Air Lock DR / DrY error code

Air can get trapped in your heater assembly when filling the hot tub. We always recommend filling via the filter; that way a lot of the air is pushed out as filling progresses.
This video shows two ways to clear the air in your plumbing. This video was easy to shoot as it was done on a Beachcomber that houses the management system under the steps.
Enjoy!

This did the trick. Thank you. After messing about with loosening pipes on the ends of pumps, which didn.t work, you had the correct solution.
