinking of the hot water heat
exchanger and the hot water heat exchanger
has to be replaced.
