What it does:

The pressure switch senses water pressure in the system and closes the electrical circuit to the burner when sufficient pressure is present. If water flow stops or pressure falls below the operating threshold, the switch opens the circuit, shutting the burner off to help protect the heating coil from overheating.

Why it matters:

A faulty pressure switch can cause:

• Burner won't ignite

• Burner remains on when it shouldn't

• Intermittent heating

• Heating coil damage from dry firing

• Unsafe system operation

Replacing a worn or malfunctioning pressure switch helps ensure safe burner operation, reliable hot water production, and protection of your pressure washer's heating system.

A critical safety component for maintaining proper burner control and extending the life of your hot water pressure washer.
