Weak solution spray with poor pressure; pattern is uneven or dribbles from jets.

Safety: Disconnect power and relieve pressure before servicing.

• Eliminate air leaks: Check the suction hose from the solution tank to the pump for loose clamps, cracked hose, or damaged fittings. Replace or tighten as needed.
• Clean jets and filters: Remove and clean spray jets and the inline filter as described in the previous scenario.
• Check pump performance: If available, connect a pressure gauge to the solution outlet and compare to Prochem specifications. If pressure is significantly low with clean filters and no air leaks, replace the Prochem solution pump.
• Verify supply voltage: Measure voltage at the pump motor while running. If low, inspect wiring, switches, and connectors for resistance and heat damage.
