Problem:

I keep getting a dirty filter fault at the particulate filter canisters that are plumbed in line between my pump and my wash manifold. Even when I change the bags I get this fault and then when I change the bags again, the fault activate again.

Solution:

First, congratulations on changing the bags when the machine alerts you to the need to change them. By doing this you are taking positive corrective action and your process will be more successful and your pumps will last longer because of it. Also, you are ahead of 50% of our customers already.

When the filter bags are being changed and the dirty filter faults are still occurring, then you are checking the wrong thing, however. What most customers do not realize is that the warning for the dirty filter is after the filter. When checking the bag, you also need to check the inlet pressure. What is most likely happening is the inlet pump strainer is blocked or there is a pile of sludge, debris or shavings piled on the floor of the tank at the place where the pump suction takes place. Check the inlet, it is as important as the outlet.

If the inlet is blocked by either of the above scenarios, then I will bet that the chip baskets are full and need to be cleaned. If the chip baskets are overflowing rather than allowing water to filter through, then that debris is going to be detrimental to your pump, your nozzles and your process.
