Good To Know

Q: How do I know if this sensor fits my machine? A: Check your machine's serial number and existing part number against the cross-references 157-3182 or 221-8859 to confirm compatibility. Minor differences in connector orientation can occur between production years.

Q: What happens if the sensor fails? A: A faulty pressure sensor can cause erratic pump operation or error codes on the display, leading to reduced performance or unplanned downtime. Replacing it promptly restores accurate pressure readings and system stability.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
