Electric pressure washers are designed to be relatively inexpensive, and one way they achieve this goal is by constructing many of its components out of thin plastic. However, when subjected to high temperatures, plastic that is of a thinner gauge is more likely to melt.

Components that have melted offer a significant threat because they may expose the electrical components to water. This might cause severe damage to the pressure washer, rendering it unsalvageable.
