The cleaning machine is a kind of equipment that needs to be used in many places. It is mainly used to clean certain equipment, but the cleaning machine is prone to blockage. Because water needs to be used, there may be other impurities in the water without advanced treatment, which will lead to problems in the spray arm. Therefore, check whether there is a problem in the spray arm before checking the cleaning machine.

The spray arm needs to face the target surface, but some cleaning machines will loosen the spray arm when in use, resulting in inclination.

Complete spray arms: some cleaning machines know that the spray arms are missing, but they are still in normal use, and then it is easy to cause the equipment to fail to operate normally, resulting in sudden increase and decrease of water pressure, so that the cleaning effect is not ideal.

Obstacle free rotation of spray arm: test the rotation of spray arm to ensure stability and uniformity.

There are no sundries at the bottom of the drainage screen of the washing machine: the bottom of the washing machine will drain pollutants from the screen of the instrument group. The screen shall be removed and cleaned at least daily, or the cleaning frequency shall be increased according to the frequency of use. Blocking the screen will hinder the flow of water and drainage, thus affecting the cleaning effect of the cleaning machine.
