WashR FLO | Output pressure varies high and low

If your WashR FLO pressure washer is fluctuating between high and low pressure during operation, it may be struggling with water delivery or an internal blockage. Use the table below to identify the most common causes and how to fix them.

POSSIBLE CAUSES SOLUTION
Not enough inlet water supply Turn the tap on to full force. Inspect the garden hose for any kinks, leaks, or blockages that may be restricting flow.
Pump is sucking in air Check that all hose connections and fittings are airtight. Turn off the unit and squeeze the trigger gun until a steady flow of water emerges to purge the pump of air.
Water inlet filter is clogged Remove the inlet filter and rinse thoroughly with warm water. Use a soft brush or fine needle if needed to dislodge debris.
Calcified gun, hose, or spray wand Mineral build-up may be causing restriction. Run distilled vinegar through the detergent tank to help break down calcium deposits.
Discharge nozzle is obstructed Inspect the nozzle for clogs. Blow out or clear the orifice using a fine needle or nozzle cleaning tool.
