Notice Regarding Inspection and Repairof Built-In Dishwashers
Rinnai Corporation has decided to provide free-of-charge inspections and repairs ofcertain models among its built-in dishwashers produced between December 2004 andOctober 2007. Potential internal water leakage in the models in question could reachelectrical substrates and/or internal wiring. In extremely rare cases, it has been
determined that the so-called tracking* phenomenon in the electrical substrates orconnectors could give rise to odors or smoke, which could potentially result in the firedamage to the product.
* Tracking: Phenomenon in which dew condensation and other water particles combine withaccumulated dust, leading to electricity flows that result in heat generation and fire.

To date, the aforementioned issue has caused fire damage to the product andperipheral areas on two occasions (December 2011 in Hokkaido and February 2012 inIbaraki Prefecture). Rinnai takes these incidents very seriously and sincerely
apologizes for anxiety caused to customers. We will work hard to ensure to prevent arecurrence in the future.
