  If your Daewoo Pressure Washer is leaking pressure, several issues could be the cause. The nozzle might be worn out and needs replacement. Alternatively, the suction and/or delivery valves could be broken or damaged, requiring inspection and potential replacement. Foreign matter in the valves could also be the culprit, so check and clean them. The setting valve area might be worn, necessitating inspection and replacement. Lastly, worn-out seals can cause leakage, so replace them.

  Several factors can prevent your Daewoo Pressure Washer from reaching the correct pressure. The pump might be sucking air, so inspect the suction pipes. Worn-out valves can also cause this issue, requiring inspection and possible replacement. For worn out setting valve area or unsuitable or worn out nozzle, contact an authorised service centre. Finally, worn-out seals can contribute to the problem.

  Irregular pressure fluctuations in your Daewoo Pressure Washer can arise from several causes. The suction and/or delivery valves may be worn out and need replacement. Foreign material in the valves can also cause malfunctions; in this case, check, clean, and replace if necessary. Air suction can also cause this issue, so check the suction pipe. Finally, worn seals can also lead to pressure fluctuations; inspect and replace them as needed.
