What an unloader does
It diverts pump output back to the tank when the trigger is released, so a positive displacement pump is never deadheading against a closed valve. Without a working unloader the pump has nowhere to send its output, and pressure spikes destroy seals, hoses and eventually the pump itself.
Symptoms of a failing unloader
Pressure that will not adjust, pressure that creeps up while the trigger is released, or a pump that labours and gets hot when the wand is not in use. Any of those means stop and fix it — running on is what turns a valve into a pump.
