Can I fix Balboa code dr myself?

Start with these safe checks: Top up the water and check for an airlock after a refill. Turn power off, clean the filter, restore power and press any button. If dr keeps returning, call for service.

When should I call a technician for code dr?

If dr keeps returning, call for service. Water and electricity together can kill. Turn the equipment off at the breaker before you open anything, never touch equipment while standing in water, and stay out of the pool or spa if you feel tingling or suspect an electrical problem. Leave wiring, boards and GFCI faults to a licensed electrician or service tech.
