Troubleshooting your McCulloch electric pressure washer when it produces weak spray

An insufficient water supply can cause low pressure at the nozzle. Check the water pressure at the source and the flow connected to the inlet of the pressure washer. Check the inlet screen for a clog that could be blocking inlet water flow.

Check whether a low-pressure spray tip is installed on the wand; if so, install a different nozzle. A problem with the wand or pressure hose can also cause low nozzle pressure. Clean or replace the wand if necessary. Replace the pressure hose if it's clogged.

A pump failure can cause low nozzle pressure. Replace the pump check valves or replace the entire pump if it doesn't build up adequate spray pressure. A stuck unloader valve can also cause low pressure at the nozzle. Replace the unloader valve if it sticks open and constantly recirculates water back to the pump inlet.

Top-selling McCulloch electric pressure washer repair parts

  • Unloader valve. The unloader valve opens to relieve water pressure and recirculate water through the pump when the spray wand isn’t in use and the pressure washer is running. Recirculating water helps prevent the pump from overheating when the spray wand isn’t discharging water.
  • Spray tip. The spray tip connects to the end of the spray wand. The spray tip restricts water flow and creates a spray pattern. An assortment of spray tips is usually provided with the pressure washer.
  • Water pump. The water pump is connected to the motor drive shaft. The motor drive shaft spins the pressure washer pump to create the water pressure for the spray nozzle.
  • Pressure hose. The pressure hose connects the pump to the spray wand. The pressure hose carries the pressurized water safely from the pump to the spray wand.
