Frequently Asked Questions

Common symptoms include no power to the motor, erratic pressure control, tripping the internal fuse, or intermittent operation. Verify the power cord, switch, and capacitor first, then inspect the board for burnt components before replacing.

This kit is specified for X5 (Series E) and X7 (Series D). Other series may use different boards. Check your series on the data label and cross-reference the parts manual if uncertain.

Typically just hand tools (screwdriver, nut driver). Disconnect power, remove the housing, note wire locations or take a photo, swap the board and bracket, then reassemble. Follow the included instructions for torque/sequence.

In most cases, no special calibration is required. After installation, prime with water, then test spray and verify smooth pressure adjustment across the range. If pressure is unstable, recheck wiring, filter, and tip size.

Check the power source, on/off switch, motor brushes (if applicable), transducer/pressure control, and the drive system. Also ensure filters, hose, and spray tip are not blocked, which can mimic electronic faults.
