Mi-T-M 22-0348 Flow Switch

The Mi-T-M 22-0348 Flow Switch detects water flow within the pressure washer system with the electrical controls for proper operation. A faulty switch can interrupt startup, trigger unexpected shutdowns, or affect overall system operation.

Common symptoms include:

• Pressure washer will not start with proper water supply.

• Flow switch fails to detect water movement.

• Intermittent electrical signal from the switch.

• Unexpected shutdown during operation.

• Inconsistent activation of pressure washer system.

Pressure Washer Does Not Start

Quick Check: Confirm water supply is fully turned on and inspect the flow switch connector for secure electrical contact.

Fix Suggestion: Replace the flow switch if it does not respond after verifying proper water flow and electrical continuity.

Prevention Tip: Use clean water and periodically check the switch wiring for damage.

Unexpected System Shutdown

Quick Check: Check for restricted water flow and clogged inlet screen.

Fix Suggestion: Restore proper water flow and replace the flow switch if shutdowns occur during operation.

Prevention Tip: Clean the water inlet screen regularly and avoid operating with restricted water supply.

Flow Switch Fails to Detect Water Movement

Quick Check: Inspect the switch body for debris, mineral buildup, or internal sticking.

Fix Suggestion: Install a new flow switch if cleaning does not restore proper operation.

Prevention Tip: Flush the pressure washer with clean water after use to reduce sediment formation.

Intermittent Electrical Signal

Quick Check: Examine the wiring harness and terminals for corrosion, loose connections, or damaged insulation.

Fix Suggestion: Repair damaged wiring or replace the flow switch if electrical output remains inconsistent.

Prevention Tip: Keep electrical connectors clean and protected from excessive moisture.

Customer Experience: After replacing the Mi-T-M 22-0348 Flow Switch, the pressure washer responded consistently when water flow was established, and unexpected shutdowns that had occurred during regular cleaning were no longer observed.
