Why GMC Pressure Washer doesn't start?
- S
  Sandra MullinsAug 16, 2025
  If your GMC Pressure Washer doesn't start, there are several potential causes. First, the system might be pressurized, in which case you should squeeze the trigger on the lance before starting. Check that the mains plug is fully inserted and the mains socket switch is on. Also, the residual current device (RCD) may have operated and needs resetting. If you are in the UK, the plug fuse may have blown, so replace the fuse; if it blows again immediately, contact your dealer. Finally, the thermal safety switch may have operated, so switch off the pressure washer and allow the motor to cool before restarting.
