Welcome to the forum! I have a couple of ideas, but would like for you to answer some questions before I get too far off base on the probable cause.
Does it happen before you add new DE to the filter or while you're adding it? What size (HP) is the pump, and what size (sq ft) is the filter (if it's Hayward - you can just give me the model #s) and do you have a multiport? How much DE do you add after each backwash (and how much is recommended for the unit)? Also, how do you measure the DE that you add? One more thing, what is your backwash procedure, I've seen a few different ones recommended. The answers to these should give us a place to start.
Sorry that I didn't see this 'til now, I'm about to log off and may not get back to the forum for a couple of days, however I've run into the same problem countless times and am certain I can help you to correct it. - Waste
