My sprayer won't shut off; the battery has to be removed to stop it.

STEP 1: For VARIABLE-PRESSURE sprayers -

Check if the pressure dial is rotating continuously with no stopping point. If so, the dial and circuit board must be replaced.
If the dial is functioning normally, replace the circuit board only.

STEP 2: For DUAL-PRESSURE sprayers -

Replace the circuit board.
