Why is there no water jet or a weak water jet from my Makita DHW080ZK Pressure Washer?

  A weak or nonexistent water jet from your Makita Pressure Washer can stem from several causes. Check that the faucet is fully open and, if using a suction hose, ensure it's properly primed with water. Inspect the connection between the pressure washer and the water faucet. Also, the hose, filter, or nozzle might be clogged, so clear any blockages. If air is blocking the water flow, turn the switch off and on again while squeezing the trigger. A damaged or worn nozzle can also cause this issue, so consider replacing it.

  An unstable water jet from your Makita Pressure Washer could be due to a few reasons. Start by checking the nozzle for clogs and use a cleaner pin to clear any blockages. Inspect the water hose, starting from the faucet, for leaks or clogs, and make sure the faucet is fully open. If the water is too hot, try supplying cooler water.

  If your Makita Pressure Washer isn't starting, there could be several reasons. First, ensure charged battery cartridges are installed. Check if the switch is turned on. Try pulling the trigger to release any residual pressure in the pump. If the high pressure washer has been left for a long time while maintaining high pressure, switch it off, supply water from a faucet to the inlet, squeeze the trigger while keeping the water supply for a while, and then switch it on again. If none of these steps work, the battery or electric circuit may be damaged.
