Can I use hot water with Karcher pressure washers?

No, Karcher pressure washers are specifically designed to operate with cold water only. Using hot water with Karcher pressure washers can damage the pump and other components, leading to potential malfunction and costly repairs. The internal mechanisms of these pressure washers are not designed to handle the high temperatures of hot water, which can cause seals and O-rings to deteriorate and fail. Additionally, using hot water with Karcher pressure washers may pose a safety risk, as the machine's spray gun and hose are not designed to withstand extreme heat. It is important to always follow the manufacturer's instructions and guidelines to ensure optimal performance and longevity of the pressure washer.
